Solar modules Solar modules may only be used if they hold the following valid certification:  IEC 61215/IEC 61646 and protection class II/IEC 61730 Framed solar modules Please note that the guarantee for the solar modules will be rendered void if modifications are made to the module frames (e.g. by drilling additional holes). In order to comply with warranty conditions, the installation instructions of the respective solar module manufacturer must be strictly observed. Lightning and overvoltage protection The lightning and overvoltage protection of the PV system must comply with the current specifications of  DIN/VDE 0185 parts 1 to 4  DIN/VDE 0100 part 712  VdS 2010. Please refer to the specified directives and standards for detailed information. We generally recommend integrating the mounting system and the module frame into the on-site equipotential bonding and using overvoltage protective equipment. Equipotential bonding is always required if the solar modules used do not comply with protection class II and/or transformerless inverters are used. The cross-section of the equipotential bonding conductor must correspond to the cross-section of the DC main cable; however, it must be at least 6mm² (copper). If the building is equipped with a lightning protection system and the PV generator is not located within the protective area of the interception device, the module frame and the mounting system must be integrated into the external lightning protection system and additional overvoltage protective equipment must be installed. The electrically conducting connection must have a minimum core size of 16mm² (copper). Please obtain information on the currently applicable, technological standards!

Laying the cables Starting with the frame installation, several points concerning the direction of power lines and laying of cables should be observed.  To avoid overvoltage couplings from lightning strikes, the resulting conductor loop must be kept to a minimum.  Routed cables must not obstruct any potential snow and ice from sliding down.  Water must not collect around routed cables, ensure continuous water drainage.  Route cables with maximum possible UV and weather protection. Dimensioning Our TopFix 200 mounting system is dimensioned using our very own PV Manager software, used to determine the degree of utilisation and hence the suitability of the components to be mounted on your roof. The software is designed as a planning tool. It does not substitute official, static calculations. If you do not have the PV Manager available for PV plant dimensioning, please contact your responsible sales representative to determine and dimension the mounting system. Important! Any calculations for the roof construction as well as any existing superstructures do not form part of the static calculations as part of the PV substructure dimensioning. A structural engineer must inspect and approve of the increased and rearranged loads caused by the PV plant on site.

03. Mounting diagram There are various possibilities for the arrangement of the mounting system and the modules on the roof. The most common option is to horizontally assemble type e.g. TF50+ carrier rails and arrange solar modules vertically. For this reason, any further mounting procedures describe such an arrangement. Figure 1: View of the IBC TopFix 200 pitched roof mounting system Important! We would like to once again point out that the applicable accident prevention regulations (UVV) must be observed when working on the roof (including VBG 37 construction work, paragraph 12 "Fall protection equipment").

04. Fitting the various mounting systems 4.1 General dimensioning information The PV system on your roof is subject to considerable forces caused by snow and, most of all, wind. Improper fastening of the PV system, particularly the modules, may cause significant damage to objects as well as personal injury. For this purpose, it is crucial you observe the following section. The number of fixing points on the roof is always dependent on the particular design of the roof, building height, roof pitch, the wind and snow load zone and a large number of other factors. The compatibility of the material pairings between the roof and the PV system must be checked before the instalation. Edges and corner areas must be particularly taken into account as per EN 1991-1-4 (Euro code 1) as increased loads may apply due to wind dynamics, depending on the building type. For more detailed information, please see the graphical indications of fixing points in our PV Manager software. Calculate and verify any specific details according to the applicable standards. In this process, we recommend you consult a structural engineer. Before starting installation, the existing wooden substructure must be checked for sufficient stability. The wooden substructure must have a service life of more than 20 years. In case of doubt, consult a roofer or joiner and a structural engineer. As a rule, verify on-site static conditions and whether or not the outer roofing in conjunction with the substructure (steel beams/purlins) is able to bear the additional pressure and dynamic loads of the PV plant. We shall not assume any system liability for the integrity of the roof as this mainly depends on the quality of mounting or subsequent sealing procedures. The rules of the building trade as well as guidelines and instructions of the roofing manufacturer are to be observed. Mounting system parts must not be treated with additional anti-corrosion protection in normal, atmospheric conditions (corrosivity categories C1-C3 according to EN ISO 12944-2 and surrounding temperatures of -30°C to +50°C). Take additional, suitable anti-corrosion protection measures in the event of other assembly locations (e.g. contact with grit, direct vicinity to the coast, acidic or alkaline environments). Modifications that are not permitted and improper use of our components during assembly and construction shall render and liability and guarantee claims void.

4.2 Fitting the roof hooks In order to comply with warranty conditions (rain-proofing etc.) we recommend having the roof hooks fitted by a roofing firm. Please also take into account the manufacturer's regulations and specifications for the corresponding roofing, in particular with regard to the use of manufacturer accessories for roofing as well as the overview in section 11 containing data on the rafter dimensions required as per EN 1995-1-1. Fitting steps:  Remove the roof tile above the rafter.  Place the roof hook in the depression in the pantile and align it centrally.  Screw the roof hook to the rafter using two flat head screws. There is no need to drill holes beforehand.  Align other roof hooks using a piece of string.  Reinsert roofing tile. Important! Do not use fitted roof hooks as a step ladder, as the pantile below could be damaged by the extreme concentrated load! Figure 6: Roof hook on the rafter Figure 7: Fitted roof hook Figure 8: Fitted roof hook Figure 9: Alignment with piece of string Figure 5: Roof hook

If the roof hook cannot be fitted as shown above due to the form of the tile or the position of the depression, it is imperative that a roofer is engaged. Changes to roof covering materials (roof tiles, clay tiles, roof panels, cast stone, etc.) may only be made in accordance with the applicable roofing trade regulations and the manufacturer’s guidelines. Important! The leg of the roof hook lies in the depression in the pantile and must have a clearance of 5mm from the surface of the tile. If necessary an underlay of suitable material should be installed in the space between the rafter and the roof hook’s base plate as per Figure 10. The roofing must not be damaged by loads arising from the fitted roof hooks! If there is a risk of this occurring, additionally install suitable supports to distribute the load. Especially with older tiles, plain tiles and slate roofs and where the installation site is in a high snow load zone, the use of sheet metal supports or tin tiles is recommended. The guidelines of the roofing manufacturer must be observed. The securing screws in the rafters and the rafters themselves are extremely important for the overall system stress. Chipboard screws are not suitable owing to their smaller head diameter. It must screwing the roof hook to the rafter using two approved 8x100 respectively 6x100 flat head screws from our product range, where no pre-drilling is required. Grease screws to facilitate fastening. Roof hooks are suitable for most tile types. In individual cases, it may be necessary to remove small pieces from the roof tiles using an angle grinder and suitable cutting disc to ensure that the tile sits flush. The guidelines of the roofing manufacturer must be observed. Particular attention must be paid to the accident prevention regulations when undertaking this work. If applicable, use wooden base blocks on eccentric roof hook connections to distribute the load according to the following figure. Figure 10: Roof hook load distribution

4.3 Roof hook types Important! The specifications of the general building approval Z-14.4.-661 for steel roof hooks and Z-14.4.-515 for aluminum roof hooks have to be considered. 4.3.1 "Standard S+" roof hook Generally the "Standard" S+" roof hook is used.

4.4 ASD screws- Mounting on rafter-mounted insulation systems ASD screws are designed to install roof hooks on roofs with rafter-mounted insulation roofing. They are designed so the insulation is fitted on the rafters, between the layer of rafters and the battens. This insulation layer must not be subjected to static, individual loads, such as roof hooks. The loads from the roof hooks are diverted through the space between the insulation to the load-bearing rafter design using the ASD screws. Note: If the roof structure is too high over the rafters for the ASD scrwes, the roof hooks can also be fixed in the counter battens. By the customer it must be proofed that the corresponding counter battens are fastend to the substructure so that the additional loads can be absorbed and the function of the insulation is not impaired. Observe the edge distances according Figure 121 Select the required screw length according to Figure 32 or using the IBC SOLAR AG PV Manager dimensioning software. It is not required to drill bores before inserting the screws.

4.6 Installation using M12×300 hanger bolts and M10x200 hanger bolts on the timber substructure. Hanger bolts are used on corrugated eternit and trapezoidal sheet metal roofs as well as bitumen roofs to attach the carrier rails. The load bearing roof construction to which the hanger bolt is secured consists of timber purlins or timber rafters. Compensate for any difference in height of the purlins/rafters using the thread of the hanger bolts. Comply with the valid, generally applicable building surveillance certificate Z-14.4-602 and the regulations contained therein for the use on trapezoidal roofs. The roofing must not be damaged by pressure from the installed hanger bolts. If there is a risk of this, suitable measures must be taken to spread the load. Furthermore, the penetration point of the hanger bolts through the water conducting level should be sealed in accordance with roofing trade regulations. For this reason, we recommend having hanger bolts fitted by a roofing company. Please also observe the guidelines and regulations of the manufacturer of the respective roofing. Proceed as follows during mounting:  Do not drill into the water bearing depressions, but into the protruding parts.  Use the pre-drilling diamters and screwing depths illustrated in Figure 48. Hanger bolt pre-drilling diameter [mm] Screwing depth lef [mm] Hanger bolt M12x300 A2 8,4 48…100 Hanger bolt M10x200 A2 7,0 40…67 Figure 48: pre-drilling diameters for plate and substructure; screwing depths for substructure  Determine the rafter position (potentially mark using a piece of string). Drill the bores into the outer roofing (e.g. sheet metal, corrugated eternit) and rafters. Subsequently drill 15mm bores into the outer roofing.  Tighten the lower nut on the machine thread to press the rubber seal against the outer roofing, thus sealing the hole.  Carefully press down the seal. Risk of cracks and deformation!  For stress reasons, the distance to the roofing must be kept as small as possible. Figure 47: Hanger bolt

l =100 mm  Cut hanger bolts using an angle grinder if they protrude too far (comply with accident prevention regulations).  For stress reasons, the universal connector must always be mounted in the direction of the roof ridge. Important! The stress values for the M12x300 hanger bolt relate to a fixing distance l = 100mm for a use of corrugated eternit panels. Exceeding the fixing distance has a detrimental effect on static values. The calculation in the PV Manager software is based on a fixing distance of l = 100 mm. Important! Always install universal connectors in each row of modules, as shown on the figure. Figure 49: Correctly fitted hanger bolt with universal connector Figure 50: Fixing distance Figure 51: Mounted hanger bolt with "universal connector"

4.7 Assembly with solar fasteners on a steel substructure Solar fasteners are intended for attachment to metal purlin or rafter structures with roofing made of trapezoidal profiles and sandwich profiles. In this process, the outer shell is made either of steel or aluminium. Just as with hanger bolts, solar fasteners are inserted through the roofing and fastened to the substructure. Comply with the valid, generally applicable building surveillance certificate Z-14.4-638 and the regulations contained therein for the use on trapezoidal sheet metal and sandwich roofs. Proceed as follows during mounting:  Do not drill into the water bearing depressions, but into the protruding parts.  Determine the rafter/purlin position (potentially mark using a piece of string).  Drill 11 mm bores into the outer roofing (sheet metal).  Depending on the thickness of the steel, drill into the metal substructure accordingly to fasten the solar fasteners. For this purpose, take into account the data illustrated in Figure 53 below. Thickness of the steel substructure [mm] 1.5 < 5.0 5.0 < 8.0 8.0 < 10 > 10 Pre-drilling diameter [mm] 6.8 7 7.2 7.4 Figure 53: Steel substructure pre-drilling diameter  Screw the solar fastener into the steel substructure to safeguard it demonstrates secure static properties.  Tighten the lower nut on the machine thread to press the rubber seal against the outer roofing, thus sealing the hole.  Carefully press down the seal. Risk of cracks and deformation!  For stress reasons, the universal connector must always be mounted in the direction of the roof ridge.  Adapt the required length of the solar fastener to the height of the roof structure. Use IBC SOLAR AG's very own "PV Manager" planning software to ensure you select the right solar fastener. Figure 52: Solar fastener

Please note: Comply with the following requirements regarding the roof profile type:  The nominal sheet metal profile panel thickness around the fasteners is ≥ 0.4 mm for steel and ≥ 0.5 mm for aluminium.  The nominal width of the outer layer of the sandwich element around the fasteners is ≥ 0.4 mm.  The nominal width of the steel substructure (rafters/purlins) around the fasteners is ≥ 1.5 mm.  The available rib height h for sandwich roofs is 35 mm ≤ h ≤ 45 mm  The available upper belt width b for sandwich roofs is 20 mm ≤ b ≤ 40 mm  When putting a load on solar fasteners in a transverse direction to the profile panels, the profile panels must be fastened to the corrugated elements on the substructure that are in the vicinity and at the same height.  For additional framework conditions, see the valid version of the Z-14.4-638 certificate.

4.8 Mounting plate duo The mounting plate duo is used for fixing with two hanger bolts or two solar fasteners. The two screws are connected through the mounting plate duo. The rooftop connector profile is then fixed on the mounting plate duo. There are two different variants for connecting the profiles. For fixing a TF60 profile, only a RH-profile connecting element is required in accordance with Figure 55. For fixing the profiles TF50+ and TF50m, on the other hand, a universal connector and additional screws for fixing the universal connector are required in accordance with Figure 54. The mounting plate duo can be used for trapezoidal sheet or corrugated eternit roof coverings. The maximum high-beading space must be 330 mm. Component length mounting plate duo: 370 mm Figure 54: Mounting plate Duo with universal connector Figure 55: Mounting plate duo with connecting element RH-profile

4.9 Mounting with trapezoidal sheet metal clamps 4.9.1 Introduction IBC SOLAR AG trapezoidal sheet metal mounting in combination with the IBC TopFix 200 mounting system is a fast, universal and structurally tested solution for attaching solar modules onto trapezoidal sheet metal roofs. It will be secured either by rivets or self drilling screws. Please note:  The minimum trapezoidal sheet thickness of steel or aluminium must be 0.5 mm.  The enclosed special 4.8×15 blind rivets with flat, round head are certified for a sheet metal or aluminium thickness of between 0.5 mm and 1.5 mm.  Observe the ETA-13/0255 for the blind riverts.  The enclosed self drilling screws 5,5x25 are certified for a sheet metal or aluminium thickness of between 0.5 mm and 1.5 mm.  Observe the ETA-10/0200 for the self drilling screws.  Do not fall below the raised bead support width of 15 mm.  The maximum width b of the raised bead must not exceed 40 mm.  Because additional loads are created by the PV system in connection with the IBC mounting system and fixing points (fixed-points) and wind suction, the installer (contractor) has to check the statics of the load capacity of the roofing and the substructure, which normally requires the services of a structural engineer.  Special-purpose assembly on narrow raised beads, sandwich elements and elevations must be verified on-site as part of individual statics inspections and a certificate for sandwich profiles may have to be obtained from building surveillance authorities. Important: Do not mount trapezoidal sheet clamps on the trapezoidal sheet metal panel blocks (two layers of sheet metal)! 4.9.2 Required tools/auxiliary agents*  Riveter (by connection with rivets)  Drill, Ø 5.0 mm (by connection with rivets)  Socket wrench 6-kant SW8 (when mounted with self drilling screws)  Cleaning agent  Lint-free paper towels  Cleaning fleece for badly contaminated roofs

* The listed tools and auxiliary agents are required exclusively for installation and processing of the trapezoidal sheet metal panels. Information about tools for module and carrier rail mounting is provided in section 1 in these installation instructions. 4.9.3 Dimensioning The mounting system is dimensioned in our very own PV Manager software, taking into account local conditions. Important: Do no exceed a maximum carrier profile length of 3 beams (approximately 15.60 m) for continuous carrier rails due to thermal expansion. 4.9.4 Mounting trapezoidal sheet metal panels Step 1: Dimensioning using "PV Manager" Step 2: Mark the fixing points of the clamp Step 3: Clean the roofing Exclusively clean the roofing in areas where you intend to affix trapezoidal clamps at a later point. The surfaces must be dry and free from grease, oil or silicone as well as dirt particles to safeguard optimum integrity. In the event of heavy-duty contamination, we recommend to carefully roughen up the surface with suitable materials (e.g. fleece cleaning cloth) to subsequently clean it. We recommend using isopropyl alcohol or acetone in combination with lint-free paper towels for cleaning. Important: Please observe the safety regulations when handling solvents and chemicals. Figure 56: Marking fixing points

Step 4: Affix the TRAPEZOIDAL CLAMP Note: The heavy-duty adhesive tape can be used from an object and working temperature of 0° C; final adhesion occurs after approx. 72 h at an ambient temperature of 20° C. The higher the temperatures, the faster this process is complete. We do not recommend to bond surfaces below these temperatures as the adhesive agent may become too hard and prevent adequate adhesion. After adhesion has taken place, low temperatures do not normally create any problems. Prevent the formation of condensation to safeguard appropriate adhesive properties, for instance in the event that the materials to be bonded together are at very different temperatures.  TRAPEZOIDAL CLAMPS are aligned with the adjustable element towards the ridge and affixed to the surface so that the type TF27 carrier rail can be mounted without tension and it is in contact with the trapezoidal sheet clamp. Please fully remove the protective foil! Figure 57: Removing the protective foil Figure 58: Affixing the trapezoidal clamp Step 5: Distribute the clamps according to the instructions Figure 59: Distribute the clamps according to the instructions

Step 6: Insert and align the TF27-T carrier rail Figure 60: Insert the carrier rail Figure 61: Align the carrier rail Figure 62: Close the clamp Step 7A: Affix the TRAPEZOIDAL CLAMP to the outer roofing with blind rivets Important: A drill with a diameter of 5.0 mm is mandatory to maintain static properties!  When using the rivets drill two bores with a diameter of 5.0 mm per TRAPEZOIDAL CLAMP . In this process, make sure you drill carefully to maintain static properties.  Now insert the 4.8x15mm blind rivets into the bores and rivet.  The enclosed 4.8x15 mm blind rivets are approved for a sheet metal or aluminium thickness of 0.5 mm to 1.5 mm. Figure 65: Inserting blind rivets Figure 66: Riveting using a standard rivet head Figure 63: Mount carrier rail Figure 64: Drilling clamps

Step 7B: Affix the TRAPEZOIDAL CLAMP to the outer roofing with self drilling screws  When using the self drilling screws, two screws are placed per TRAPEZOIDAL CLAMP. In this process, make sure you screw carefully to maintain static properties.  The enclosed self drilling screws 5,5x25 are approved for a sheet metal or aluminium thickness of 0.5 mm to 1.5 mm. Important: A drill with a diameter of 5.0 mm is mandatory to maintain static properties Step 8A: Insert and affix the transverse securing clamp with blind rivets  The transverse securing clamps are affixed next to the trapezoidal clamp on the left and right with a clearance of approximately 20 mm.  There must be a minimum of two transverse securing clamp per string (15.60 m). Important: Mount additional transverse securing clamps on roofs that are particularly exposed to wind. Figure 69: Insert transverse securing clamps Figure 70: Drilling transverse securing clamps Figure 67 Apply the screw Figure 68 Trapezoidal clamp screwed

 Now insert the 4.8x15mm blind rivets into the bores and rivet. Figure 71: Rivet transverse securing clamps Step 8B: Insert and affix the transverse securing clamp with self drilling screws  The transverse securing clamps are affixed next to the trapezoidal clamp on the left and right with a clearance of approximately 20 mm.  There must be a minimum of two transverse securing clamp per string (15.60 m). Important: Mount additional transverse securing clamps on roofs that are particularly exposed to wind. Figure 72 Screwed transverse securing clamps

Step 9: If required: Insert butt connector  Butt connectors are inserted via the TF27 carrier rail and fixed. Figure 73: Insert butt connectors Figure 74: Joining together the carrier rails  The butt connector is either attached using two 4.8x15 mm blind rivets (pre-drilling) or two 5.5x25 mm self drilling screws.

4.9.5 Eco trapezoidal system The Eco trapezoidal system is a pre-assembled, short-rail system to which trapezoidal profiles are riveted or scrwed together. Important: Thermal expansion dictates a thermal separation after 15 modules in one row. Step 1: Dimensioning using "PV Manager" Step 2: Mark the fixing points of the clamp Step 3: Clean the roofing Exclusively clean the roofing in areas where you intend to affix trapezoidal clamps at a later point. The surfaces must be dry and free from grease, oil or silicone as well as dirt particles to safeguard optimum integrity. In the event of heavy-duty contamination, we recommend to carefully roughen up the surface with suitable materials (e.g. fleece cleaning cloth) to subsequently clean it. We recommend using isopropyl alcohol or acetone in combination with lint-free paper towels for cleaning. Important: Please observe the safety regulations when handling solvents and chemicals. Figure 75: Marking fixing points

Step 4: Affixing the "Eco trapezoidal system" Step 5: Distributing the "Eco trapezoidal system" as specified Step 6A: Affix "Eco trapezoidal system" to the outer roofing with blind rivets Important: A drill with a diameter of 5.0 mm is mandatory to maintain static properties!  When using the riverts drill two bores with a diameter of 5.0 mm per "clamp base". In this process, make sure you drill carefully to maintain static properties.  Now insert the 4.8x15mm sheet blind rivets into the bores and rivet.  The enclosed 4.8x15 mm sheet blind rivets are approved for a sheet metal or aluminium thickness of between 0.5 mm and 1.5 mm. Figure 76: Removing the protective foil Figure 77: Affixing the "Eco trapezoidal system" Figure 78: "Eco trapezoidal system" distributed as specified Figure 79: Drilling clamps

Figure 80: Inserting blind rivets Figure 81: Riveting using a standard rivet head Step 6A: Affix "Eco trapezoidal system" to the outer roofing with blind rivets  When using the self drilling screws, two screws are placed per “clamp base”. In this process, make sure you screw carefully to maintain static properties.  The enclosed self drilling screws 5,5x25 are approved for a sheet metal or aluminium thickness of 0.5 mm to 1.5 mm. Figure 82 Apply the screw Figure 83 Eco trapezoidal screwed

Step 7: Alignment of PV modules Figure 84: Aligning PV modules

4.10 Installation of sheet seam clamps Special fastening elements are used to fasten PV modules on standing seam roofs, which are then attached to the carrier rails. The roofing must not be damaged by the load on the installed clamps. For this reason, we recommend having sheet seam clamps fitted by a roofing company.The tightening torque of the sheet seam clamp must be limited in such a way that the sheet metal is not deformed and the thermal expansion of the sheets is not hindered. The clamps are mounted vertically according to the number of carrier rails. As a rule, fit one standing seam to each clamp. On each side the carrier rail must protrude by a maximum of 0.3 m. Observe the thermal separations of the profiles after 3.1m or the spezifications of the respective sheet seam manufactures. Important! Clarify on site whether the roof and the substructure are able to withstand the additional forces caused by installing the PV system. If you intend to assemble PV plants on standing seam roofs, the roof must not only carry the additional loads, it must also withstand the additional wind dynamics. A structural engineer must check the number of fixing points (sheet seam clamps) according to the on-site conditions. Keep the alternator size to a minimum to minimise occurring voltage values. A connection on titan's zinc roofs or copper roofs is not recommended. In advance the clamp should be checked for correct fit and material compatibility. 4.11 Installation of Kalzip® clamps Use "Kalzip® clamps" to fasten the system on so-called Kalzip® roofs. The clamps are distributed vertically according to the number of cross girders. As a rule, fit one standing seam to each clamp. On each side the carrier rail must protrude by a maximum of 0.3 m. Important! Clarify on site whether the roof and the substructure are able to withstand the additional forces caused by installing the PV system. If you intend to assemble PV plants on standing seam roofs, the roof must not only carry the additional loads, it must also withstand the additional wind dynamics. A structural engineer must check the number of fixing points (sheet seam clamps) according to the on-site conditions. Keep the alternator size to a minimum to minimise occurring voltage values. A connection on titan's zinc roofs or copper roofs is not recommended. In advance the clamp should be checked for correct fit and material compatibility. Please also take into account the manufacturer's specifications for the corresponding roofing, as well as the specifications of the corresponding general building approval Z-14.4-560! Figure 86: Kalzip® clamp with universal connector Figure 85: Sheet seam clamp with universal connector

05. Fitting carrier rails  Insert the pre-assembled securing screw (M10 connection piece for roof hook profile) through the roof hook slot. Rotate by 90° and insert into the mounting groove of the e.g. TF50+ carrier rail. Connect TF50+ carrier rail to the roof hooks at the required height and tighten the screw. Important: Please ensure all teeth of the type e.g. TF50+ carrier rail have engaged in the recess!  Start with the top or the bottom carrier rail. Align the screws with the fixing points (e.g. roof hooks) and secure them. See Figure 87.  If required, extend the carrier profiles using butt connectors. Butt connectors enable ideal alignment of the carrier rails.  Do no exceed a maximum carrier rail length of 3 rods (approximately 15,60 m) for continuous carrier rails due to thermal expansion.  Prevent any water from collecting in the carrier rails to prevent frost damage. Figure 89: Fitting carrier rails Figure 87: Carrier rail, fitted Figure 88: Mounting carrier rails

Important! Do not use fitted carrier rails as step ladders! Figure 90: Butt connectors for type TF50 carrier rails Important! Ensure that all T-head screws and hammer nuts have engaged with the rail so they are completely inserted. Note:  Interlocking has been provided on roof hooks and type e.g. TF50+ carrier rails to compensate for differences in height on uneven roofs.  Any carrier rails installed above each other must be in parallel. For this purpose, align the bottom carrier rail horizontally first.  The ends of the rows must be aligned at an exact right angle (90°) to the bottom rail, as otherwise it will not be possible to align the joints between the modules.  Once the carrier rails have been aligned, re-tighten IBC SOLAR AG screws to the corresponding tightening torque and re-check.

Figure 91 Assembled clamps (sectional view) 06. Fitting PV modules The middle and outer clamp are delivered pre- assembled. The middle clamp G3 covers a clamping area of 30-50 mm. However the outer clamp G3 must be ordered for each module height. G3 Middle and outside clamp The middle clamp G4 covers a clamping area of 33-46 mm. The EC adapter is installed with the middle clamp G4 or G3 and replaces the traditional outer clamp. G4 middle clamp and EC adapter Important information: Depending on the height of the module frame, a different version of the outer clamp G3 will be required. The EC adapter for G4 middle clamp covers only the frame sizes 33, 35, 38, 40, 45 and 46mm. The tightening torque of the clamps must 15 Nm! Do not use a ratchet or a wrench with high leverage as the maximum tightening torque could easily be exceeded. Please only use a Torx screwdriver with T-handle or cordless screwdrivers with the appropriate torque settings. A Solar module B G3 Middle clamp C TF50+ carrier rail D G3 Outside clamp

 The middle and outside clamps can be inserted into the carrier rail directly from the top, into the position where they are required.  The middle clamp G4 is swiveled into the carrier rail, where it is needed Important! The slot nut of the G4 clamp must be aligned as shown in the Figure 93 and must not be installed twisted. Figure 93 Inserting middle clamps G4 Figure 92 Inserting middle clamps G3

 The adaptor EC is clamped by the given frame height with the middle clamp G4 and substitutes thus the outer clamp.  Subsequently place the first module onto both carrier rails, loosely tighten it to the outside clamps respectively the middle clamp including EC adapter and align with the row of roof tiles. You may also use a piece of string to facilitate alignment. Then tighten the clamps to the tightening torque specified in Figure 120 in the Appendix. For this purpose, we recommend using a torque wrench with TX40 Torx bit size.  Also tighten all remaining modules in this way. We recommend you start with the bottom row of modules. Assemble all other rows above once it has been exactly aligned.  Please observe the specifications of the currently valid Z-14.4-660 building surveillance certificate. Figure 94 EC adapter with middle clamp G4 Figure 95 EC adapter frame hights

07. Fitting cable clips The cable clips are used to fix the module connector cables and prevent sagging of the cable. The clips can be clamped to the carrier rails of the mounting system TopFix 200 or to the photovoltaic module frames without any tools. Figure 96 shows the attachment of the cable clips 0° at the PV-module frame. In Figure 97 the cable clip is shown schematically 90° on a support profile. Figure 96: cable clip 0° on module frame Figure 97: cable clip 90° on support profile

08. Fitting the two-layer carrier system 8.1 General information In contrast to single-layer carrier rails, this method additionally employs carrier rails as so-called roof hook connecting rails before the actual carrier rail is fitted. 8.2 Type e.g. TF50+ roof hook connecting rails Description L = (MB + 24 mm) × n + 32 mm Carrier rail length = (MB + 24 mm) × number of modules per row + 32 mm L2 = (MH +20 mm) × n2 – 20 mm Roof hook connecting rail length = (MH + 20 mm) × number of module rows – 20 mm MB Module width MH Module height A TF50+/TF50m/TF60 roof hook connecting rails B Type TF50+/TF50m/TF60 carrier rail Figure 98: Roof hook connecting rails and carrier rails as a unit

Dimensioning: Two-layer systems are dimensioned in the same way as single-layer systems. However, the following special features must be taken into account:  Plan for one roof hook per area where carrier rail and roof hook connecting rail meet.  Please also take into account the static values of roof hook connecting rails in addition to the roof hooks and carrier profiles. Use the PV Manager software to determine the static dimensions.  We do not recommend you exceed a maximum carrier rail length of 3 rods (approximately 15,60 m) due to thermal expansion. C Roof hook D Two-layer connector E Max. 400mm F As per PV Manager Z Max. ¼ of the module height (please observe module manufacturer specifications) Figure 99 Cross section of a two-layer system structure

09. Delta support Figure 100: Delta support 9.1 General information Delta supports enable to use the IBC TopFix 200 mounting system as an elevated mounting system and achieve optimum module inclination. Delta supports are available with single as well as continuous base rails. Inclination angles between 10° and 45° can be adjusted in 5° steps. Figure 101: Delta support with single base rail Figure 102: Delta support with continuous base rail

9.2 Assembly Assembling single Delta supports Figure 103: Assembling Delta supports using single base rails Delta supports with single base rails are supplied as complete, folded and pre-assembled units, including three M8×50 hex screws with self-locking nut and tube sleeves. Secure the unfolded support using screw connections. After having finished assembling, all screw connections must be tightened to 15 Nm. Assembling continuous Delta support Figure 104: Delta support with continuous base rail Figure 105: Centering groove for drilling Delta supports with continuous base rail are delivered as pre-assembled units without base rail. The continuous base rail is delivered as 4.9m. The 12.5mm holes in the base rail must be drilled on site in the centering groove. The hole spacing within the Delta support is 1290mm. The row spacing is individually manufactured according to the project. Connect pre-assembled Delta supports to the base rail using two screw connections. After having finished assembling, all screw connections must be tightened to 15 Nm.

9.3 Connection to the roof We offer the following connection types to connect Delta supports, depending on the available roof seal and roof substructure:  Fixation by hanger bolt  Fixation by universal connector  Fixation by additional weight (e.g. positioning walkways, etc.)  Fixation by trapezoidal clamps (two-layer connection with TF27)  Fixation by roof hooks (single or two-layer connection) Figure 106: Fixation by hanger bolt Figure 107: Fixation by universal connector

9.4 Mounting modules Modules can be mounted either horizontally or vertically using Delta supports. Modules up to a module size of 1.7 m can are suitable for vertical mounting.  Vertical module – clamps on the long sides In this case, Delta supports are connected using two carrier rails (TF50+/TF50m/TF60). Modules are then mounted on said carrier rails.  Horizontal module – clamps on the short sides In this case, Delta supports are connected using two carrier rails (TF50/TF50m/TF60). Modules are then mounted on said carrier rails. Please ensure that the modules have been approved for clamping on the short sides.  Horizontal module – clamps on the long sides In this assembly process, modules are mounted directly on the Delta support. In this case, no further carrier rails are used. However, two Delta supports are required per module. Figure 109: Vertically mounted modules with module carrier rail Figure 110: Horizontally mounted modules with module carrier profiles Figure 111: Horizontally mounted modules without module carrier rail

10. IBC FrameFix module frame reinforcements General information We recommend retrofitting IBC FrameFix frame reinforcements in regions with a high degree of snow loads. A high degree of snow loads on vertically mounted modules may deform the frame and hence render the module unusable. IBC FrameFix counteracts this and reinforces the frame from the rear. The structure is not visible and it does affect the mounting system.  Frame reinforcement for large-scale, vertically mounted PV modules (48, 60 and 72 cells)  For module frame dimensions (with adatper) (length/width/height): 1660-1680 mm/990 mm/40–50 mm (1640-1659 mm/ ca. 990 mm/ 40-50 mm) 1580-1620 mm/ 800 mm/40-50 mm 1310-1340 mm/990 mm/40-50 mm  Cable capacity up to 8 kN (800 kg)  Mounting in a few simple steps  Module frame not affected by additional drilling  In the event of subsequent repairs to the PV generator it is merely required to remove the module, not the entire mounting system Assembly  If necessary, insert the adapter on the cable frorm the clamping shoe.  Insert FrameFix corner bracket into the module frame from the rear  Align the cable structure  Pull the tensioning piece over the frame  Pre-tighten FrameFix to 5 Nm Important! Prevent advance frame deformation caused by FrameFix. Figure 112: Assembled FrameFix

12. Appendix 12.1 Notes on IBC TopFix 200 Tightening torques for screw connections The tightening torques for the screw connections used in the IBC TopFix200 mounting system must be dimensioned in accordance with DIN ISO 3506, to document and archive for 10 years. Due to the difficulty in determining the outdoor friction coefficients, dimensioning in accordance with DIN ISO 3506 can prove difficult. We therefore recommend the following tightening torques: Screw connection Tightening torque M8 15 Nm M8 connection piece for roof hook-profile 30 Nm M10 30 Nm Figure 120: Pre-tension for screws We do not recommend using a wrench as this may quickly cause you to exceed the tightening torque. It is sufficient to use a torque wrench or a hex spanner with T-grip. Important! When using laminate clamps, please clarify the tightening torque for the corresponding assembly situation with the laminate manufacturer.

Required rafter and purlin dimensions Comply with the following minimum dimensions for rafters and purlins as per EN 1995-1-1. The minimum rafter/purlin height must be 100 mm. The minimum distance between fastened flat head screws and the edges of rafters and purlins must be three times the flat head screw diameter. Position hanger bolts in the centre of rafters and outside the centre on purlins. Figure 122: Defining the distance to the edge of rafters Figure 123: Defining the distance to the edge of purlins Figure 121: Minimum distance and required timber component dimensions

12.2 Weights/installation times for pitched roof installations Weight per m² of module surface Weight per kWp Thin-film solar modules 10 … 17 kg/m² 130 … 300 kg/kWp Crystalline solar modules 11 … 21 kg/m² 70 … 175 kg/kWp Single-layer mounting system *2.4 … 5 kg/m² *18 … 35 kg/kWp Two-layer mounting system *5 … 7 kg/m² *35 … 50 kg/kWp * Values are based on crystalline solar modules, the weight of the mounting system increases with thin-film solar modules. Installation times: It will take two installers approximately 1-2 hours to install a PV system with an output of 1 kWp (under normal conditions). All specified values are theoretical values. In practical application, installation times and weights may vary, depending on the system version. Weights and installation times for DC cabling, ground and lightning protection have not been taken into account.

12.3 Notes on maintenance The IBC TopFix 200 mounting system is largely maintenance-free thanks to the materials used. In addition to the electrical inspections prescribed for the entire PV system, we recommend inspections of the PV generator every two years, considering the following points. Check:  Solar modules for damage and dirt  All mechanical connections are firmly secured (re-tightening screw connections)  Mounting system and module frame for mechanical damage caused by snow and ice loads  Integrity of the outer roofing  All electrical cables for damage (e.g. by animals)  All electrical plug and screw connections are secure and protected against accidental contact If it becomes necessary to clean the modules, this must be done without chemical cleaning products and using clear water only. The modules can easily be replaced by removing the module cabling and undoing the corresponding module clamps. In this process, please observe the relevant safety requirements.
