The unit is intended for point-of-entry or sub-board protection and is connected in parallel with the power system via HRC fuses. This unit is available in various models for different voltages and applications. Check that the model you have purchased is rated correctly for your power system. . This model (SPD3Gi/A) is designed for TN-S and TT power systems in the range of 220-300V(380- 520V). If your power system is TN-C, TNC-S or IT, or of a different voltage, this model is NOT suitable. Please contact your supplier for a suitable model to suit your application. OPERATION Two lamps on the front panel indicate the operation status of the unit. The ‘OK’ lamp indicates that power is applied to the unit and the ‘FAULT’ lamp indicates reduced protection. If the ‘FAULT’ lamp is lit it is likely that the unit is damaged and must be replaced. If the breaker/fuse is intact and power is definitely being supplied through the unit (check with meter) but the ‘OK’ lamp doesn’t light then the unit is faulty and must be replaced. WARRANTY Eaton Power Quality warrants this unit against faulty parts and workmanship for a period of 12 months from the date of purchase. If this product fails to operate correctly, please contact your Eaton representative. This warranty doesn’t cover neglect or intentional misuse. As this product is intended for use in electrically harsh environments no claim is made of suitability for purpose. This unit is designed to reduce the likelihood of damage, not prevent it. Please also note that an excessive surge, such as from a direct lightning strike to the site or a power system fault, may cause damage to the unit and render it inoperable. A unit that has been damaged in this way is not warrantable. For installation details, see over page. SPECIFICATIONS Manufacturers name and model Eaton Powerware SPD3Gi/A Method of mounting Fixed.

Technical Specification – SPD3Gi/A Tvss Doc# 510075 Page 2 of 2 Web: http://www.powerware.com.au Phone: 1300 UPS UPS WARNING – OBSERVE THE SUPPLY VOLTAGE LIMITATIONS OF THIS UNIT. FAILURE TO OBSERVE THIS WARNING WILL RESULT IN DAMAGE TO THE UNIT. DAMAGE FROM EXCESSIVE SUPPLY VOLTAGE IS NOT WARRANTABLE. INSTALLATION Refer to the procedure and diagram shown to connect the SPD3Gi/A. PROCEDURE: 1. CHECK • Always work safely – disconnect power before making connections. • All wiring must be carried out by suitably qualified personnel according to the applicable standards. • Check for correct operating voltage and power system. This model (SPD3Gi/A) is designed for TN-S and TT power systems in the range of 220-300V(380-520V). If your power system is TN-C, TNC-S or IT, or of a different voltage, this model is not suitable. Please contact your supplier for a suitable model to suit your application. • Always use the correct size HRC fuses. • For services >125A, use 125A fuses. For services <125A, use one step below service fuses (i.e. 80A service = 63A fuses). DO NOT USE A 3-PHASE MCB. • Always use Gg or Gl-rated fuses. Do not use delay types or ‘semiconductor’ fuses. • Consider fitting a fuse-switch or a separate isolation switch to facilitate safe maintenance in the future. 2. INSTALL • Locate a fuse position as close as possible to the Main Switch. • Install fuseholders or fuse-switch. • Locate a suitable position for the SPD3, ensuring adequate space for cables. Do not install above heat- generating objects or in any position that is exposed to weather. • Install unit to DIN-rail in switchboard or cabinet. 3. CONNECT • Connect wiring - refer to connection diagram. If using stranded cable, always use wire ferrules for lowest resistance and to prevent damage to the wire. • Use a suitably-rated cable for power connections. Cable should be rated for operation at the system voltage and should be 4mm 2 to 16mm 2. • Use short cables for phase, neutral and earth connections or protection will be reduced. • Use a suitably-rated cable for alarm connections. Cable should be rated for operation at the system voltage and should be 0.5mm 2 to 1.5mm 2. 4. NOTES: • 125A fuses are rated such for maximum surge rating. On services below 150A, use the correspondingly lower sized fuse (i.e. 80A service = 63A fuse). • Wiring from fuse to SPD is carrying surge currents only, not load current. This means that smaller cables may be used than is normal for the current rating. • If using under-sized cables, some energy authorities require double insulation (i.e. sleeving) of the cables. • Maximum alarm relay resistive load is 5A. • It is recommended not to connect the alarm contacts to AC mains circuits if possible, to prevent flashover from surges on the AC line. Connect to a PLC or BMS if available. • Do not Megger test cabling with unit connected – unit may be damaged. EARTHING For proper operation, all surge diverters rely upon a good earth connection. In some installations the existing earth system may require upgrading. Important things to look for are: • The main earth wire (from earth link on switchboard to ground rod or system) MUST be at least 6mm diameter (preferably larger) and should be as short as possible. • Earth connections from the unit to earth link MUST be as short as possible. Failure to consider the above points can result in improper operation of the unit and possible damage to the installation. If you experience any problems with the installation or commissioning, contact your Eaton representative for guidance.
