Danger: Indicates a risk of electric shock, which, if not avoided, could result in damage to the equipment and possible injury or death. This variable speed drive product (Optidrive) is intended for professional incorporation into complete equipment or systems as part of a fixed installation. If installed incorrectly it may present a safety hazard. The Optidrive uses high voltages and currents, carries a high level of stored electrical energy, and is used to control mechanical plant that may cause injury. Close attention is required to system design and electrical installation to avoid hazards in either normal operation or in the event of equipment malfunction. Only qualified electricians are allowed to install and maintain this product. System design, installation, commissioning and maintenance must be carried out only by personnel who have the necessary training and experience. They must carefully read this safety information and the instructions in this Guide and follow all information regarding transport, storage, installation and use of the Optidrive, including the specified environmental limitations. Do not perform any flash test or voltage withstand test on the Optidrive. Any electrical measurements required should be carried out with the Optidrive disconnected. Electric shock hazard! Disconnect and ISOLATE the Optidrive before attempting any work on it. High voltages are present at the terminals and within the drive for up to 10 minutes after disconnection of the electrical supply. Always ensure by using a suitable multimeter that no voltage is present on any drive power terminals prior to commencing any work. Where supply to the drive is through a plug and socket connector, do not disconnect until 10 minutes have elapsed after turning off the supply. Ensure correct earthing connections. The earth cable must be sufficient to carry the maximum supply fault current which normally will be limited by the fuses or MCB. Suitably rated fuses or MCB should be fitted in the mains supply to the drive, according to any local legislation or codes. Ensure correct earthing connections and cable selection as per defined by local legislation or codes. The drive may have a leakage current of greater than 3.5mA; furthermore the earth cable must be sufficient to carry the maximum supply fault current which normally will be limited by the fuses or MCB. Suitably rated fuses or MCB should be fitted in the mains supply to the drive, according to any local legislation or codes. Do not carry out any work on the drive control cables whilst power is applied to the drive or to the external control circuits. Danger: Indicates a potentially hazardous situation other than electrical, which if not avoided, could result in damage to property. Within the European Union, all machinery in which this product is used must comply with Directive 2006/42/EC, Safety of Machinery. In particular, the machine manufacturer is responsible for providing a main switch and ensuring the electrical equipment complies with EN60204-1. The level of integrity offered by the Optidrive control input functions – for example stop/start, forward/reverse and maximum speed is not sufficient for use in safety-critical applications without independent channels of protection. All applications where malfunction could cause injury or loss of life must be subject to a risk assessment and further protection provided where needed. The driven motor can start at power up if the enable input signal is present. The STOP function does not remove potentially lethal high voltages. ISOLATE the drive and wait 10 minutes before starting any work on it. Never carry out any work on the Drive, Motor or Motor cable whilst the input power is still applied. The Optidrive can be programmed to operate the driven motor at speeds above or below the speed achieved when connecting the motor directly to the mains supply.

www.invertekdrives.com 3 Mechanical Installation 3.4. Guidelines for Enclosure Mounting �� IP20 drives are suitable for use in pollution degree 1 environments, according to IEC-664-1. For pollution degree 2 or higher environments, drives should be mounted in a suitable control cabinet with sufficient ingress protection to maintain a pollution degree 1 environment around the drive. �� Enclosures should be made from a thermally conductive material. �� Ensure the minimum air gap clearances around the drive as shown below are observed when mounting the drive. �� Where ventilated enclosures are used, there should be venting above the drive and below the drive to ensure good air circulation. Air should be drawn in below the drive and expelled above the drive. �� In any environments where the conditions require it, the enclosure must be designed to protect the Optidrive against ingress of airborne dust, corrosive gases or liquids, conductive contaminants (such as condensation, carbon dust, and metallic particles) and sprays or splashing water from all directions. �� High moisture, salt or chemical content environments should use a suitably sealed (non-vented) enclosure. �� The enclosure design and layout should ensure that the adequate ventilation paths and clearances are left to allow air to circulate through the drive heatsink. Invertek Drives recommend the following minimum sizes for drives mounted in non-ventilated metallic enclosures: Drive Size X Above & Below Y Either Side Z Between Recommended airflow mm in mm in mm in CFM (ft3/min) 1 50 1.97 50 1.97 33 1.30 11 2 75 2.95 50 1.97 46 1.81 22 3 100 3.94 50 1.97 52 2.05 60 4 100 3.94 50 1.97 52 2.05 120 5 200 7.87 25 0.98 70 2.76 104 NOTE Dimension Z assumes that the drives are mounted side-by-side with no clearance. Typical drive heat losses are 3% of operating load conditions. Above are guidelines only and the operating ambient temperature of the drive MUST be maintained at all times.

Protective Earth (PE) Connection Grounding Guidelines The ground terminal of each Optidrive should be individually connected DIRECTLY to the site ground bus bar (through the filter if installed). Optidrive ground connections should not loop from one drive to another, or to, or from any other equipment. Ground loop impedance must confirm to local industrial safety regulations. To meet UL regulations, UL approved ring crimp terminals should be used for all ground wiring connections. The drive Safety Ground must be connected to system ground. Ground impedance must conform to the requirements of national and local industrial safety regulations and/or electrical codes. The integrity of all ground connections should be checked periodically. Protective Earth Conductor The Cross sectional area of the PE Conductor must be at least equal to that of the incoming supply conductor. Safety Ground This is the safety ground for the drive that is required by code. One of these points must be connected to adjacent building steel (girder, joist), a floor ground rod, or bus bar. Grounding points must comply with national and local industrial safety regulations and/or electrical codes. Motor Ground The motor ground must be connected to one of the ground terminals on the drive. Ground Fault Monitoring As with all inverters, a leakage current to earth can exist. The Optidrive is designed to produce the minimum possible leakage current whilst complying with worldwide standards. The level of current is affected by motor cable length and type, the effective switching frequency, the earth connections used and the type of RFI filter installed. If an ELCB (Earth Leakage Circuit Breaker) is to be used, the following conditions apply: �� A Type B Device must be used. �� The device must be suitable for protecting equipment with a DC component in the leakage current. �� Individual ELCBs should be used for each Optidrive. M

www.invertekdrives.com Shield Termination (Cable Screen) The safety ground terminal provides a grounding point for the motor cable shield. The motor cable shield connected to this terminal (drive end) should also be connected to the motor frame (motor end). Use a shield terminating or EMI clamp to connect the shield to the safety ground terminal. 4.3. Incoming Power Connection 4.3.1. Cable Selection �� For 1 phase supply, the mains power cables should be connected to L1/L, L2/N. �� For 3 phase supplies, the mains power cables should be connected to L1, L2, and L3. Phase sequence is not important. �� For compliance with CE and C Tick EMC requirements, refer to section 4.9. EMC Compliant Installation on page 15. �� A fixed installation is required according to IEC61800-5-1 with a suitable disconnecting device installed between the Optidrive and the AC Power Source. The disconnecting device must conform to the local safety code / regulations (e.g. within Europe, EN60204-1, Safety of machinery). �� The cables should be dimensioned according to any local codes or regulations. Maximum dimensions are given in section 9.2. Rating Tables. 4.3.2. Fuse / Circuit Breaker Selection �� Suitable fuses to provide wiring protection of the input power cable should be installed in the incoming supply line, according to the data in section 9.2. Rating Tables. The fuses must comply with any local codes or regulations in place. In general, type gG (IEC 60269) or UL type J fuses are suitable; however in some cases type aR fuses may be required. The operating time of the fuses must be below 0.5 seconds. �� Where allowed by local regulations, suitably dimensioned type B MCB circuit breakers of equivalent rating may be utilised in place of fuses, providing that the clearing capacity is sufficient for the installation. �� The maximum permissible short circuit current at the Optidrive Power terminals as defined in IEC60439-1 is 100kA. 4.3.3. Optional Input Choke �� An optional Input Choke is recommended to be installed in the supply line for drives where any of the following conditions occur: o The incoming supply impedance is low or the fault level / short circuit current is high. o The supply is prone to dips or brown outs. o An imbalance exists on the supply (3 phase drives). o The power supply to the drive is via a busbar and brush gear system (typically overhead Cranes). �� In all other installations, an input choke is recommended to ensure protection of the drive against power supply faults. Part numbers are shown in the table. Supply Frame Size AC Input Inductor 230 Volt 1 Phase 1 OPT-2-L1016-20 2 OPT-2-L1025-20 3 N/A 400 Volt 3 Phase 1 OPT-2-L3006-20 2 OPT-2-L3010-20 3 OPT-2-L3036-20 4 OPT-2-L3050-20 5 OPT-2-L3090-20 4.4. Motor Connection �� The drive inherently produces fast switching of the output voltage (PWM) to the motor compared to the mains supply, for motors which have been wound for operation with a variable speed drive then there is no preventative measures required, however if the quality of insulation is unknown then the motor manufacturer should be consulted and preventative measures may be required. �� The motor should be connected to the Optidrive U, V, and W terminals using a suitable 3 or 4 core cable. Where a 3 core cable is utilised, with the shield operating as an earth conductor, the shield must have a cross sectional area at least equal to the phase conductors when they are made from the same material. Where a 4 core cable is utilised, the earth conductor must be of at least equal cross sectional area and manufactured from the same material as the phase conductors. �� The motor earth must be connected to one of the Optidrive earth terminals. �� Maximum permitted motor cable length for all models: 100 metres shielded, 150 metres unshielded. �� Where multiple motors are connected to a single drive using parallel cables, an output choke must be installed.

Optional Brake Resistor Optidrive E3 Frame Size 2 and above units have a built in Brake Transistor. This allows an external resistor to be connected to the drive to provide improved braking torque in applications that require this. The brake resistor should be connected to the “+” and “BR” terminals as shown. The voltage level at these terminals may exceed 800VDC. Stored charge may be present after disconnecting the mains power. Allow a minimum of 10 minutes discharge after power off before attempting any connection to these terminals. Suitable resistors and guidance on selection can be obtained from your Invertek Sales Partner. Dynamic Brake Transistor with Thermal Overload Protection L1/L K1 ODE-3 DC+ K1 - Main Contractor Thermal Overload / Brake Resistor with internal Over Temperature switch BR L2/N L3 Dlx + 24 VDC ODE-3 Optional wiring It is highly recommended to equip the drive with a main contractor and provide and use an additional thermal overload protection for braking resistor. The contractor should be wired so that it opens in case the resistor overheats, otherwise the drive will not be able to interrupt the main supply if the brake chopper remains closed (short-circuited) in a faulty situation. It is also recommended to wire the thermal overload protection to a digital input of the drive as an External Trip. The voltage level at these terminals may exceed 800VDC. Stored charge may be present after disconnecting the mains power. Allow a minimum of 5 minutes discharge after power off before attempting any connection to these terminals.

www.invertekdrives.com 7. Analog and Digital Input Macro Configurations 7.1. Overview Optidrive E3 uses a Macro approach to simplify the configuration of the Analog and Digital Inputs. There are two key parameters which determine the input functions and drive behaviour: P-12 Selects the main drive control source and determines how the output frequency of the drive is primarily controlled. P-15 Assigns the Macro function to the analog and digital inputs. Additional parameters can then be used to further adapt the settings, e.g. P-16 Used to select the format of the analog signal to be connected to analog input 1, e.g. 0 – 10 Volt, 4 – 20mA. P-30 Determines whether the drive should automatically start following a power on if the Enable Input is present. P-31 When Keypad Mode is selected, determines at what output frequency / speed the drive should start following the enable command, and also whether the keypad start key must be pressed or if the Enable input alone should start the drive. P-47 Used to select the format of the analog signal to be connected to analog input 2, e.g. 0 – 10 Volt, 4 – 20mA. 7.2.

Fire Mode The Fire Mode function is designed to ensure continuous operation of the drive in emergency conditions until the drive is no longer capable of sustaining operation. The Fire Mode input may be a normally open (Close to Activate Fire Mode) or Normally Closed (Open to Activate Fire Mode) according to the setting of P-30 Index 2. In addition, the input may be momentary or maintained type, selected by P-30 Index 3. This input may be linked to a fire control system to allow maintained operation in emergency conditions, e.g. to clear smoke or maintain air quality within that building. The fire mode function is enabled when P-15 = 15, 16 or 17, with Digital Input 3 assigned to activate fire mode. Fire Mode disables the following protection features in the drive:  (Heat-sink Over-Temperature),  (Drive Under Temperature), L (Faulty Thermistor on Heat-sink),  (External Trip),   (4-20mA fault),  (Phase Imbalance), L (Input Phase Loss Trip), C (Communications Loss Trip), . (Accumulated overload Trip). The following faults will result in a drive trip, auto reset and restart: Vl (Over Voltage on DC Bus), Vl (Under Voltage on DC Bus),   (Fast Over-current Trip),  (Instantaneous over current on drive output),  (Drive output fault, Output stage trip).

Single Phase Operation of Three Phase Drives All drive models intended for operation from three phase mains power supply (e.g. model codes ODE-3-xxxxxx-3xxx) may be operated from a single phase supply at up to 50% of maximum rated output current capacity. In this case, the AC power supply should be connected to L1 (L) and L2 (N) power connection terminals only. 9.4. Additional Information for UL Compliance Optidrive E3 is designed to meet the UL requirements. For an up to date list of UL compliant products, please refer to UL listing NMMS.E226333. In order to ensure full compliance, the following must be fully observed. Input Power Supply Requirements Supply Voltage 200 – 240 RMS Volts for 230 Volt rated units, + /- 10% variation allowed. 240 Volt RMS Maximum. 380 – 480 Volts for 400 Volt rated units, + / - 10% variation allowed, Maximum 500 Volts RMS. Imbalance Maximum 3% voltage variation between phase – phase voltages allowed. All Optidrive E3 units have phase imbalance monitoring. A phase imbalance of > 3% will result in the drive tripping. For input supplies which have supply imbalance greater than 3% (typically the Indian sub-continent & parts of Asia Pacific including China) Invertek Drives recommends the installation of input line reactors.

Mechanical Installation Requirements All Optidrive E3 units are intended for indoor installation within controlled environments which meet the condition limits shown in section 9.1. Environmental. The drive can be operated within an ambient temperature range as stated in section 9.1. Environmental. For IP20 units, installation is required in a pollution degree 1 environment. Frame size 4 drives must be mounted in an enclosure in a manner that ensures the drive is protected from 12.7mm (1/2 inch) of deformation of the enclosure if the enclosure impacted. Electrical Installation Requirements Incoming power supply connection must be according to section 4.3. Incoming Power Connection. Suitable Power and motor cables should be selected according to the data shown in section 9.2. Rating Tables and the National Electrical Code or other applicable local codes. Motor Cable 75°C copper stranded or similar (90°C for enclosed Nema 4X type drives). Power cable connections and tightening torques are shown in sections 3.3. Mechanical Dimensions and Mounting – IP20 Open Units. Integral Solid Sate short circuit protection does not provide branch circuit protection. Branch circuit protection must be provided in accordance with the national electrical code and any additional local codes. Ratings are shown in section 9.2. Rating Tables. Transient surge suppression must be installed on the line side of this equipment and shall be rated 480Volt (phase to ground), 480 Volt (phase to phase), suitable for over voltage category iii and shall provide protection for a rated impulse withstand voltage peak of 4kV. UL Listed ring terminals / lugs must be used for all bus bar and grounding connections. General Requirements Optidrive E3 provides motor overload protection in accordance with the National Electrical Code (US). • Where a motor thermistor is not fitted, or not utilised, Thermal Overload Memory Retention must be enabled by setting P-50 = 1. • Where a motor thermistor is fitted and connected to the drive, connection must be carried out according to the information shown in section 4.8.2. Motor Thermistor Connection. Technical Data 9

Drives with an EMC filter have an inherently higher leakage current to Ground (Earth). For applications where tripping occurs the EMC filter can be disconnected (on IP20 units only) by completely removing the EMC screw on the side of the product. Remove the screw as indicated right. The Optidrive product range has input supply voltage surge suppression components fitted to protect the drive from line voltage transients, typically originating from lightning strikes or switching of high power equipment on the same supply. When carrying out a HiPot (Flash) test on an installation in which the drive is built, the voltage surge suppression components may cause the test to fail. To accommodate this type of system HiPot test, the voltage surge suppression components can be disconnected by removing the VAR screw After completing the HiPot test, the screw should be replaced and the HiPot test repeated. The test should then fail, indicating that the voltage surge suppression components are once again in circuit. 9 Technical Data
