Additional Information for UL Compliance
Optidrive E2 is designed to meet the UL requirements. In order to ensure full compliance, the following must be fully observed.
For an up to date list of UL compliant products, please refer to UL listing NMMS.E226333
The drive can be operated within an ambient temperature range as stated in section 9.1
For IP20 units, installation is required in a pollution degree 1 environment
For IP66 (Nema 4X) units, installation in a pollution degree 2 environment is permissible
UL Listed ring terminals / lugs must be used for all bus bar and grounding connections
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 E2 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.

All the drives in the above table are suitable for use on a circuit capable of delivering not more than the above
specified maximum short-circuit Amperes symmetrical with the specified maximum supply voltage.
Motor Cable
75°C Copper must be used
Fusing
UL Class T Fuses must be used
Incoming power supply connection must be according to section 4.3
All Optidrive E2 units are intended for indoor installation within controlled environments which meet the condition limits shown in section
9.1
Branch circuit protection must be installed according to the relevant national codes. Fuse ratings and types are shown in section 9.2
Suitable Power and motor cables should be selected according to the data shown in section 9.2
Power cable connections and tightening torques are shown in section 3.1
Optidrive E2 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 7.5
