10.3. Input Power Supply Requirements
Supply Voltage
200 – 240 RMS Volts for 230 Volt rated units, + /- 10% variation allowed.
380 – 480 Volts for 400 Volt rated units, + / - 10% variation allowed.
500 – 600 Volts for 600 Volt rated units, + / - 10% variation allowed.
Imbalance
Maximum 3% voltage variation between phase – phase voltages allowed.
All Optidrive P2 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. Alternatively, the drives can be
operated as a single phase supply drive with 50% derating.
Frequency
50 – 60Hz + / - 5% Variation.
10.4. Additional Information for UL Approved Installations
Optidrive P2 is designed to meet the UL requirements. In order to ensure full compliance, the following must be fully observed.

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.
Incoming power supply connection must be according to section
4.3. Incoming Power Connection.
All Optidrive P2 units are intended for indoor installation within controlled environments which meet the condition limits shown in section
Branch circuit protection must be installed according to the relevant national codes. Fuse ratings and types are shown in section
Output Power and Current Ratings.
Suitable Power and motor cables should be selected according to the data shown in section
10.2. Input/Output Power and Current Ratings.
Power cable connections and tightening torques are shown in section
3.4. Installation Following a Period of Storage.
Optidrive P2 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 P4-12 = 1.
Where a motor thermistor is fitted and connected to the drive, connection must be carried out according to the information shown in section
4.7. Motor Terminal Box Connections.
For Canadian Installations : transient surge suppression shall be installed on the line side of this equipment and shall be rated as shown below,
suitable for over voltage category III and shall provide protection for a rated impulse withstand voltage peak of 2.5kV.

10.5. Derating Information
Derating of the drive maximum continuous output current capacity is require when:
Operating at ambient temperature in excess of 40°C / 104°F for enclosed drives (Non UL Approved).
Operating at Altitude in excess of 1000m/ 3281 ft.
Operation with Effective Switching Frequency higher than 8kHz for IP20 models and 4kHz for IP55/IP66 models.
The following derating factors should be applied when operating drives outside of these conditions.
