13.5. Additional Information for UL Approved Installations
Optidrive HVAC is designed to meet the UL requirements. 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 HVAC 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
Short Circuit Capacity Voltage Rating Min kW (HP) Max kW (HP) Maximum supply short-circuit current
230V 0.37 (0.5) 18.5 (25) 5kA rms (AC)
230V 22 (30) 75 (100) 10kA rms (AC)
400 / 460V 0.75 (1) 37 (50) 5kA rms (AC)
400 / 460V 45 (60) 132 (200) 10kA rms (AC)
400 / 460V 160 (250) 250 (350) 18kA rms (AC)
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
All Optidrive HVAC units are intended for indoor installation within controlled environments which meet the condition limits in section 13.1
Branch circuit protection must be installed according to the relevant national codes. Fuse ratings and types are shown in section 13.4
Suitable Power and motor cables should be selected according to the data shown in section 13.4
Power cable connections and tightening torques are shown in section 3
Optidrive HVAC provides motor overload protection in accordance with the National Electrical Code (US).
