NOTE:
Ratings shown above apply to 40°C Ambient temperature. For derating information, refer to section
Operation with single phase supply is possible, with 50% derating of the output current capacity.
The maximum motor cable length stated applies to using a shielded motor cable. When using an unshielded cable, the maximum
cable length limit may be increased by 50%. When using the Invertek Drives recommended output choke, the maximum cable
length may be increased by 100%.
The PWM output switching from any inverter when used with a long motor cable length can cause an increase in the voltage at the
motor terminals, depending on the motor cable length and inductance. The rise time and peak voltage can affect the service life of the
motor. Invertek Drives recommend using an output choke for motor cable lengths of 50m or more to ensure good motor service life.
For UL compliant installation, use Copper wire with a minimum insulation temperature rating of 70°C, UL Class CC or Class J Fuses.
