Note
The maximum motor cable length stated applies to using a screened motor cable. When using an unscreened cable, the maximum
cable length limit is increased by 50%. When using the Invertek Drives recommended output choke, the maximum cable length limited
can 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 wir4 with a minimum insulation temperature rating of 75°C. When using fuses type should
be Class CC or Class J
