Cable length
The maximum cable length is 100 m (328 ft). Screened cables must be used.
The PWM output switching from any inverter using a long motor cable can cause an
increase in the voltage at the motor terminals, depending on the cable length and
inductance. The rise time and peak voltage can affect the service life of the motor. Flygt
recommends using an output choke for motor cable lengths of 50 m or more to ensure
good motor service life.
For UL-compliant installation, use copper wire with a minimum insulation temperature
rating of 75°C (167°F). When using fuses, the type must be Class CC or Class J
