Supply system lead and motor cable
Project Planning
Motor feeder
length The maximum motor feeder length is dependent on:
• cable type,
• voltage drop in the cable,
• set PWM frequency.
• Use of an output filter (not permitted with 230 V units)
1
1 The limit values in the tables do not apply if you are using an output filter. The motor feeder length is then
solely limited by the voltage drop on the motor feeder.

You should not use an earth-leakage circuit breaker with long motor leads. The earth-
leakage currents caused by cable capacitance may cause mis-tripping.
