filter and line reactor
The cabling should be kept as short as possible. The line supply cable
to the radio interference suppression filter must be routed separately
away from other cables (zone concept!).
The motor must be connected using a shielded cable! The shield has to
be connected through the largest possible surface area at the motor
and the inverter.
