Electric motors R/C combination from each motor winding to earth.
Frequency converter Inlet filter in the voltage supply of the frequency converter
Motor control lines shielded and installed separately from other
cables and/or output filter for motor cables.
Extensive contact of the frequency converter housing to the rear
