Motor choke
Only necessary from a shield capacity of >5 nF / approx. 25 m motor cable.
Ferrite rings
In case of HF interference coupling on Sensor systems, slide ferrite rings over the motor cable.
Shield connection
Flat connection at the control cabinet input or machine/vehicle frame.
Flat or shortest possible connection on the motor side.
If the motor cables are long, connect the motor cable shields to earth (mounting frame)
several times (e.g. earth connection every 2 metres).
