In cases where the cable length is >500mm or there are high level EMC requirements, observe the notes given below.
Use a shielded cable for DC-Bus link connection. The shield should be connected on both ends. The wires for DC+ and DC- (BRC wire with KCM-S as well) should be passed with one winding through a ferrite core close to the KCM (see graphics below).
The ground wire should be passed through a ferrite core close to the KCM as well.
