Proper termination requires the cable to be terminated at both the drive end at the motor end of the cable.
Vfd cable termination kits.
Both ends of the vfd cable need to be terminated in order to allow the high frequency common mode current to flow back through the shield to the drive 1.
Both methods are described below.
Non armored vfd cable termination kits components of a termination kit are available through various distributors.

As the original developer of high quality vfd cable belden knows how to deliver superior electrical performance and reliability even in the most demanding industrial environments.
The termination kit provides a low impedance path at high frequency for common mode current created by the drive to return to the inverter via the shield and minimizes potential problems.
Southwire s variable frequency drive shield.
Used to properly terminate the helically applied copper tape shield of vfd cable constructions.
Variable frequency ac motor drive output cables are subject to harsh operating settings characterized by high voltage spikes high noise levels and adverse environmental conditions.
