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.
Vfd cable termination kits.
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.
Non armored vfd cable termination kits components of a termination kit are available through various distributors.
Proper termination requires the cable to be terminated at both the drive end at the motor end of the cable.
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.
These shields may be terminated with either a cable gland or if used in conduit a termination kit.
