1. VFD cable earthing in converter side: use EMC screen clip or useful steel strip to create a solid 360° contact between the shield and EMC screen bus bar. The armor should be made into a pigtail and connected to PE bus as well as the three grounding cores.
2. VFD cable earthing in motor side: cable should be taken off the insulation after going into the motor box and the screen and armor should screwed  into a pigtail together, this pigtail should connect to PE bar as well as 3 grounding cores. The installation must be sure that interference current can find a continuous, low-inductance path without interruptions or weak points throughout the shield between motor and converter or it is far less             effective in preventing interference currents from spreading beyond the drive system.

最好选用EMC CABLE GLAND,有的OWNER会要求。
