Emission And Immunity Levels - WEG CFW701 User Manual

3. Shielded output cables (motor cables) and connect the shield at both ends (motor and
inverter) with a low impedance connection for high frequency. Use PCSx-01 kit supplied
with frame sizes A, B and C inverters. For frame sizes B and C with degree of protection
IP55, use the PCSC-03 shield kit. For frame sizes D and E inverters use the clamps supplied
with the product. Ensure good contact between the cable shield and the clamps. Refer to
