IP20, 380–480 V, 30–315 kW (40–450 hp)
6.3 EMC-compliant Electrical Installation
To ensure EMC-correct electrical installation, observe the following:
Use only shielded/armored motor cables and shielded/armored control cables.
Ground the shield at both ends.
Avoid installation with twisted shield ends (pigtails), because it reduces the shielding effect at high frequencies. Use the cable
clamps provided.
Ensure the same potential between the drive and the ground potential of PLC.
Use star washers and galvanically conductive installation plates.
