3.2.5 EMC-compatible Electrical Installation

General points to be observed to ensure EMC-compatible electrical installation.
•
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 this reduces the shielding effect at high frequencies.
Use the cable clamps provided.
•
Ensure the same potential between drive and ground potential of PLC.
•
Use starwashers and galvanically grounding plates.
