3.2.5 EMC-Correct Electrical Installation
General points to be observed to ensure EMC-correct electrical installation.
•
Use only screened/armoured motor cables and screened/armoured control cables.
•
Ground the screen at both ends.
•
Avoid installation with twisted screen ends (pigtails), because this reduces the screening effect at high frequencies.
Use the cable clamps provided.
•
Ensure the same potential between drive and ground potential of PLC.
•
Use starwashers and galvanically conductive installation plates.
