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.
•
Connect the shield to ground at both ends.
•
Avoid installation with twisted shield ends (pigtails), since this ruins the shielding effect at high frequencies. Use
the cable clamps provided instead.
•
It is important to ensure good electrical contact from the installation plate through the installation screws to the
metal cabinet of the adjustable frequency drive.
•
Use starwashers and galvanically conductive installation plates.
•
Do not use shielded/armored motor cables in the installation cabinets.
