5.2.4 EMC Compliant Electrical Installation
General points to be observed to ensure EMC-correct electrical installation.
•
Use only screened/armoured motor cables and screened/armoured control cables.
•
Connect the screen to earth at both ends.
•
Avoid installation with twisted screen ends (pigtails), since this ruins the screening 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 frequency converter.
•
Use starwashers and galvanically conductive installation plates.
•
Do not use unscreened/unarmoured motor cables in the installation cabinets.
