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.
•
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 provide-
dinstead.
•
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.
