Emc-Correct Installation With Rfi-Filter - Danfoss VLT MICRO Manual

EMC correct installation with RFI-filter
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
(pig-tails), since this ruins the screening
effect at high frequencies. Use cable
clamps instead. from the installation plate
through the installation screws to the metal
cabinet of the AC drive.
- Use starwashers and galvanically
conductive installation plates.
- Do not use unscreened/unarmoured motor
cables in the installation cabinets.
The illustration below shows EMC-correct
electrical installation, in which the AC drive has
