5.2.5 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.

•

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.
