4.12 EMC-Correct Electrical Installation

General points to observe to ensure EMC-correct electrical
installation.

•

Use only screened/armoured motor cables and
screened/armoured control cables.

•

Connect the screen to ground at both ends.

•

Avoid installation with twisted screen ends
(pigtails), since this ruins the screening effect at
high frequencies. Use cable clamps 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.

Illustration 4.9

shows EMC-correct electrical installation, in

which the frequency converter has been fitted in an instal-
lation cabinet and connected to a PLC.
