5.2.5 EMC Compliant Electrical Installation
General points to be observed to ensure EMC-correct electrical installation.
•
Use only shielded/armored motor cables and shielded/armored control cables.
•
Connect the screen to ground at both ends.
•
Avoid installation with twisted screen ends (pigtails), since this ruins the screening eect 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 star washers and galvanically conductive installation plates.
•
Do not use unshielded/unarmored motor cables in the installation cabinets.
