Installation

■

EMC-correct electrical installation

General points to be observed to ensure

EMC-correct electrical installation.

-

Use only shielded/armoured motor cables and

shielded/armoured control cables.

-

Connect the screen to ground at both ends.

-

Avoid installation with twisted shield ends (pigtails),

since this ruins the shielding 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 variable frequency drive.

-

Use starwashers and galvanically conductive

installation plates.

-

Do not use unshielded/unarmoured motor

cables in the installation cabinets.

The illustration below shows EMC-correct electrical

installation, in which the variable frequency

drive has been fitted in an installation cabinet

and connected to a PLC.
