1.3.7 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 cable clamps instead.
