Shielding for the cables
•
Shield the data cables and connect the shield at both ends.
•
Shield the analog cables and connect the shield at one end, e.g. on the drive unit.
•
Always apply large-area connections between the cable shields and the shielding bus at
the cabinet inlet and make the contact with clamps.
•
Feed the connected shield through to the module without interruption.
•
Use braided shields, not foil shields.
Line and signal filter
•
Use only line filters with metal housings
•
Connect the filter housing to the cabinet chassis using a large-area low-HF-impedance
connection.
•
Never fix the filter housing to a painted surface.
•
Fix the filter at the control cabinet inlet or in the direction of the source.
