Cable shielding
The shielding bus should be connected to the control cabinet enclosure in a manner allowing
good conductance (large-area contact) and must be situated as close as possible to the cable
inlet. The cable insulation must be removed and the cable clamped to the shielding bus (high-
frequency clamp) or secured using cable ties. Care should be taken to ensure that the connection
allows good conductance.

Connection of shielding bus
The shielding bus must be connected to the PE busbar.
If shielded cables have to be interrupted, the shield must be continued via the corresponding
connector housing. Only suitable connectors may be used for this purpose.
