12.4.4 Shielding
• Metal cable glands ensure a connection of shield and housing over a large area.
• In case of contactors and terminals in shielded cables,
– connect the shields of all cables and connect these over a large area with the
mounting platform.
• In case of supply system cables between radio interference suppression filter and
drive controller in excess of 300 mm (11.8"):
– Shield supply system cable.
– Apply the shield of the supply system cable directly at the drive controller / on the
regenerative power supply unit and the radio interference suppression filter and
connect it over a large area to the mounting plate.
• Shielding the control cables:
– Connect the shields with the shield connections by the shortest possible route.
12.4.5 Grounding
• Ground all conductive metal components (regenerative power supply unit, drive con-
troller, radio interference suppression filter) by using the appropriate cables from a
central grounding point (PE busbar).
• Comply with the minimum cross sections defined in the safety regulations:
– For EMC purposes, it is not the cable cross section but the surface of the cable
and the connection over a wide area that are important.
