Shielding with shield plate: Shield connection kits are available for all Power
Module frame sizes (you will find more information in
Catalog D11.1). The cable shields must be
connected to the shield plate through the greatest
possible surface area using shield clamps.
Shielding without shield plate: EMC-compliant shielding can also be implemented
without an optional shield plate. In this case, you
must ensure that the cable shields are connected to
the ground potential through the largest possible
surface area.
Braking resistor connection: The braking resistor is connected using a shielded
cable. Using a clamp, the shield should be
connected to the mounting plate or to the shield
plate through a good electrical connection and
through the largest possible surface area.
