Installation of the Power Modules
Use an unshielded cable for the line supply connection for Power Modules with an
integrated filter.
If you connect the Power Module to the line supply via an external filter, use a
shielded cable between the line filter and the Power Module.
The EMC-compliant installation of the Power Modules is shown in the following
diagram using two examples.
1 Line connection
2 Motor connection
3 Line supply cable (unshielded)
4 Motor connection cable (unshielded)
5 Cable shield
1. Shielding with a shield plate
- There are shield connection kits for all sizes of Power Modules. Shield
connection kits for sizes FSD...FSF must be ordered separately. Connect
the cable shields to the shield plate over a large area with shield clamps.
2. Shielding without a shield plate
- EMC-compliant shielding can also be implemented without using a shield
plate. In this case, you must ensure that the cable shields are connected to
the ground potential over a large area.
