Connecting the protective conductor

The SINAMICS DCM Control Module has connecting lugs at the side of both cradles to
connect the protective conductor.
In the delivery condition (both cradles assembled), the protective conductor should be
connected to one of these lugs. Minimum cross section 4 mm
If the two cradles are installed separately, then a protective conductor must be connected to
both cradles.
Note
If the unit is stored for a longer period of time, a layer of corrosion can form on the bare
metal surfaces of the cradles. Before connecting the protective conductor, this must be
removed from the connection lugs.
