Fitting the CU to the PM

Fitting the Control Unit to the Power Module
The inverter is delivered as two separate components - the Power Module (PM) and the
Control Unit (CU). The CU must be fitted to the PM prior to any further commissioning taking
place.
Seals fitted correctly
It is important that when assembling the Power Module and the Control Unit that all the
seals are fitted correctly to ensure IP65 rating.
TN and TT mains supplies
The SINAMICS PM250D Power Module with the Class A integrated mains filter is only
suitable for operation on TN and TT mains supplies.
The CU is fitted to the PM as shown in the diagram below.
