2.2 Installing the SIMOTION D4x5-2
The D425-2 and D435-2 control units do not have any cooling fins on the rear side of the
module so that the spacers can be removed if required.
As the D445-2 and D455-2 control units have cooling fins, the spacers can be removed
when external air cooling is used.
With external air cooling, the cooling fins are outside of the control cabinet. A seal is required
so that the control unit can be hermetically mounted in the rear cabinet panel.
The fan/battery module can be mounted or replaced without having to disassemble the
control unit. As the control unit is similar to the SINAMICS S120 family with regard to
installation, please also refer to the information in the SINAMICS manuals.
The same installation instructions apply for the SIMOTION D4x5-2/CX32-2 control units as
for the SINAMICS S120 CU320-2 control units with regard to EMC.
For further information, see the SINAMICS manuals.
Mounting and installation aids
The control unit is designed for mounting in a control cabinet (IP20 degree of protection). All
versions of SIMOTION D4x5-2 are supplied with pre-assembled spacers for installation on
the wall of the control cabinet. The spacers can be removed if necessary.
