3.2 Installing the SIMOTION D4x5-2
3.2.1 Installing the SIMOTION D4x5-2
Requirement
The Control Unit is installed in a control cabinet along with the SINAMICS components.
The following requirements must be met for installing a Control Unit:
● The control cabinet has been installed and wired.
● The SINAMICS components should already have been installed and wired.
● Components and tools are available.
Note
The components must be protected against conductive contamination, e.g. by installing them
in a control cabinet with degree of protection IP54 according to IEC 60529 or NEMA 12.
If conductive contamination can be excluded at the installation site, a lower degree of cabinet
protection may be permitted.
Designs
A D4x5‑2 Control Unit is designed similar to a SINAMICS S120 booksize unit. It is mounted
directly on the wall of the control cabinet, whereby a distinction is made between the following
designs.
● Mounting the SIMOTION D4x5-2 with spacers
● Mounting the SIMOTION D425-2 and D435-2 without spacers
● Mounting the SIMOTION D445-2 and D455-2 without spacers (external air cooling)
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.
