6.2 Installation types
Prerequisite
The Control Unit is installed in a control cabinet along with the SINAMICS components.
The following prerequisites must be met to install a Control Unit:
● The control cabinet has been installed and wired.
● SINAMICS components should already have been installed and wired (for lateral
mounting).
● Components and tools are available.
Note
The procedures described below for mounting the Control Unit refer to the delivery
condition of the Control Unit: The upper clip is pulled in and the spacers are mounted
(see figure below).
Designs
The Control Unit is compatible with the SINAMICS S120 in booksize format. There are two
possible mounting methods:
● Mounting on the rear wall of the control cabinet
● Lateral mounting on the SINAMICS S120 Line Module
In this type of mounting, the Control Unit is attached to the side wall of the Line Module in
the control cabinet.
As the design of the Control Unit is based on that of the SINAMICS S120 family, please
observe these notes and the corresponding reference documents.
Mounting aids
The Control Unit is designed for mounting in a control cabinet (IP 20 degree of protection in
accordance with general conditions).
Note
Exception: NCU 710.2 and NCU 720.2 have no cutouts for lateral mounting on the
SINAMICS drive line-up.
