Integration Of The Components In The Cabinet - Siemens SINAMICS G120 Applications Manual

Integration of the components in the cabinet

Because of possible vibration stress, a Control Unit should not be directly plugged onto a
PM240-2 Power Module but should be installed separately in a control cabinet.
An exception to this recommendation are the CU230P-2 and the CU240-2 when used in
combination with Power Modules of frame size FSA, FSB, or FSC.
See "System configuration for marine applications (Page 21)").
CU230P-2, CU240E-2, CU250S-2 Control Units are installed offset off the Power Module
using the "Control Unit Adapter Kit" CUA20.
The "Control Unit Adapter Kit" CUA20 comprises an adapter, which is plugged onto the
Power Module, and a base that is mounted next to the Power Module in the cabinet. The
Control Unit is then plugged onto this base.
When installing an S120 converter (in the Blocksize format), a Control Unit Adapter CUA31
or CUA32 is directly plugged onto a PM240-2 Power Module. A higher-level control module
(e.g. CU320-2) is connected using "DRIVE-CLiQ".
