Example: CU230P-2 PN Control Unit

The CU230P-2 Control Units are designed for drives with integrated technological functions for pump, fan and compressor applications. The I/O interface, the fieldbus interfaces and the additional software functions optimally support these applications.

Note:

Shield plates and shield connection kits are available. These can be used in the wiring installation for the Control Units and PM230/PM240 Power Modules to ensure that it complies with EMC guidelines.
For further information, see Shield connection kits and shield plates for Control Units and Power Modules in section Supplementary system components.

PM330 Power Modules are supplied with the accessories needed to create an EMC-compliant wiring installation for Control Units and Power Modules. The Control Unit mounting surface on the Power Modules has mounting slots for shielding terminals.
