Section 5 Mounting
CP-C MM messaging module and CP-A CM control module
While the CP-C MM messaging module is plugged on a CP-C switch-mode power
supply unit, the CP-A CM control module must be mounted to a CP-C RU
redundancy unit.
The modules are attached to the front side of the power supply unit or the
redundancy unit. The embossed front film at the power supply unit or the
redundancy unit is thus penetrated by the locking latches and the plug contacts.

To remove the CP-C MM and CP-A CM modules, carefully press and tilt them
upwards. Pull the module downwards to unlock the locking latch and remove the
CP-C MM or the CP-A CM module from the power supply unit or the redundancy
unit, respectively.
