MiCOM P632
Designs

The P632 is available in a surface-mounted and a flush-mounted case. Depending on the connection type – pin-terminal or ring-terminal connection – the case sizes differ. The location diagrams (Chapter “Location and Connection Diagrams”) show the available combinations of case widths and connection types.

Electrical connections are made via plug-in threaded terminal blocks. The threaded terminal blocks in the surface-mounted case are accessible from the front of the device after unscrewing the crosshead screws on the sides (see Fig. 4-1, ➀) and removing the local control panel. The local control panel can then be secured by inserting the tabs in the slots in the left side wall (see Fig. 4-1, ➁). The flush-mounted case is connected at the back of the case.

The local control panel is connected to processor module P by a plug-in connecting cable. Do not bend the connecting cable! Secure the local control panel by inserting it in the slots provided on the left.

graphics/symbols/Warning.png WARNING

The secondary circuit of live system current transformers must not be opened! If the secondary circuit of a live CT is opened, there is the danger that the resulting voltages will endanger personnel and damage the insulation.

graphics/symbols/Warning.png WARNING

For pin-terminal connection devices, the terminal block for system current transformer connection is not a shorting block! Therefore always short-circuit the system current transformers before loosening the threaded terminals.
