Main distribution frame

3.9 Main distribution frame
The integral main distribution frame is the connecting point for the cable network to the trunk
and to the extensions. Connection is implemented by means of screw connectors and terminal
blocks. The terminal blocks can be disconnected from the system for easy assembly/disassem-
bly.
The modules for system expansions and the function-expansion modules have their own dis-
tributor portions in the form of PC board connectors for the terminal blocks. The terminal blocks
required for wiring are supplied with the respective modules.
