5.3.2. Wiring the master unit, overview
The master unit requires the following wirings:
• secondary circuits of the current transformers of the
switchgear
• trip circuits of the circuit-breakers
• alarm circuits
• auxiliary supply circuits
• protective earthing
• connections to slave units (data communication and
possibly separate auxiliary supply)
• connections to other master units (if the system
comprises several communicating master units).
The five first mentioned connections are described in the next
sub-sections. The connections to slave units and other master
units will be described in sections 5.4 and 5.7 respectively.
See the example in Figure 5.3.2-1, and the block diagram in
Figure 5.3.7-1.
