Figure 35 Alarm Card Pin Out; Figure 36 Alarm Card Cables - ABB CPS2400U Product Manual

Alarm Card Office Alarms
Each Shelf provides alarm contact closures for Power Major and Power Minor. Wire these relays into the
alarm network if desired.
Systems equipped with a controller provide all alarms via the controller alarm connector and require no
office alarm wiring to alarm cards.
Inter-Shelf Signal Cables are only required between Fan Shelves and the adjacent Converter Shelf in
systems without a Controller.
