Appendix C: Operation without a Controller - Alarm Wiring
Each converter shelf provides alarm contact closures for Power Major and Power Minor independently
of a controller. Wire these relays into the alarm network in deployments where a controller is not
utilized. When a controller is installed then an alarm cable can be attached to the controller – see the
Connect Office Alarms section.
Converter Shelf Alarm Card State Table
This section shows Alarm and LED response for the Alarm Card LEDs and Relays:
The Converter Shelf contains a pair of A bus feeds and a pair of B bus feeds. The use of dual A and B
feeds is to not exceed the 48 AMPS L2 input current per feed. The A bus feeds are designated A1 - 6 and
A9 - 12, and power shelf slots 1 - 6 (left side) and 7 - 12 (right side) respectively. The B bus feeds are also
designated in an identical fashion. The alarm card monitors the - 48v on each of these four feeds, and
asserts alarms and indicators - Table 11.
