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.
Step Action
1. Attach the required alarm leads to the office alarm screw terminals (TB1 on the alarm card) as
designated.
Figure 34 Office Alarm Pin Outs - Alarm Cards
2. Reinstall Alarm card and close distribution door.
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 A
1-6
and A
9-12
, 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.
