External Alarm Connections
External alarm wiring is made to terminal block TB1 located on the center rear of the distribution fuse panel.
Refer to
for location, wire size range, and recommended torque. A pull out wiring guide is available
below terminal block TB1. Note that the top and bottom portions of terminal block TB1 can be separated from
the distribution fuse panel to allow easy wiring.
Major Alarm
If terminals 12 and 13 of TB1 are shorted together (such as a relay closure between these terminals); relay
contacts open between terminals 14 and 15 of TB1 and relay contacts close between terminals 15 and 16 of TB1.
Normal operation provides closed relay contacts between terminals 14 and 15 of TB1 and open relay contacts
between terminals 15 and 16 of TB1.
Minor Alarm
If terminals 1 and 2 of TB1 are shorted together (such as a relay closure between these terminals); relay
contacts open between terminals 3 and 4 of TB1 and relay contacts close between terminals 4 and 5 of TB1.
Normal operation provides closed relay contacts between terminals 3 and 4 of TB1 and open relay contacts
between terminals 4 and 5 of TB1.
A Power Fail Alarm
If no power is detected on the distribution fuse panel Side A input, relay contacts open between terminals 18
and 19 of TB1 and relay contacts close between terminals 17 and 18 of TB1. Normal operation (Side A
energized) provides closed relay contacts between terminals 18 and 19 of TB1 and open relay contacts between
terminals 17 and 18 of TB1.
B Power Fail Alarm
If no power is detected on the distribution fuse panel Side B input, relay contacts open between terminals 21
and 22 of TB1 and relay contacts close between terminals 20 and 21 of TB1. Normal operation (Side B
energized) provides closed relay contacts between terminals 21 and 22 of TB1 and open relay contacts between
terminals 20 and 21 of TB1.
