MGE UPS Systems S3 - Manual (Page 21)

Three alarm relays are provided. 1) UTILITY FAILURE, 2)
MINOR alarm, 3) MAJOR alarm.
All relays are identical,
however the UTILITY and MINOR relays are wired as a
SPDT units, whereas the MAJOR alarm relay is a DPDT unit.
Relays are energized under normal operating condition. De-
energizing of the relays results in an ALARM signal as shown
in figure 1-2. Relay contact rating is 2 amperes maximum for
120/240VAC, 25 to 125VDC with a switched load of 50 Watts.
Connection diagram is clearly labeled on the rear panel for
these alarm relays. See Figure 1-2.
