17.
Output connections:
Connect the devices to be powered to the removable terminals marked [– OUT1 +] to [– OUT8 +] for
Maximal1RH and Maximal3RH. For Maximal1R, Maximal3R, and Maximal33R connect devices to the
second set of terminals marked [– OUT1 +] to [– OUT8 +]
(Fig. 15c, pg. 12)
.

Fire Alarm Interface connection options:
a. Connect the FACP trigger input to the removable terminals marked FACP1 and FACP2. When using the
polarity reversal from an FACP signaling circuit, connect the negative [–] to the terminal marked FACP1
and the positive [+] to the terminal marked FACP2 (polarity is in alarm condition)
(Rack Mechanical Drawing and Dimensions pg. 12)
.
b. For a latching fire alarm interface connect a normally [NO] reset switch to the removable terminals
marked [REST] and [GND]
(Figs. 6-11, pg. 9)
.
19. Set the power disconnect circuit breaker to the ON position
(Fig. 15a, pg. 12)
.
Maintenance:
Unit should be tested at least once a year for the proper operation as follows:
Output Voltage Test:
Under normal load conditions the DC output voltage should be checked for proper voltage
level
(Output Voltage and Stand-by Specification Charts, pg. 5).
Battery Test:
Under normal load conditions check that the battery is fully charged, check specified voltage at
the battery terminals and at the board terminals marked [– BAT +] to ensure that there is no break in the battery
connection wires.
