X75 SERIES
INSTALLATION & OPERATING MANUAL
Manual No. x75-10b
x75-man-Rev10b-0514.indd
One by one, turn each output circuit breaker to the ON position and/or insert a GMT
fuse and measure the DC voltage across the corresponding output terminals. The
voltage should again read approximately 54.4, 27.2, or 13.6 volts. After each output
is measured, turn OFF that circuit breaker and/or remove the GMT fuse and turn
ON and/or insert a fuse in the next one. After measuring the last circuit, turn off that
breaker and/or remove the GMT fuse and make sure that all output breakers are in
the OFF position and/or all fuses are removed.
Unplug or disconnect the AC input power source. Before touching any terminals
wait 5 minutes for the internal storage capacitors to discharge.
12.3 ControllerSectionOperationandSettings
At this point, before the nal installation connections, read section 13 covering
Controller setup. Next, make any required signal connections, controller adjustments,
temperature compensation adjustment and alarm enabling settings.
WARNING: Remember to take precautions each time the system is turned on and also
when connecting or disconnecting the battery. Remember that the battery presents
an energy hazard at its terminals. Also remember to allow 5 minutes for internal
capacitors to discharge after disconnecting the AC input power and the battery.
12.4 ConnectiontoLoads
With input AC power unplugged, the battery disconnected and no other power sources
connected to the loads, make sure that all load circuit breakers are set to the OFF
position and/or all GMT fuses are removed.
Connect load wires to each set of output terminals, one at a time. Note that the front
panel breaker and fuse numbers directly correspond to the output terminal numbers.
Be sure to connect the polarities correctly.
12.5 ConnectiontoBattery
WARNING: Improper polarity of the battery connection may damage the power
system. Take precautions when installing the battery and note that the battery cables
are “hot” (live) and present an energy hazard.
With AC input unplugged, remove the three rectier modules from the system chassis.
Make sure all load circuit breakers are in the OFF position and/or all GMT fuses
removed. Set the battery circuit breaker to the OFF position. Carefully connect the
battery cables to the battery terminals shown in Figure 4 while observing the correct
polarity as described in section 9.4.
