12.4 Controller Section Operation and Settings. At this point, before the final

installation connections, read sections 13 through 21, covering the Control Panel

operation. Next, go back to sections 19, 20 and 21 and make the signal connec-

tions, 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 has a hazardous voltage at its terminals. Also remember to

allow 5 minutes for internal capacitors to discharge after disconnecting

the AC input power and the battery.

12.5 Connection to Loads. 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.

See Figures 2 and 4. 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 as

shown in Figure 4.

12.6 Connection to Battery. With AC input unplugged, remove the three rectifier

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 DIN-Rail battery termi-

nals shown in Figure 2. while observing the correct polarity.

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).

Set the battery circuit breaker to the ON position and observe the reading on the

digital voltmeter on the controller panel or connected to the test points. It

should indicate the voltage of the battery, approximately 48, 24, and 12VDC

when charged. If the battery is connected with wrong polarity, there will be no

reading on the test points.
