9) With the main power supply turned OFF, plug
the AC power cord into the AC outlet.
10) Momentarily press each circuit breaker to
verify that it is not tripped.
11) Place the main power supply power switch in
the ON position.
WARNING!
Hazardous voltage that may cause death
or injury is exposed at the power supply
AC terminal.
12) Verify that all main power supply power indi-
cator LEDs are on (RINGER LED should be
pulsating rapidly). If any of the LEDs are
not
on, replace the main power supply.
13) Using a multimeter (set to the appropriate
ranges), check the pins on connectors 5201,
J202,5203 and J703 for the voltages shown
in Figure 4-3. (The connectors are on the rear
of the power supply chassis.) Measure be-
tween the voltage pin and a ground pin, (Ail
ground leads are tied to a single point, so any
can be used.) Figure 4-3 also shows the
acceptable range for each output voltage. If a
measured voltage falls outside of the accept-
able range, replace the main power supply.
14) Turn the power supply OFF and then connect
J201, J202 and J203, respectively, as shown
in Figure 4-2.
15) Remove and retain the two screws securing
the peak load battery mounting bracket and
slide the bracket out the front of the basic
cabinet.
16) Install the peak load battery as shown in
Figure 4-4. Secure the battery to the mounting
bracket with the retaining strap and a single
screw.
WARNING!
Hazardous voltage that may cause death
or injury is exposed at the peak load bat-
tery cables. DO NOT touch wires together.
17) Connect the peak load battery cables to TB2
on the rear of the basic power supply (see
Figure 4-2). Ensure that the correct polarity is
observed as follows:
blue to positive (+)
yellow to negative (-)
