FEBRUARY 1992
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 J201,
J202, J203, J703 and J803 for the voltages
shown in Figure 4-9. (The connectors are on
the rear of the power supply chassis.) Meas-
ure between the voltage pin and a ground pin.
(All ground leads are tied to a single point, so
any can be used.) Figure 4-9 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 4-9.
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 4-4). Ensure that the correct polarity is
observed as follows:
blue to positive (+)
yellow to negative (-)
18) Slide the mounting bracket/battery assembly
in place and secure with two screws.
19) Set the BATTERY BACKUP switch to
OFF
