• For a GMT fuse, pull out dummy fuse, and insert
operable fuse, as shown in Figure 11.
30. Check the voltage and polarity at the input of each
equipment load.
31. If possible,
• Temporarily replace one of the operable TPA fuses
with a blown fuse to check that the
FUSE ALARM
and the TPA Fuse LEDs light red. Also, check the
FUSE ALARM
terminals on the rear of the panel:
− Expect an open circuit (00Ω) between Terminals
C
and
NC
.
− Expect continuity (0Ω) between Terminals
C
and
NO
. Re-install the operable TPA fuse before pro-
ceeding.
• Likewise, replace one of the operable GMT fuses
with a blown fuse to verify that the
FUSE ALARM
LED and
FUSE ALARM
terminals are also as
specifi ed above. Re-install an operable GMT fuse
before proceeding.
32. If desired, connect remote external audio/visual
alarm indicator wires (solid or tinned wires, #22 to
#12 AWG) to the
PWR FAIL
and
FUSE ALARM
terminals, as shown in Figure 12.
33. Carefully re-install the rear cover.
34. Record the TPA and GMT output destinations on
designation labels on the front panel.
35. Turn on equipment loads one at a time to verify
proper operation of loads.
