Wire connector P2 (refer to Fig. 6) according to Table G.
♦
Wire discrete alarm inputs 25-32 (all options). There are two
wires for each input (+ and -). Refer to Fig. 8 for typical wir-
ing circuits.
♦
Wire the control relay outputs 1-16 (1-8 for all options, 9-16
for options -01 and -21).
♦
Wire the change-of-status (COS) relay, COS acknowledge,
and fuse alarm (all options).
WARNING:
When power is applied to the APU, negative battery voltage is
present at pins 54 and 56 of connector P2 and at any alarm
inputs wired to negative battery. For safety, cover these pins
with protective insulation.
