Reassembly - QSC PowerLight Series Technical & Service Manual

circuit board is burned into the fiber layers or badly damaged,
replace the entire module.
See instructions for servicing the power supply module
elsewhere in this chapter.

Reassembly

Reassembling the amplifier chassis is essentially reversing the
order of the disassembly process.
Installing the power supply module
1. Align the keyed slots in the power supply module circuit board
with the chassis standoffs. Watch out for the fish paper
insulators, which may get caught underneath. Drop the
module into place on the standoffs and slide it forward.
2. Using the 11/32" nutdriver or socket wrench, attach the AC
wires to the module. The black wire attaches in front (closer
to the front of the amplifier chassis) of the white one.
3. Using the 5/64" hex (Allen) key, insert and tighten the screw
at the rear of the power supply module.
