6.8.1  REPLACING THE PSU

1.  Remove the rear cover. (See section 6.1.3.)

2.  Lift the PSU [B] out of the machine (5 screws, 4 connectors, 1 grounding wire

[A]).

ø

CAUTION

When removing the PSU, make sure to first turn off the main power and
unplug the power cord. This is done to eliminate the risk of electrical
shock.
