19.1 Power Input Section
When servicing the power input section parts, make
sure the built-in circuit breaker and the main power
supply on the power distribution board are both set to
the OFF position. If the main power is left ON,
electricity will flow as far as the power supply section,
and this can cause electric shocks and/or short-
circuiting.
Removal
1. Remove the processor rear cover
.
2. Remove the two screws and then the power input
section cover.
3. Remove the four screws and then the built-in
circuit breaker.
4. Remove the eight screws to disconnect the wires
from the breaker.
Installation
Installation is essentially in the reverse order of
removal.
