Basic Component Removal Procedures

The procedures in this section are required by many of the replacement
procedures described in this manual in addition to replacement of these
components themselves.

DO NOT perform any of the procedures in this section unless specified by the
instructions for the component you are replacing.

Remove Main Control Panel
Assembly

Refer to the figures in

Component Diagrams and Torque Specs on page 13

for

these instructions.

Remove Components

1.

Read and follow the

Safety Precautions on page 9

Important Initial

Steps on page 11

.

2.

Remove safety shields as needed.

3.

Remove the ribbon cable going from the Main Control Board ( J2) to
the Power Interface Board ( J1).

4.

Remove the two screws on the Main Control Panel below TB11 for the
Main Control Board.

5.

Verify that all wiring to lower side of TB11 is properly labeled and then
disconnect wiring from TB11.
