Procedure to Install a New Unit
1. Insert and position the new display board in place (Figure 5-4).
2. Replace the six display board nuts, tighten until they are snug (if replacing
unit A, re-install the ribbon-cable clamps).
3. Plug in the ribbon cable, then the terminal block to the display board.
4. Insert and position the new power supply board (Figure 5-3).
5. Replace the six screws that secure the power supply board to the chassis.
6. Plug the ribbon cables back into the power supply board.
7. Replace the unit's metal cover. To avoid future confusion, make sure the
proper cover is on the proper unit. This is important because each cover is
labeled with the unit I.D. letter as well as the correct voltage to be applied to
that unit.
8. Snugly secure the four cover nuts.
9. If you've replaced Unit A, replace the ribbon-cable clamp onto the cover
(Figure 5-2).
10. Plug in the unit's terminal blocks.
