Power Supply
The power supply is mounted on the back of every other
module. The first power supply is located behind module
A*02 (* is the number of the line. Refer to Section 4.2).
This unit supplies power to modules A*01 and A*02. The
remaining power supplies are located behind A*03, A*05,
A*07 and A*09. The power supplies connect to the module
they are located behind and the one to the right of it (as seen
from the front view). This pattern is consistent for each line.
Refer to Section 4.3 for information on removing a module.
Once the module has been removed from the display:
1.
Remove the ground wire from the ground nut.
2.
Unplug the two power wires.
3.
Place the module face down on a soft, flat
surface.
4.
Remove the power module by removing the single
screw on the bottom L-bracket.
5. Pull and slide out the power module.
Follow the above steps in reverse order to install a new power supply.
