Reference Drawings:
Component Layout Drawings ...................................Refer to Appendix A
1. Punch or use 1/2" (0.875" in diameter)
conduit holes for the desired conduit
openings. Be careful that none of the
internal components are damaged. Attach
the conduit
Electrical Installation 3-6

wrench to turn the latch access fasteners one-
quarter turn. Turn the top latch clockwise and
the bottom latch counter-clockwise. Lift each
module away from the display; reach behind
it and disconnect all power and signal
connections. Refer to Figure 17
3. Locate the controller and power termination
box for these displays in the Component
Layout Diagram for your sign
4. The controller receives the incoming signal
and relays it to the individual modules
5. Route power to the display through a fused
disconnect switch capable of opening all ungrounded power conductors.
Install this disconnect within the line of sight of any personnel performing
maintenance on the display. If the disconnect is located out of sight of the
display, it must be capable of being locked in the open position
Figure 17: Removing a Module
6. Power conductors from the disconnect to the display should be routed
through conduit in agreement with local code
7. You may route the signal cable from the control computer to the display at
this time – Be sure to run the power and signal cables in separate
conduit
