3.5 Preparing for Power/Signal Connection
Reference Drawings:
Component
Layout Drawings................................... Refer to Appendix A
1. Remove the two bottom left modules (AX01 and AX02) to expose the
power enclosure and controller. Use a
1
/
8
" Allen 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.

2. Locate the controller and
power termination box for
these displays in the
Component Layout
Diagram located within
Appendix A.
3. Punch or use 7/8" (0.875)
holes for the desired ½"
conduits. Be careful that
none of the internal
components are damaged.
Attach the conduit.
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.
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 also. Unless you are using fiber, be sure to run the power and
signal cables in a separate conduit.

Power Requirements
Refer to Drawing A-180190 for voltage and current requirements for your display
size and pixel color. Each uses a 120VAC or 120/240 VAC single-phase power
source. Depending on the module color and display size, the power supply may vary.
Do not connect the displays to any voltage other than that listed on the
Daktronics product label.
