3.4 Preparing for Power/Signal Connection
Reference Drawings:
Shop Drawings .........................................................Refer to Appendix A
1. To create an opening for display power and interconnect signal cable in the
back of the display, punch or drill through the knockouts in the lower right
corner from the rear. Refer to the Shop Drawings for appropriate locations.
2. 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.
3. Power conductors from the disconnect to the display should be routed
through conduit in agreement with local code. Run the power and signal
cables in a separate conduit.
4. Display power will terminate to the display at the power termination box
located behind the second module from the left when viewed from the front.
5. Connect the grounding electrode conductor to the display at the ground lug.
6. An enclosure is provided with the display for termination of signal. (If the
installation of the display does not allow for the use of the enclosure, the
manual for the communication type shows the alternate termination method
for the signal.)
7. Signal into the enclosure must be routed through conduit. The size of the
knockouts in the enclosure requires the use of ½” conduit.
8. The quick connect cable from the enclosure to the display can be routed
through conduit or the display pole.
9. Note: Daktronics engineers strongly recommends that the quick connect
cable be secured to protect it from weather of vandalism.
