Daktronics AF-3400-64-R,A - Manual (Page 21)

Electrical Installation 3-3
3.2 Signal Termination Enclosures
In each communication method, the final connection will be from a provided weather
resistant enclosure to the display. For signal termination to the enclosure, see the
manual included in the box with the enclosure.
Note the following information when mounting the enclosure:
1. Be sure to mount the enclosure with the cables exiting from the bottom to
prevent water from entering into the enclosure.
2. Mount the enclosure securely and if possible at a height or location
inaccessible to vandalism.
3. A quick connect cable will be connected to the signal termination enclosure
and will terminate to the back of the primary display – the length of the
cable is 25 feet.
4. The quick connect cable can be run from the enclosure through 2” conduit
or through the display pole to the display but is not required. The cable is
weather and sunlight resistant.
Note: Daktronics engineers strongly recommend that the quick connect cable be
secured to protect it from weather or vandalism.
5. Earth ground the enclosures that use wire signal cable – the resistance to
ground should be 10 ohms or less (a grounding electrode conductor is
attached to the enclosure to make the necessary earth ground connection)
3.3 Conduit
Reference Drawings:
Shop Drawings......................................................... Refer to Appendix A
Daktronics does not include the conduit. Refer to the Shop Drawing for approximate
locations of power and signal conduit. You must use separate conduit to route:
• Power
• Signal IN wires
• Signal OUT wires (if another display is being utilized)
Locate the conduit holes at the bottom right (rear view) of the back of the display.
Punch or drill out the desired conduit openings. Be careful not to damage any
internal components. Attach the conduit, and then route the power and signal cables.
For displays with more than one face, signal and temperature connection between
displays is done with interconnect signal wiring. The signal output on the first
display will connect to the input on the second. The interconnect wiring is included
in the manual for the communication type. The interconnect wiring for the
temperature sensor is shown in Appendix B.
