3.1 Conduit
Daktronics does not include the conduit. Separate conduit must be used to route:
• power.
• signal IN wires to the signal termination enclosure, when applicable.
• signal OUT wires (if not using the provided interconnect cable).
Displays are provided with unthreaded power knockouts on the back for use with 3/4”
conduit. The 8-pixel high displays have a J-box on the back for power termination.
3.2 Overview of Power/ Signal Connection
Following is a brief summary of the power and signal connections to the display.
1.
Power to the display will be terminated internally in most cases. Section 3.5 shows
the internal wiring diagrams.
2. Possible methods for signal termination are shown in the manual for the specific
communication type.
3.
Power is routed 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.)
Note: Displays are equipped with overcurrent protection devices that carry a UL489 or
UL1077 (IEC 60947, VDE 660) rating. These devices are only intended to protect the
components within the display. Suitable devices must be used for the equipment and
feeders supplying power to the display.
