Section 3: Power Installation
Read the Mechanical, Power, and Signal Installation sections
before installing the display(s).
Only a qualified individual should terminate power and signal cable at this
Daktronics display.
All proposed changes must be approved by Daktronics engineering staff or
the warranty will be rendered null and void.
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)
The power J-box is provided with 3/4” threaded holes for use with 3/4” conduit.
Unthreaded 1/2" knockout holes are provided in the signal enclosures used with the
display. If not using the provided enclosures, use the knockout/ drill holes provided
in the display cabinet.
3.2 Overview of Power/ Signal Connection
Following is a brief summary of the power and signal connections to the display.
1. Enclosures are provided with the display for termination of both signal and

enclosures, refer to Section 3.5 for diagrams on internal wiring for the
power.
2. Possible methods for signal termination are shown in the manual for the
specific communication type.
3. Route power to the display through a fused disconnect switch capable of

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 for 1 and 2 circuit power termination panels: Displays are equipped with
supplemental protection devices that carry a 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.
4. Power conductors from the disconnect to the display should be routed
through conduit in agreement with local code.
