5 Electrical Installation
This section explains the steps necessary to make final electrical connections to the
display from the primary power source. For display-specific power requirements, refer to
the shop drawing or label on the display's back.
Electrical Installation Preparation
• Do follow all installation guidelines
• Do route power to the display through a disconnect switch
• Do provide the required power per display requirements
• Do provide a separate circuit for each display
Note: Run a separate circuit to the electronic display(s) to isolate it and prevent
any issues that could be caused by line voltage fluctuations or high
frequency noise on the power line caused by other types of equipment.
A separate circuit also makes display maintenance and troubleshooting
easier. Daktronics assumes no liability for any issues caused by line voltage
fluctuations or other improper power conditions.
• Do connect each display face to a dedicated earth-ground electrode
• Do follow all local and national electrical codes
• Do not share circuits between displays and other electrical devices
• Do not connect the display to any voltage other than that listed on the product label
• Do not connect the neutral to the ground at the disconnect or the display
• Do not use the display support structure as an earth-ground per local and national
codes
Conduit
Daktronics does not provide 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).
For power, displays have a 1

/
4
″ Myers hub located near the lower right on the back of
the display. For signal, displays have signal input quick connects or etched drilling guides
for conduit.
Power Requirements
Install this display according to all applicable local and national electrical codes. This
includes proper grounding and bonding of the display.
Do not connect the display to any voltage other than that listed on the Daktronics
product label.
Displays use single-phase power. Proper power installation is imperative for display
operation. Find power specifications on drawings shipped with the display.
