Section 7: Electrical Installation
Electrical installation consists of the following processes:
• Providing power and ground to a disconnect near the scoreboard.
• Routing power and ground from the main disconnect to the scoreboard driver/power
enclosure.
• Connecting the scoreboard ground to a grounding electrode at the scoreboard
location.
• Routing the control signal cable from the control location to the scoreboard location.
Note: Only qualified individuals should perform power routing and termination to the display.
It is the responsibility of the electrical contractor to ensure that all electrical work meets or
exceeds local and national codes.

Daktronics outdoor LED scoreboards have been designed for easy access to
components, and the power and control signal hookup has been simplified. Front
panels are removable to allow access to the digits, cabling, and other electronic
components.
Correct power installation is imperative for proper display operation. The
subsections that follow give details of display power installation. Only qualified
individuals should attempt to complete the electrical installation; untrained personnel
should not attempt to install these displays or any of the electrical components.
Improper installation could result in serious damage to the equipment and could be
hazardous to personnel.
The multi-section outdoor scoreboards require a dedicated, 120 V circuit for
incoming power. The display itself has no breakers or fuses.
WARNING: It is critical that the scoreboard circuit be fused at 15 A, and that all
conductors used must be designed to pass a 15 A current in normal operation. Failure
to meet wiring an overcurrent protection device requirements is a violation of the
National Electrical Code
® and will void the scoreboard warranty.
All power conductors are 14 AWG, except where 18 AWG wiring is called out on
the schematic. All signal conductors are 18 AWG.
Refer to the outdoor scoreboard schematic listed above and to the chart in Section 5
to determine circuit specifications and maximum power requirements for the models
described in this manual.
