Section 4: 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 display location
Routing the control signal cable from the control location to the display 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. All four
tennis scoreboards described in this manual are accessible from the front only.
Internal components are serviced by removing the face panels or digit panels on the
front of the scoreboard. To remove a panel, loosen the screws, slide the panel
upward on the keyhole opening, and lift off. Some panels may be hinged and require
only the removal of screws.
Correct power installation is imperative for proper display operation. The
subsections that follow give details of 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.
Daktronics tennis scoreboards require one dedicated 120 V circuit for incoming
power.
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 and over current 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 22 AWG. For more information on power
requirements, refer to
Drawings B-181793 , B-185759 or B-193461 .
