Daktronics BA-1518-11 Multi-Section Outdoor LED Scoreboard - Manual (Page 35)

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 power and signal
entrance 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.
K 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.

Components 2/4 Pos Power and Signal Entrance ............................... Drawing A-125977
Refer to the chart in Section 3 to determine circuit specifications and maximum power requirements
for the models described in this manual.
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 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 outdoor scoreboards and timing displays require a dedicated, 120 V circuit for incoming
power. The display itself has no breakers or fuses.
K 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
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 22 AWG.
Refer to the outdoor scoreboard schematic listed above and to the chart in Section 1 to determine
circuit specifications and maximum power requirements for the models described in this manual.
