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.

Power specifications for the baseball scoreboard are listed in Section 2 .
Daktronics outdoor LED scoreboards have been designed for easy access to the
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.
Baseball scoreboards BA-2001, BA-2002, BA-2008, BA-2009 and BA-2018 require
a dedicated, 120 V circuit for incoming power. The displays themselves have no
breakers or fuses.
