Routing power and ground from the main disconnect to the power connection
pigtail in the display.
Connecting the display ground to a grounding electrode at the sign location.
Routing the control signal cable from the control location to the sign location.

Daktronics DataMaster displays have been designed for easy access to components,
and the power and control signal hookup has been simplified. Front panels are
removable or hinged 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 DataMaster outdoor displays require a dedicated, 120 V circuit for incoming
power. The display itself has no breakers or fuses.
