Daktronics DataMaster displays have been designed for simple hook-up of power
and signal. Correct power installation is imperative for proper display operation.
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. Refer to
Drawing A-263988
and
to the chart in
Section 2
to determine maximum power requirements for this model.
It is critical that the display 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 display warranty.
Grounding

...........................
Drawing A-263988
Displays MUST be grounded according to the provisions outlined in
Article 250 of the National Electrical Code and according to the
specifications in this manual.
The display system
must
be connected to an earth electrode installed at the display.
Proper grounding is necessary for reliable equipment operation. It also protects the
equipment from damaging electrical disturbances and lightning.
The display must
be properly grounded or the warranty will be void.
Refer to
Schematic

A-263988.
Important points about grounding:
•
Follow local and national codes: The material of an earth-ground electrode
differs from region to region and from conditions present at the site.
