3.1 Preparing for Power/Signal Connections
Reference Drawings:
Shop Drawings......................................................... Refer to Appendix A
MF-1000 Series Display Installation ............................ Drawing A-222256
Electrical installation consists of the following processes:
• Providing power and ground to a disconnect near the display.
• Routing power and ground from the main disconnect to the display
enclosure.
• Connecting the ground to a grounding electrode at the display location.
Drawing A-222256 for displays in this series shows the locations of internal
components and electrical access holes. Refer to these drawings before making
power connections. Power terminates to the control board in the display enclosure.
Termination is to be completed by the customer's electrician.
3.2 Power and Grounding Connections
Correct power and grounding installation is imperative for proper display operation.
The subsections that follow give details of display power and installation. Only
qualified individuals should attempt to complete the electrical installation. Improper
installation could result in serious damage to the equipment and could be hazardous
to personnel.
Power
Daktronics status/lane indicator displays have been designed for easy access to
components and to power.
Daktronics MF Series Status/Lane Indicator displays require a dedicated 120 VAC
circuit for incoming power. The display itself has no breakers or fuses.
Power conductors and conduit are to be sized and installed by the customer's
electrician. Knockout-type access holes for the conduit are
7 /
8
" and located on the
back plate.
The table below shows the circuit specifications and maximum power requirements
for each model in this series. Models are listed in order by size and display type.
