Warnings and Disclaimers
• Ensure that all electrical work meets or exceeds all local or national electrical codes.
• Provide the required power to the display as listed on the product labels,
specifications, or site-specific riser drawings. The conductor size may vary based on
the length of the power run.
• Consider implementing a separate circuit for the display using an isolation
transformer or dedicated transformer.
• Daktronics assumes no liability for any issues caused by line voltage fluctuations or
other improper power conditions.
Installation Overview
Electrical installation involves routing power and control signal wiring through separate
conduit or wire ways.
Note: Control signal cable and some junction boxes are not provided as part of this
system and can be purchased locally or from Daktronics.
Power
Only qualified individuals should complete the electrical installation; untrained personnel
should not attempt to install these displays or any of the electrical components� Improper
installation can seriously damage the equipment and be hazardous to personnel�
Install a grounded receptacle near the equipment so that the power cord can easily
reach it.
Each shot clock control enclosure comes with a 120 or 240 VAC twist lock power plug
that must be attached to a 120 or 240 VAC power cord (by the customer) as follows:
•
120 VAC wiring: Connect black wire to copper terminal, white wire to nickel terminal,
and green wire to green terminal.
• 240 VAC wiring: Connect black wire to copper terminal, red wire to copper terminal,
and green wire to green terminal.
Grounding
All components of a display system – including but not limited to displays, control
equipment, and connected peripheral equipment – must be electrically grounded.
Only qualified individuals may perform electrical work, including verification of ground
resistance. Daktronics is not responsible for improper grounding or damage incurred as a
result of improper grounding.
Grounding methods must meet the provisions of all applicable local and national codes.
Inspect and verify all grounding methods meet the provisions of all applicable local and
national codes.
Proper grounding is necessary for reliable equipment operation and general electrical
safety. Failure to properly ground the display system may void the warranty, disrupt
operation, damage equipment, and cause bodily harm or death.
