3 Electrical Installation
Electrical installation consists of routing power to the power supply located in each
display face.
Each
Shop Drawing
shows details on installation and access for electrical connections.
Refer to the notes on the appropriate
Shop Drawing
for the electrical requirements for
that size of display.
The front panels of Daktronics Fuelight
™
displays are hinged to allow access to the
digits, cabling, and other electronic components. Refer to
for cabinet access details.
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.
Important Notes:
•
Only qualified individuals should perform power and signal routing to the display and
termination at the display.
• Daktronics engineering staff must approve all proposed changes, or the warranty will
be void.
• Improper installation could result in serious damage to the equipment and could be
hazardous to personnel.
• Size conductors of circuits delivering power to a Daktronics display according to local
and national electrical codes so that the power distribution systems can deliver full-
load power to the display while maintaining a voltage within 5% of the utility nominal
voltage.
Power Requirements
Do not connect displays to any voltage other than that listed on the display product
label. Fuelight
™
displays have a voltage input of 100-240 VAC and a frequency input of
50/60 Hz.
• The dedicated circuit can be shared among all components of the sign structure
(including Fuelight
™
displays and fluorescent lighting), but not with other external
electrical devices (such as air compressors or island lighting).
•
A dedicated circuit is defined as one hot, one neutral, and one ground wire.
• Maximum amperage varies with the number and type of digit displays connected.
Note:
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 may violate
local and national electrical codes and will void the display warranty.
