Section 3: Electrical Installation
Important Notes:
• Only a qualified individual should terminate power and signal cable at the display.
• All proposed changes must be approved by Daktronics’ engineering staff, or the warranty will be void.
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.
Daktronics Fuelight ™ displays’ front panels are hinged to allow access to the digits, cabling, and other electronic
components. See Section 3.2 for cabinet access details.
Note: Only qualified individuals should perform power routing and termination to the display. It is the electrical
contractor’s responsibility to ensure that all electrical work meets or exceeds local and national codes. Improper
installation could result in serious damage to the equipment and could be hazardous to personnel.
3.1 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 will vary with the number and type of digit displays connected.
• Follow all local and national electrical codes during electrical installation.
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.
• 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 percent of the utility nominal voltage.
Main Disconnect
Daktronics requires using a power disconnect switch with the display. Use a disconnect so that all
ungrounded conductors can be disconnected near the point of power connection.
Locate the disconnecting means either in a direct line of sight from the display or so it can be locked in the
open position. This ensures that power is not reconnected while service personnel work on the display.
