Power Installation 5
Section 3: Power 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 null and void.
Electrical installation consists of the following processes:
• Routing power and ground to the display driver/power enclosure
• Connecting the display ground to a grounding electrode at the display location.
Each Shop Drawing shows details on installation and access for electrical connections. Refer to the
notes on the appropriated 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.
It is the responsibility of the electrical contractor 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.
The dedicated 120 V 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. All local and national electrical codes must be followed 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.
Conductors of circuits delivering power to a Daktronics display shall be sized in accordance
with local and national electrical codes so that the power distribution systems is capable of
delivering full load power to the display while maintaining a voltage within 5 percent of the
utility nominal voltage.
