Section 3:

Electrical Installation

CAUTION: Only qualified individuals should access the electrical components of the display and its
associated equipment. It is the responsibility of the electrical contractor to ensure that all electrical
work meets or exceeds local and national codes.

Daktronics engineering staff must approve all changes or the warranty will be void.

3.1 Installation Overview

Electrical installation involves routing power and control signal wiring through separate
conduit or wire ways. Refer to Drawings A-244179 and A-276200 in Appendix A for
power/signal connections and typical system layouts.

Note: Control signal cable and some junction boxes are not provided as part of this
system and can be purchased locally or from Daktronics.

3.2 Power

Each goal light unit features a 120 VAC power cord with a three-prong plug. Install a
grounded receptacle near the equipment so that the power cord can easily reach it.

Goal lights operating on 230 VAC are also available, and they are shipped equipped with a
universal power plug (Pro & Varsity Models only).

Grounding

Connect the display to earth ground. Proper grounding assures reliable equipment operation
and protects the equipment against damaging electrical disturbances and lightning.
Daktronics recommends a resistance-to-ground of 10 ohms or less. The electrical contractor
performing the electrical installation can verify ground resistance. Daktronics Sales and
Service personnel can also provide this service. The grounding connection on the power
cord‟s three-prong plug connects to the shell of the goal light.

Note: The customer must properly ground the outlet according to local and national codes.
Failure to ground the outlet voids the warranty for the display.
