Section 4: 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.
4.1 Installation Overview
Refer to Drawing A-124689 in Appendix A for power and signal layouts for typical hockey
scoring systems.
Note: Control signal cable and some junction boxes are not provided as part of this
system and can be purchased locally or from Daktronics.
4.2 Power
Each scoreboard (except H-2103) 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.
The control console requires a 120 VAC receptacle and uses less than 1 A of power.
Note: The H-2103 scoreboard module receives power and signal from a nearby module,
such as the H-2102 or H-2115. Refer to Section
‎
4.4 for more information.
Displays operating on 230 VAC are also available, and they are shipped equipped with a
universal power plug.
Grounding
Connect the scoreboard 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 scoreboard.
Note: The customer must properly ground the outlet according to local and national
codes. Failure to ground the outlet voids the warranty for the scoreboard.
4.3 Power-On Self-Test (POST)
The scoreboard performs a self-test each time that power is turned on and the control console
is powered off or not attached to the scoreboard. If the control console is attached and
powered on, the self-test does not run, and data from the control console is displayed on the
scoreboard after a brief period of time. Each scoreboard self-test pattern will vary depending
on the scoreboard model, the number of drivers, and types of digits.
