Electrical Installation 9
The diagram shown in Figure 11 illustrates a typical wireless setup between a scoreboard and
the control system. Refer to Section 4.5 for more information about the wireless radio option.
3.2 Indoor Scoreboard Power
Indoor scoreboards feature 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. Displays operating on
240 VAC are also available, and they are shipped equipped with a universal power plug. The
control console requires a 120 VAC receptacle and uses less than 1 A of power.
Note: If the power cord is not already installed, refer to Drawing A-1166920.
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.
