Daktronics Tuff Sport & ColorSmart Indoor LED Scoreboards - Manual (Page 14)

8 Electrical Installation
The diagram shown in Figure 6 illustrates a typical wireless setup between a scoreboard and
the control system. Refer to Section 5.3 for more information about the wireless radio option.
3.2 Power
Each scoreboard 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 120/240 VAC receptacle and uses less than 1 A of power.
Note: Certain scoring modules require connections to other scoreboards for power and
signal. Refer to Section 3.4 and Section 3.5 for more information.
Displays operating on 240 VAC are also available (excluding ColorSmart models), 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.
