Power Requirements
Refer to the specifications sheet (SL-3025) for voltage and current requirements. The displays are
sufficiently powered by a 120VAC single -phase outlet.
Do not connect the display to any voltage other than that listed on the Daktronics product label
attached to the back of the display.
Grounding
Proper grounding is necessary for reliable equipment operation and provides some protection to the
equipment from damaging electrical disturbances. The displays are supplied with a power cord that
contains an earth ground conductor. Make sure to plug this cord into a grounded outlet. If the
proper grounding methods are not followed, the warranty will be void.
