1. Install a grounded receptacle near the display so that it is accessible to plug in the power
cord. Each scoreboard is equipped with a 120V AC, three-prong plug for power in and
power out.
2. Determine which section is the closest to the grounded 120V AC receptacle. Connect the
power cord that is on the right side (when viewed from the rear) of the section and plug it
into the left side of the next section.
3. Continue to connect each section to the next until all the sections are connected.
4. Connect the remaining power cord to the grounded 120V AC receptacle.
2.4 Grounding
The circuit outlets must contain connections to earth-ground. Proper grounding assures reliable and
safe equipment operation. Proper grounding will also protect the equipment from damaging electrical
disturbances and lightning. The grounding connection on the three-prong plug power cord connects
to the shell of the scoreboard.
