Daktronics MS-2013 Portable LED Scoreboard - Manual (Page 13)

Electrical Operation 7
Section 4: Electrical Operation
The MS-2013 can be powered by two different electrical systems: a standard 120 VAC power source
and/or enclosed lead-acid batteries.
4.1 Power & Signal Access
Power and control connections for the MS-2013 are located in a
compartment on the rear of the scoreboard (Figure 5).
To open the rear compartment, turn the adjustable latch a quarter-
turn to the left. To close, shut the access door and turn the latch to
the right. If the latch will not engage because it is too tight, make
several turns to the left, and then turn back to the right to latch
and tighten.
The compartment is also designed for storage of the control
equipment. The compartment door can be closed with the power
and signal cords extending through the slot below the door.
Note: If the scoreboard came with a 100' (30.5 m) signal cable,
there will be two hooks on the rear of the scoreboard which
the cable may be wrapped around for storage.

Power for the scoreboard is provided in two ways: via standard 120 VAC line, or by means of
two sealed lead-acid DC batteries. Daktronics supplies two 12 V Panasonic
® batteries (Model
LC-X1228P), rated at 28 ampere hours (A/H) as original equipment. Refer to Section 5 for
information on battery care and use of the on-board battery charger.
The provided 8' (2.4 m) 120 VAC power cord plugs directly into the POWER IN 120V AC
receptacle, located in the rear compartment on the back panel of the scoreboard (Figure 5).
Any time 120 VAC power is connected, the internal charger operates; however, the system
will not overcharge the batteries. When the power cord is not connected, the system runs on
battery power.
The MS-2013 is shipped ready for use. The battery charger is factory-mounted in the
scoreboard, and all internal wiring is in place and connected to the driver and batteries.
