SPECIFICATIONS
GENERAL: This accessory includes the backboard LED array segment brackets (one TOP bracket, two BOTTOM brackets, and two SIDE brackets), a wire assembly, and a transformer enclosure assembly (If transformer is needed for your application).
DIMENSIONS: TOP BRACKET: 66” L x 1” W x 1” D; SIDE BRACKETS: 30.5” L x 1” W x 1” D; SIDE BRACKETS: 20.25” L x 1” W x 1” D
ARRAY WEIGHT: 3 lbs
CONSTRUCTION: The backboard LED array consists of five segments. Each segment consists of a number of printed circuit board assemblies mounted on a formed aluminum bracket. The brackets are attached to the backboard with very high bond foam tape. The transformer is mounted in a NEMA 4X enclosure (If transformer is needed for your application).
DISPLAY: The backboard LED array illuminates when the basketball scoreboard game clock reaches 0 seconds. It will also illuminate when the scoreboard’s control console HORN key is pressed.
SEGMENTS: Precision optical performance red oval light emitting diodes mounted on printed circuit boards form the segments. Each printed circuit board assembly includes nine high intensity light emitting diodes. The light emitting diodes are spaced 0.6” apart.
POWER REQUIREMENTS:
BACKBOARD LIGHT ASSEMBLY: 18.9 VDC, 7.7A DC each. The backboard LED array is powered by a compatible Electro-Mech Scoreboard shot timer.
TRANSFORMER ENCLOSURE ASSEMBLY: 120 VAC stepped down to 15 VAC, .75A each at 120 VAC, 6.0 A each at 15 VAC, 60 Hz. The backboard LED array is powered by a compatible Electro-Mech basketball scoreboard.
WARRANTY: Five year limited warranty.
OVERVIEW
Backboard lights can be powered by a dedicated output either on any basketball scoreboard or a shot clock with a CPC plug. If they are powered by a basketball scoreboard, a transformer enclosure is required between the scoreboard and the backboard lights assembly. If they are powered by a shot clock with a CPC plug, the shot clock is connected directly to the backboard lights assembly. For both installations the backboard light brackets are installed the same.
BACKBOARD LED ARRAY INSTALLATION INSTRUCTIONS
First determine which configuration you are installing.
If you have a shot clock with a CPC connector on the top (see Fig. 1), then follow the instructions for “Shot Timer Powered Backboard Lights”.
Left: 2180 CPC Location, Right: Close-up of CPC Connector
If you have any other configuration follow the instructions for “Scoreboard Powered Backboard Lights”.
For both types the LED backboard light brackets will be installed the same way as follows.
LED Backboard Light Brackets
1.CLEAN SURFACE OF BACKBOARD BEFORE APPLYING BRACKETS!
2.Remove the white liner from the high bond tape on the backboard light brackets labeled
SIDE and mount them along the left and right side of the backboard glass (inside the white
tape line). Be sure that the LEDs are visible through the backboard glass.
3.Mount the backboard light bracket labeled TOP LEFT in the same manner as in step 1 along
the top left side of the backboard (as viewed from the rear of the backboard).
4.Mount the backboard light bracket labeled TOP RIGHT in the same manner as in step 1
along the top right side of the backboard (as viewed from the rear of the backboard).
5.Mount the backboard light bracket labeled BOTTOM LEFT in the same manner as in step 1
along the bottom left side of the backboard (as viewed from the rear of the backboard).
6.Mount the backboard light bracket labeled BOTTOM RIGHT in the same manner as in step
1 along the bottom right side of the backboard (as viewed from the rear of the backboard).
7.Connect all wire harnesses in the four corners of the backboard as shown in Fig. 2
8.Continue to the next appropriate section for your configuration.

Shot Timer Powered Backboard Lights
1.Plug one side of supplied CPC cable into shot clock.
2.Route cable from shot clock to the four wires on the TOP bracket.
3.Using the wire nuts connect the wires of this cable to the LED backboard lights as shown in
Fig. 2.
4.Installation complete.
Scoreboard Powered Backboard Lights
1.Mount the transformer enclosure assembly within 25 ft. of the backboard. Some mounting hardware has been provided for attachment to a pole.
2.Open the transformer enclosure assembly door (see Fig 3).
