MECHANICAL INSTALLATION
The mechanical installation includes installing the posts and mounting the scoreboard and the optional sponsor panels (if purchased) to the posts.
Post Installation The scoreboard mounts on two posts. Typically installers will use steel pipes or I-beams. In order to reduce the glare from the sun on the front of the scoreboard, position the posts so that the front of the scoreboard is angled away from the afternoon sun, if possible. The mounting hardware will accommodate posts up to 4.5 inches outer diameter. Sink the posts in reinforced concrete footings. Figure 1 shows the spacing of the posts for the 1390 scoreboard. The specifications for the posts and concrete footings are dependent upon the expected local wind and soil conditions, the height of the scoreboard from the ground, and the local building codes. Electro-Mech Scoreboard Company assumes no responsibility for the installation of scoreboards by others.
Figure 2 shows the spacing of the posts for a 1390 scoreboard with an optional side sponsor panel. The sponsor panel is built into the scoreboard cabinet.
Figure 3 shows the spacing of the posts for a 1390 with two optional sponsor panels. These sponsor panels are built into the scoreboard cabinet.
Figure 4 shows the spacing of the posts for a 1390 with an optional top sponsor panel. This panel is a separate unit that mounts on the same posts as the scoreboard.
Mounting The Scoreboard The scoreboard is attached to the posts at four points. Figure 5 shows the location of the mounting points on the rear of the scoreboard.

ELECTRICAL INSTALLATION
We recommend a qualified electrician perform the needed electrical connections to ensure proper operation of the scoreboard. These connections include grounding the scoreboard, connecting the scoreboard to a power source, installing the horn, installing the SL-330 or the control cable, and connecting the control console.
| Ground Connection | ||
|---|---|---|
| The National Electrical Code | requires a scoreboard (electric sign) to be grounded. Grounding the | |
| scoreboard helps the scoreboard electronics operate properly and helps minimize damage if it is struck by | ||
| lightning. Metal posts do | not provide an adequate ground path. The following steps describe how to | |
| connect the scoreboard to the power source: | ||
| 1. | Drive one or more 5/8” x 8’ copper clad ground rods in the soil near the scoreboard. | |
| 2. | Connect #6 bare copper wire to the ground rods using 5/8” brass tear drop connectors. | |
| 3. | Remove the rear access panel and the dome plugs on the plate below the access panel. Figure 7 shows | |
| the location of the access panel and the dome plugs. |

Pass the ground conductor through the right hand hole in the plate below the access panel and connect it to the ground lug (Ground) on the junction chassis.
Power Connections The scoreboard requires 120 VAC service at the scoreboard to operate properly. Maximum power consumption of Model 1390: 144 Watts. Make sure that power cable is rated for this electrical load. Install the power cable in conduit. Avoid running the power cable in close proximity to the control cable. The following steps describe how to connect the scoreboard to the power source:
1. 2. 3.
Feed the power cable through the middle hole in the plate below the access panel. Crimp fork terminals to the power cable wires. Connect the AC line wire and AC neutral wire to the Main Power terminal block on the junction chassis according to Figure 9.
Install a power disconnect that isolates all current carrying conductors on one of the posts below the scoreboard (not the ground conductor). If a secondary switch is installed near the scorekeeper’s table, it should also isolate these conductors. Place the power disconnect in the OFF position between games to help protect the scoreboard from lightning damage. A power disconnect on the scoreboard post also provides a convenient way of turning the scoreboard off during maintenance or repairs.
Horn Installation The items provided to install the horn are the horn, the mounting bolt, and the mounting bracket. Items which are not provided but are necessary for proper installation are ¾” conduit, a two ¾” male conduit connectors, a ¾” straight male conduit connector, two wires, two forked crimp terminals, and two butt splice connectors. The electrical requirements for the horn are 0.35 A 120 VAC. The horn is mounted to the top of the scoreboard. If a horn was purchased with the scoreboard, a tapped hole is provided to fasten the horn to the scoreboard. The mounting bolt is screwed into the tapped hole at the factory. The following steps describe the assembly and mounting of the horn: 1.Cut a piece of ¾” conduit of sufficient length to reach from the horn mounting point to one of holes below the PERIOD panel. 2.Attach the conduit connectors to the ends of the conduit. 3.Cut two pieces of wire of approximately 4 feet longer than the conduit. 4.Push the wires through the conduit. 5.Splice the horn wire leads to the two wires that run through the conduit with the butt splice connectors. 6.Screw the conduit connector into the threaded hole on the weatherproof back box. 7.Fasten the horn assembly to the scoreboard using the mounting bolt from the scoreboard. 8.Crimp forked terminals on the ends of the two wires that protrude out of the other end of the conduit. 9.Pass the wires through one of holes below the PERIOD panel. 10.Fasten the conduit connector to the plate and connect the wires to the Horn terminal block on the junction chassis. Connect the AC-L wire to the left terminal and the AC-N wire to the right terminal.
SL-330 The SL-330 RF MODEM SYSTEM is designed to eliminate the control cable between the scoreboard and the control console on Electro-Mech Scoreboard MM and MP series scoreboards as well as all LED scoreboards. If you have purchased this accessory, disregard the section of this manual titled Control Cable Installation. Refer to the installation manual provided for this product.
Serial Data Output Connections Customers who have purchased a set of delay of game timers can provide one unit with serial data from this scoreboard. This connection is an alternative to providing a delay of game timer with serial data from the control console via the control cable or a SL-330 RF modem. Do not connect the second delay of game timer to this scoreboard. The following steps describe how to transmit serial data from this scoreboard to one delay of game timer: 1.At the rear of the scoreboard, feed data cable (same type of cable specified for control cable on page 3) through a hole in the plate below the access panel. 2.Crimp fork terminals to the cable wires and the shield. 3.Connect the cable to the terminal block labeled Serial Data Output on the junction chassis according to figure 10.

Connect the cable to the terminal block labeled Control Cable on the delay of game timer junction chassis according to figure 11.
8.
Reinstall the delay of game timer rear access panel.
Control Cable Installation The control cable connects the scoreboard to the control console. Install the control cable in conduit. If the cable is ever damaged, it is easier and less expensive to replace a cable in conduit. A small junction box with a ¼” stereo jack mounted on the face plate is attached to the control cable at the point of operation of the scoreboard. This junction box should be securely mounted in a clean, dry area within ten feet of the rear of the control console. Most customers order the control cable with the junction box attached. Some customers prefer to attach the junction box after the cable is installed. Those customers must solder the control cable to the ¼” stereo jack. Figure 12 shows the control cable wire connection points on the rear of the ¼” stereo jack.
1/4" STEREO JACK
The following steps describe how to connect the control cable to the scoreboard: 1.At the rear of the scoreboard feed the control cable one of the holes in the plate to the left of the access panel. 2.Crimp fork terminals to the control cable wires and the shield. 3.Connect the control cable to terminal block labeled Control Cable on the junction chassis according to figure 13.
4.
Reinstall the access panel.
Control Console Connections The 10 ft. extension cable has two molded ¼” stereo plugs attached to it. It is used to connect the control console to the junction box. The following steps describe how to connect the control console:
1. 2. 3.
Plug one end of the extension cable into ¼” stereo jack on the junction box. Plug the other end into the ¼” stereo jack mounted on the control console back plate. Plug the control console power cord into a grounded NEMA 5-15R 120 VAC receptacle.
Control Console Safety Warning
This product is equipped with a 3-wire grounding type plug, a plug having a third (grounding) pin. This plug will only fit into a grounding-type power outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact a qualified electrician to replace your obsolete outlet. Do not defeat the purpose of the grounding-type plug.
SCOREBOARD STARTUP

If the scoreboard turns on LEDs, but does not operate normally, make note of which functions are affected. If some LEDs either never turn on or always stay on, make note of their specific locations on the scoreboard. Refer to the COMPONENT REPLACEMENT section of this manual before changing parts.
COMPONENT REPLACEMENT
LED digits are serviced from the front of the scoreboard.
The LEDs that form digits are soldered on circuit boards mounted behind metal masks. Do not attempt to replace individual LEDs. In case of a malfunction, the entire LED circuit board must be removed. To avoid damage to the LED driver module,always turn off the power to the scoreboard when removing or replacing LED digits. Figure 16 shows the components of a LED digit assembly.
1.
Remove the sheet metal screws that fasten the mask to the face of the scoreboard. Caution: Support the mask before removing the last screw. The ribbon cable that connects to the rear of the circuit board is not designed to support the weight of the assembly. Disconnect the ribbon cable from the rear of the circuit board. Caution: Do not let the cable hang outside of the scoreboard. It is easily cut by sharp metal edges. Damage to the ribbon cable may create short circuit paths that will damage the LED driver module.
