Qualified personnel should perform the scoreboard installation. Consult national and local codes before installation.

MECHANICAL INSTALLATION

The mechanical installation includes installing the posts and mounting the scoreboard and the optional top sponsor panel (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 a MP-363. 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 MP-9350 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 MP-9350 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 4 shows the location of the mounting points on the rear of the scoreboard.

Four sets of mounting hardware are provided to attach the scoreboard to the posts. A mounting hardware set consists of a steel angle bracket, two threaded rods, two washers, and two nuts. Figure 5 shows an overhead cross section view and a side cross section view of the scoreboard attached to a post at a mounting point using the hardware. A ¼” flat bar with tapped holes is riveted to the inside of the scoreboard’s aluminum extrusion frame. The threaded rods screw into these tapped holes. The washers and nuts are used to clamp the steel angle bracket against the steel post and hold the scoreboard in place.

The following steps describe how to mount the scoreboard on the posts:

1.Place the scoreboard cabinet against the posts on the ground. Make sure the mounting points are aligned with the posts. 2.Screw the threaded rods into the tapped holes in the scoreboard. 3.Place a steel angle bracket over the threaded rods at a mounting point. 4.Place a washer over each threaded rod. 5.Screw the nuts onto the threaded rods so that the bracket is loosely held in place. 6.Repeat steps 4 -6 at the other mounting points. 7.Raise the scoreboard into place and tighten the nuts to clamp the scoreboard in place on the posts.

Note: Be sure to leave enough space on the posts above the scoreboard for the optional top sponsor panel, if purchased.

Mounting The Optional Top Sponsor Panel Additional hardware sets are provided to attach the optional top sponsor panels, if purchased. The following steps describe how to mount the top sponsor panel on the posts:

1.Raise the sponsor panel in place above the scoreboard. Make sure the mounting points are aligned with the posts. 2.Screw the threaded rods into the tapped holes in the top sponsor panel. 3.Place a steel angle bracket over the threaded rods at a mounting point. 4.Place a washer over each threaded rod. 5.Screw the nuts onto the threaded rods so that the bracket is loosely held in place. 6.Repeat steps 4 -6 at the other mounting points. 7.Tighten the nuts to clamp it in place on the posts.

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 ScoreLink 300 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.Attach the ground conductor to the each section of the scoreboard with copper mechanical lugs. Fasten the mechanical lugs to the scoreboard using self tapping sheet metal screws.

Power Connections The scoreboard may be connected to 240 VAC single phase or 120 VAC service at the scoreboard. Maximum power consumption of Model MP-9350: 2730 Watts. Make sure that the power cables are 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.Remove the rear access panel and the dome plugs on the plate below the access panel. Figure 6 shows the location of the rear access panel and the dome plugs.

2.Figure 7 shows the view behind the access panel. Feed the power cables through one of the holes in the plate below the access panel. 3.Crimp fork terminals to the power cable wires.

4.If you are going to connect the scoreboard to a 240 VAC supply, connect one AC line wire to position 2, AC neutral wire to position 3, and the other AC line wire to position 4 of terminal strip T4 on the junction chassis according to figure 8.

5.If you are going to connect the scoreboard to a 120 VAC supply, connect the AC line wire to position 2 and the AC neutral wire to position 3 of terminal strip T4 on the junction chassis. Add a jumper from position 2 to position 4. This jumper is not provided. Refer 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” flexible 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. 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 the knockouts below the access 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.Peel the tape off the horn projector. 6.Remove the plastic bag from inside the horn projector. 7.Remove the four screws that fasten the horn and horn projector to the weatherproof back box. 8.Feed the two wire leads that are attached to the rear side of the horn through one of the threaded holes on the side of the weatherproof back box. Two of the holes will accept a ¾” conduit connector. 9.Plug the other two threaded holes with the plugs from the plastic bag. 10.Splice the horn wire leads to the two wires that run through the conduit with the butt splice connectors. 11.Screw the conduit connector into the threaded hole on the weatherproof back box. 12.Attach the horn and horn projector to the weatherproof back box using the four screws. 13.Fasten the horn assembly to the scoreboard using the mounting bolt from the scoreboard. 14.Crimp forked terminals on the ends of the two wires that protrude out of the other end of the conduit. 15.Pass the wires through one of the knockouts below the access panel. 16.Fasten the conduit connector to the knockout panel and connect the wires to T-2 behind the access panel.

ScoreLink 300 The ScoreLink 300 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 ScoreLink 300 RF MODEM SYSTEM OWNER’S HANDBOOK for installation instructions.

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 10 shows the control cable wire connection points on the rear of the ¼” 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 below the access panel. 2.Crimp fork terminals to the control cable wires and the shield. 3.Connect the control cable to T1 terminal block on the junction chassis according to figure 11.

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.Plug one end of the extension cable into ¼” stereo jack on the junction box or the ScoreLink 300 Transmitter, if purchased. 2.Plug the other end into the ¼” stereo jack mounted on the control console back plate. 3.Plug the control console power cord into a grounded NEMA 5-15R 120 VAC receptacle.

Control Console Safety Warning
