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 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 a 1360
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.

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-230 / 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 6 shows the location of the access panel and the dome plugs.

Power Connections
The scoreboard requires 120 VAC service at the scoreboard to operate properly.
Maximum power consumption of Model 1360: 155 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. Feed the power cables through one of the holes in the plate below the access panel.
2. Crimp fork terminals to the power cable wires.
3. Connect the power cable wires to Main Power terminal block on the junction chassis
according to figure 8.
Figure 8 Power Connections
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, 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 in the plate 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.

block on the junction chassis. Connect the AC-L wire to the left terminal and the AC-
N wire to the right terminal.
SL-230 / 330
The SL-230 / 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.
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 9 shows the control
cable wire connection points on the rear of the ¼” stereo jack.
