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 top 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 a nut onto each threaded rod so that the bracket is loosely held in place.
6. Repeat steps 3 - 5 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 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.
