Daktronics BA-1518-11 Multi-Section Outdoor LED Scoreboard - Manual (Page 33)

In typical multi-section installations, the lower scoreboard section is installed first and secured to the
support beams, and the upper section is then placed atop or above the lower section and attached to
the beams. There may be cables extending from the top of the lower section. Guide these cables into
the hole in the bottom of the upper section for later connection.
If installers remove the lift eyebolts when the display is permanently mounted, plug the holes with
bolts and the rubber sealing washers that were removed with the eyebolts. Apply silicone or another
waterproof sealant to the eyebolt openings. Inspect the top and sides of the display for any other holes
or openings that may allow moisture to enter the display, and plug and seal those openings as well.

Scoreboards can be mounted to two, three, or four poles. Refer to Section 6.2 to determine the center-
to-center distance of the poles for each model.
Drawing A-44412 shows that the hardware used for mounting the scoreboard to the beams. Each
section of the scoreboard attaches at the top and the bottom to all the beams, Drawing A-44412 also
show top and side views of the scoreboard secured to the beams. Note that the threaded rods do not
pass through the flanges of the beams, but instead run along both sides of each beam.
Review the illustrations of the mounting hardware in Drawing A-44412, and then follow this
procedure for each section:
1. Loosely attach the inner and outer mounting clamps to the rear flanges of the scoreboard's
horizontal frame members, using the 3 /
8
" bolts. Measure the beam spacing and position the
clamps to fit on either side of the beams.
2. Insert a 1 /
2
" square nut into each mounting clamp. Screw a threaded rod into each of the nuts
from the rear.
3. Position the scoreboard at the front of the beams with the threaded rods extending from the
rear of the clamps, straddling the beams. Raise the scoreboard section to the desired height.
4. Slide clamping angles over the ends of the rods and loosely install the washers and nuts.
5. Make final adjustments in the positioning of the scoreboard. Tighten the 3 /
8
" bolts in the
mounting clamps.
6. Make sure that the threaded rods are perpendicular to the scoreboard, and tighten all of the
1 /
2
" nuts.
