Electrical Installation

Note: Take care during the installation process to ensure the drain holes in the
bottom or the bottom angles of the scoreboard/display are not covered by the
mounting structure.
If they are covered ,
3
/

" holes must be drilled through the
mounting structure in the same spot as the original holes.
Refer to
Drawings A-55101 , B-157568, B-189028, B-202354 and B-221501 for
mounting information. Drawing B-189028 contains detailed footing and beam
information for models TN-2010 and TN-2011. Drawing B-202354 contains
detailed footing and beam information for model TN-2018, Drawing B-221501 for
model TN-2029 and Drawing B-157568 for model TN-2032. Each section of the
scoreboard attaches at the top and the bottom to all the beams. The drawings 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.
Follow this procedure for each section of the scoreboard:
1. Use the mounting channel to determine which hole combination should be
used. Be sure to keep the bolts as close to the beam as possible.
2.
Using the mounting channel as a template, drill
9

16
” holes in the upper and
lower rear flange of the scoreboard.
3. Place

" square nuts inside the channel and thread the bolts through. Refer
to Figure 4 and to Drawings A-55101 , B-157568, B-189028, B-202354
and B-221501 .
4. Slide clamping angles over the ends of the rods and loosely install the split
lock washers and
1

" hex nuts.
5. Make final adjustments in the positioning of the scoreboard. Tighten the
bolts in the mounting clamps.
