Daktronics Outdoor LED Scoreboards Installation - Manual (Page 15)

Mechanical Installation 9
1. Position the scoreboard at the front of the beams, and lift it to the desired height.
2. Place a C-channel against the upper rear flange of the scoreboard next to each beam.
3. With the C-channel as a template, use a
9 /
16
" bit to drill holes in the upper rear flange
of the scoreboard cabinet where the bolts will pass through. The bolts should be as
close to the beam as possible.
4. Slide a lock washer, flat washer, and I-beam clamp onto each bolt, then push the bolts
through the holes in the rear flange of the scoreboard cabinet and into the C-channel.
5. Place the 2 washer plates and 1 /
2
" square nuts inside the C-channel, and loosely
tighten the square nut onto the bolts.
6. Make final adjustments in the positioning of the scoreboard to ensure it is flush and
level, and then firmly tighten all of the bolts to 40 ft-lb torque.
7. Screw the self-drilling screws into the rear flange, snug up against the I-beam clamps.
8. Repeat steps 2-7 for the lower rear flange of the scoreboard for every beam.
2.4 Ad Panel Mounting
Unistrut Attachment
1. Using the backup channel as a
template, drill four 7 /
16
" holes in
the upper and lower rear flanges
of the ad panel where the beams
will be located.
Note: Try to ensure that the two
center holes will be within the
width of the beam.
2. If the ad panel has backsheets,
remove them as needed to access
the ad panel interior.
3. Attach the piece of unistrut to the
ad panel with the included
hardware, as shown in Figure 10.
4. If any backsheets were removed,
put them back on at this time.
5. Place spring nuts into the unistrut. Twist the spring nuts until they are perpendicular
to the unistrut channel (refer to Figure 4 from Section 2.2).
Once the unistrut is attached and the spring nuts are in place, refer to the appropriate section
below for the type of mounting hardware provided with the ad panel.
