Section 3: Display Installation
This section provides general guidelines for DB-4200 display installation. Work closely with the Project
Manager on all installations. Do not modify the display or control system in any manner without the
written permission of the Project Manager as any unauthorized modifications may null and void the
display warranty.
3.1 Display Installation
1. Using a utility knife, carefully cut away all of the white packaging material from the display
and the spare parts box. Pay special attention when cutting around the Multi-Direction Light
Sensor (MDLS) to avoid cutting cables. If possible, do not cut anywhere along the display
face as it can damage the LEDs and modules.
2. Remove the wood and the wood braces from the top of every display section.
3. Lift the spare parts box off of the trailer and set in a location near the installation site as it
contains tools, parts, and documents used for the installation process.
4. Open the spare parts box and verify all installation tools and installation hardware were sent
with the display. Contact the Project Manager immediately if missing installation parts.
5. Verify that the lift-eyes are installed and the lift-eye bolts and set bolts are in place. Refer
to Figure3. The lift eye spacing is set at Daktronics and should not be moved without the
Project Manager's permission.
Angle must be
greater than 55°

6. Attach lift lines from the crane to the lift eyes.
Note:Ensure the angle between the top of the display and the lifting strap is greater than 55°.
Refer to Figure3. The table below shows Daktronics recommended strap lengths for some
common display sizes.
Display Dimensions Minimum Strap Length (L)
14'x48' 25'
10'6"x36' 20'
14'x28' 20'
11'x22' 15'
7. Lift the display to apply some tension to the lift lines.
8. Tie tag lines to the provided tag line tie off on the bottom corners of the display. Refer to
Figure3.
9. Unbolt the display from the trailer by removing the shipping braces.
Note: For displays that require a section splice, complete the steps in Section4 before
continuing the installation process.
10. Locate the center-line label on the back of the display.
11. From the center of the display, measure and align the offset extrusion so it matches the
structure upright spacing. If a section splice is required, measure the spacing before splicing
the display because the splice plates should not be loosened or moved after the display is
spliced.
Note: Do not tighten the offset extrusion at this time as it may need to be adjusted while
attaching the display to the structure..
12. After aligning the mounting brackets and
offset extrusion, verify the DMP and the ISP
enclosure will not experience interference
during installation. If they will experience
interference issues and need to be moved,
follow the directions in RelocatingaDigital
BillboardISPEnclosureandController in
AppendixA before hanging the display.
13. If the display has a vertical splice, either
from the factory or on site, locate the
horizontal splice tube at the splice location.
Refer to Figure3. This tube is shipped
installed and needs to be secure before
lifting the display. This tube also acts as an offset extrusion and can engage an upright. If
needed, before lifting the display, you can loosen and slide the splice tube until one of the
alternate alignment lines with the display splice. Tighten all splice tube bolts before lifting the
display.
14. Lift the display off of the truck.
15. Slowly lift the display to the structure head and guide into place with tag lines.
16. Lower the display along the uprights until it rests on the ledger brackets.
Note: The support ledger is provided by the customer prior to display installation. Refer to
Figure2.
17. Verify the display is resting on all ledger brackets. If the display is not resting on all ledger
brackets, shim the ledger bracket until it is in contact with the display. Refer to Figure4.

18. On each end of the display, slide the pre-assembled offset extrusion and the rocker clamps
over until they engage the upright flanges. Refer to Figure5.
19. Use an impact wrench and the torque
stick (provided in the spare parts box) to
tighten the nut on the rocker clamp bolt to
75 ft-lbs.
Note: If the U-channel mounted to the
offset extrusion bolt aligns with an
opening in the mounting channel, shift
the entire display left or right until the
U-channel is at least 1" from the opening.
20. Slide the right rocker mount into the end
of the offset extrusion.
21. Use an impact wrench and the torque
stick box to tighten the nut on the rocker
clamp to 75 ft-lbs.
22. Tighten all of the nuts on the offset
extrusion bolts to 75 ft-lbs with an impact
wrench and the torque stick.
23. Place and tighten all remaining mounting assemblies to 75 ft-lbs.
24. Remove the crane support.
25. Disconnect the tag lines.
26. Locate the top border cover caps.
