2.5 Sign Mounting

Shop Drawings........................................................................ Appendix A
The method used to mount displays varies greatly from location to location. For this
reason the manual covers only general mounting topics.
The installer is responsible to ensure the installation will adequately meet local
codes and standards. The installer is also responsible for the mounting method
and hardware.
Before beginning the installation process, verify the following items:
• The mounting structure will provide a straight and square frame for the
display. Height variation in any four-foot horizontal section may not exceed
¼- inch.
• The mounting structure will not give way at any unsupported points after
the display is mounted.
The back of the display uses 3x2x
3
/
8
" steel clip angles at the locations shown in the
Shop Drawings. These angles assist in mounting the sign. Remember to have all
mounted signs inspected by a qualified structural engineer.
The customer must have a qualified structural engineer review the number of
attachment points needed and the wall structure to ensure both meet all national and
local codes. Daktronics recommends using all clip angles as attachment points.
1. Carefully uncrate the display. Look all sides of the displays over for damage
during shipping.
2. Following the guidelines described in Section 2.4, lift the display into
position on the support structure using all provided eyebolts.
3. Weld or use ½" Grade-5 bolts and hardware to secure the clip angles to the
support structure as shown in Top View in the Shop Drawings. Refer to
Section 3 for information on routing power and signal.
4. (For 40 and 48 high Sectional Displays Only): Remove lift eyes from the
bottom section. Using all lift eyes provided, lift the top section over the
bottom section. Align the holes as required for 5/8" hardware. Secure
sections using 5/8" hardware, as shown in Shop Drawings. Connect power
using the mate-n-loc plugs provided with the display. Connect the signal by
routing the ribbon cable from the controller to the first driver in the row of
modules for those rows in the top section.
5. Upon completing the installation, carefully inspect the display for any holes
that may allow water to seep into the display. Seal any openings with
silicone. If you remove the eyebolts on the top of the display, plug the holes
with bolts and the rubber sealing washers that you removed with the
eyebolts. Silicone the threads on the bolts.
