The method used to mount signs 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
sign. 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 sign is mounted.
The back of the sign uses 2x2x1/4" steel clip angles at the locations shown in
Drawing B-163291 and Drawing B-163293 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 sign. Look each side of the sign over for damage
during shipping.
2. Following the guidelines described in Section 2.4 , lift the sign 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 Drawing B-163291 and
Drawing B-163293 .
4. Refer to Section 3 for information on routing power and signal.
5. Upon completing the installation, carefully inspect the sign for any holes
that may allow water to seep into the sign. Seal any openings with silicone.
If you remove the eyebolts on the top of the sign, plug the holes with bolts
and the rubber sealing washers that you removed with the eyebolts. Silicone
the threads on the bolts.
