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 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 display uses 3x2x
3
/
8
" steel clip angles at the locations shown in the
Shop Drawings . These angles assist in mounting the display. Remember to have all
mounted displays 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 each side of the display over for
possible damage cased 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 Shop Drawings . Refer to
Section 3 for information on routing power and signal.
4. (For 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 the
Shop Drawings . Connect power and signal (refer
to Drawings A-175194 , A-184111 , and B-184326 ). The sign is then ready
for installation.
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.
