The method used to mount displays can vary greatly from location to location. For
this reason, only general mounting topics can be addressed in this manual.
It is the responsibility of the installer to ensure the installation will adequately
meet local codes and standards, as well as the mounting hardware and method.
Before beginning the installation process, verify the following items:
• The mounting structure will provide a straight and square-mounting 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 is equipped with 2 x 2 x 3 x ¼" steel clip angles. Refer to
Drawing B-183660. These angles may be used for mounting purposes. Remember to
have all mounted displays inspected by a qualified structural engineer. Daktronics
recommends using all clip angles as attachment points.
Refer to Drawing B-183660 for a suggested wall mount method. The number of
attachment points needed and the wall structure must be reviewed by a qualified
structural engineer and meet all national and local codes. It is the customer’s
responsibility to determine the proper wall mounting method and location.
1. Carefully uncrate the display. Look each side of the display over for
possible damage during shipping.
2. Following the guidelines described in Section 2.4, lift the display into
position on the support structure.
3. Weld or use ½" Grade-5 bolts and hardware to secure the clip angles to the
support structure as shown in Drawing B-183660.
4. Refer to Section 3 for information on routing power and signal.
5. After installation is complete, carefully inspect the display for any holes
that may allow water to seep into the display. Seal any openings with
silicone. If the eyebolts on the top of the display have been removed, plug
the holes with bolts and the rubber-sealing washer that was removed with
the eyebolt.
2.6 Optional Temperature Sensor Mounting
If an optional temperature sensor will be used with this display, see Appendix C for
