2-2 Mechanical Installation
1. Inspect the top and sides of the display for any holes that may allow moisture to enter the display.
If the eyebolts were removed, plug the holes with bolts and the rubber sealing washer that came
with the eyebolt.
2. Plug and seal the eyebolt holes and any other openings that may allow water to enter the display
with silicone or another waterproof sealant.

CAUTION: Fully attach backsheets to the display cabinet with all of the screws prior to
lifting the display with the eye bolts. The backsheets provide structural support to the cabinet.
Lifting the display with the backsheets removed may cause the cabinet members to twist,
compromising the structural integrity and/or squareness of the display frame. If the display
frame is not square, normal waterproofing measures may prove inadequate, leading to moisture
related problems for the electronics.
2.3 Cabinet Mounting
Reference Drawing:
Mounting Example, 2½ ˝ Small Matrix ....................................................Drawing A-114676
The method used to mount displays can vary greatly from location to location. For this reason, this
manual only addresses general mounting topics. If this display was part of a custom contract, consult
the shop drawing in Appendix A for mounting information.
Before beginning the installation process, verify the following:
• The mounting structure will provide a straight and square frame for mounting the display.
• The mounting structure will not give way at any unsupported points after mounting the display.
Correct any deficiencies before beginning the installation process.
It is the responsibility of the installer to ensure the installation will agree with local codes. The
mounting hardware is also the responsibility of the installer.
The 9 x 1¾ x 1¾ channel used in this display requires supporting the display every eight feet with a
maximum overhang of three feet on each end of the display. The distribution of these supports is to be
symmetrical. This requires a minimum of two supports.
Drawing A-114676 illustrates one of the many ways a small matrix display may be mounted. To
mount a display as seen in the drawing complete the following steps:
1. Remove the four pieces of bar stock from the display. These flat pieces of metal reinforce the
display cabinet at the mounting points.
2. Since bolts or rods will be run on each side of each
column, it will be necessary to drill two holes in both the
bar stock and the cabinet frame at the support points.
Refer to Figure 25.
3. Drill holes in the bar stock and through the cabinet frame.
Run bolts to the angles on the opposite side of the
columns.
4. Secure the display firmly in place.
