Daktronics Galaxy AF-3500 Series Double Face - Manual (Page 7)

Mechanical Installation 3
Section 2: Mechanical Installation
Read the Mechanical, Power and Signal Installation sections before installing the display(s).
Daktronics’ engineering staff must approve any changes that affect the weather-tightness of the display. Prior to
making any modifications, detailed drawings of the changes must be submitted to Daktronics for evaluation and
approval, or the warranty will be null and void.
Daktronics is not responsible for installations or the structural integrity of support structures done by others. The
customer must ensure a qualified structural engineer approves the structure and any additional hardware.
2.1 Pre-Installation Checklist
Verify the following before installation:
• The display is in good condition after shipping and uncrating.
• A straight and square mounting frame is provided for the display.
• Height variation in any 4'. (1.2 m) horizontal section must not exceed 1/4" (6.3 mm).
• Adequate support is provided for the display so that the structure will not yield at any unsupported
points after mounting.
• Leave 4" (10.2 cm) of unobstructed space above the display so the eyebolt can be removed.
No clearance is required once the eyebolt is removed.
• Maintain clearance around the display to allow unobstructed air flow through the vents and fans and to
allow access to internal components.
• Assure the display cabinet has no holes (accidental or intentional) that could allow water to enter the
display.
• Check that all display modules are fully latched into the display cabinet.
2.2 Support Structure Requirements
The installer must ensure that the mounting structure and hardware can support the display, and that the
structure follows all local codes.
Support structure design depends on the mounting methods, display size, and weight. Because every
installation site is unique, no single procedure is approved by Daktronics for mounting Galaxy
® displays.
The information contained in this section is general information only and may not be appropriate for all
installations. Refer to
Figure 2 and Figure 3 for basic display set ups.
Mounting plans need to take into account the ventilation system and face-mounted light sensor. In general,
the entire front of all displays must be completely unobstructed to allow for air flow and internal access.
Displays contain fans that pull air in from the lower vents and exhaust it out adjacent vents.
Also, keep in mind the location of mounting clips and the clearance needed for the power and signal
terminations on the back of the display. Display height and wind loading are also critical factors to consider.
Consult the Shop Drawing, which is included with the display.
