Daktronics AF-3165-34-RGB - Manual (Page 16)

Mechanical Installation 2-2
Before beginning the installation process, verify the following:
• The mounting structure will provide a straight and square-mounting frame
for the display
• The mounting structure is capable of supporting the display and will not
yield at any unsupported points after mounting
• Clearance: 3" of unobstructed space is available below the display for filter
removal from the display. 1-¼" of unobstructed space is available above the
top of the display to remove the eyebolt and plug the hole properly
Correct any deficiencies before installation.
2.3 Ventilation Requirements

Fans are mounted in the bottom of the display for 8-32 high displays and to the back
sheet for ventilation on the 40 and 48 high displays. Maintain a minimum distance of
3" (7.62cm) below the display to maintain proper airflow and for easy air filter
removal. Refer to Drawing B-172745 or B-172746 for additional information.
If the display cabinet is completely enclosed:
• 6 square inches of unobstructed opening per module must be provided to
ensure adequate cooling.
• Allowances must be made to compensate for the percentage of material
covering the openings in the structure.
• For adequate cooling, forced ventilation may be required. If air is forced
into the enclosed cabinet, 10 cubic feet per minute must be provided per
module (10.6" x 10.6" active area).
If these requirements are not met, the Galaxy
®
display warranty may be void.
2.4 Lifting the Display
The top of the larger displays is equipped with eyebolts that are used to lift the unit.
Take special care to ensure that the rated load of the eyebolts is not exceeded. Refer
to the information at the end of this section labeled Eyebolts to determine the
allowable load of the eyebolts shipped with the display.
Figure 8 below illustrates both the correct (left example) and the incorrect (right
example) method of lifting a display. Lift the display as shown on the left, with the
lifting bar. Use every lifting point provided.
