Daktronics AF-3112-34-R,A - Manual (Page 16)

There are nutserts provided on the back of the display for mounting of the display to
a structure. Use all the provided mounting nutserts when mounting the display.
If a mounting kit was ordered with the display, mount the channel to the display
using the nutserts on the back of the display.

For ventilation, fans are mounted in the back of the display. Maintain a minimum
distance of 3" (7.62cm) below the display to maintain proper airflow to the
ventilation inlets. Refer to Drawing A-193720 or A-201993 for your display size for
additional information.
If the display cabinet is completely enclosed:
• 13 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 structure, a minimum of 200 cfm is required for both inlet
and exhaust.
If these requirements are not met, the Galaxy ® display warranty may be void.
2.4 Lifting the Display
The top of 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.
