Fans are mounted in the bottom of the display for 8-32 high displays and in 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 maintenance (removal
and cleaning/replacement of the filter). Refer to
Drawing B-178625 or B-178626 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 (10.64" x 10.64" active area).
If these requirements are not met, the Galaxy display warranty may be void.
2.4 Lifting the Display
The top of the 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.
Do not attempt to permanently support the display by the eyebolts.
Figure 8: Lifting the Display (Correct, Left; Incorrect, Right)
If removing the eyebolts, adequately seal the holes using ½-13 bolts and sealing
washers. Silicone along the threads to ensure that water does not enter the display.
