Daktronics Galaxy AF-3500 Series 46 mm - Manual (Page 11)

Mechanical Installation 7
Natural Convection
RGB displays 40 pixels high and above use natural convection. RGB displays 40 and 48 high
have intake vents in the front bottom, and exhaust vents in the rear top. RGB displays 56 high
and above have intake and exhaust vents in the rear only.
Monochrome displays 48 high and above have intake and exhaust vents in the rear only.
Refer to Figure 8.
Note: To maintain safe operating temperatures in the display, do not close off the top or
bottom of the structure. The openings on the side of the structure do not help in cooling the
display adequately. Openings on the side of the structure cannot be considered “open area.”
If the natural airflow is blocked, the display will overheat and cause performance issues.
Daktronics cannot be held responsible for performance issues that occur due to obstructed
airflow.
