Selecting an Enclosure

.
Stirring fans or active cooling be required in high altitude and high ambient
temperature locations to keep the internal enclosure temperature below
55 °C (131 °F). Use a heater in installations where the ambient temperature is
below 0 °C (32 °F).
Backlight Considerations
The backlight of the high-bright display generates a significant amount of heat
when set to full intensity. To minimize the amount of heat generated and extend
the life of the backlight, decrease the display intensity by using the screen saver
with a 5…10 minute delay.
Orientation of the Terminal
If outside, avoid placing the terminal on the south (north in the southern
hemisphere) or west side of a cabinet, if possible. This reduces the heat rise due to
solar loading during the hottest part of the day.
Mount the terminal vertically to minimize solar loading on the display. Do not
mount the terminal in a sloped enclosure if it is exposed to direct sunlight.
