• The
ambient air temperature must not exceed the maximum operating temperature in
Environmental Specifications on page 29
. Consider a user-supplied fan, heat exchanger,
or air conditioner for heat that is generated by other devices in the enclosure.
• The relative humidity of the ambient air must not exceed limits in
• The enclosure or cover must always remain in place during operation. The cover provides
protection against high voltages inside the computer and inhibits radio frequency
emissions that can interfere with other equipment.
• When mounted, the computer cannot be tilted from vertical.
TIP
Hot air rises. The temperature at the top of the enclosure is often higher than the
temperature in other parts of the enclosure, which is likely if air is not circulating.
IMPORTANT
The computer can operate at a range of extremes. If you continuously operate the
computer at its highest rated temperature, then the life span of any electronic
device is shortened, which includes the touch screen and LCD panel.
