Installation Chapter 2
Installation Guidelines Follow these guidelines to make sure that your computer provides service with
excellent reliability:
• The installation site must have sufficient power.
• In dry environments, static charges can build up easily. Proper grounding
of the computer helps to reduce static discharges, which can cause shock
and damage electronic components.
• The enclosure must allow sufficient space around air inlets and outlets to
provide the circulation necessary for cooling. See
Mounting Clearance
Requirements on page 22 for further information. Never allow air passages
to become obstructed.
• The ambient air temperature must not exceed the maximum operating
temperature as specified in Table 5 on page 59 . Consider a user-supplied
fan, heat exchanger, or air conditioner for heat that is generated by other
devices in the enclosure.
• The humidity of the ambient air must not exceed limits that are specified
in
Table 5 on page 59 and must avoid condensation.
• 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.
