Installation Chapter 2
To comply with EN 55022 and EN 55024, use the following for cable types.
Installation Guidelines Follow these guidelines to make sure your computer provides safe and reliable service:
• 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 24 for further information. Never allow air passages
to become obstructed.
• The ambient air temperature must not exceed the maximum operating
temperature specified in Table 13 on page 110 . Consider a user-supplied
fan, heat exchanger, or air conditioner for heat generated by other devices
in the enclosure.
• The humidity of the ambient air must not exceed limits specified in
Table 13 on page 110 and must avoid condensation.
• The enclosure or cover must remain in place at all times during operation. The
cover provides protection against high voltages inside the computer and
inhibits radio-frequency emissions that can interfere with other equipment.

(1) Use the AC power cord shipped with the computer.
ATTENTION: To maintain an electrically safe installation, AC powered
computers must be plugged into a grounded outlet.
TIP Hot air rises. The temperature at the top of the enclosure is often
higher than the temperature in other parts of the enclosure, especially
if air is not circulating.
IMPORTANT The computer can operate at a range of extremes. However, the life
span of any electronic device is shortened if you continuously operate
the computer at its highest rated temperature.
