5-1 Installation Environment
This section details the necessary environmental conditions for installing the
PC.
Caution Static
electricity can
damage PC components. Y
our body can carry an electro
-
static charge, especially when the humidity is low. Before touching the PC, be
sure
to first touch a grounded metallic object, such as a metal water pipe, in order
to discharge any static build-up.
Do
not install the PC in any of the following locations. Doing so will af
fect PC life
and may affect operating performance.
• Locations subject to ambient temperatures lower than 0°C or higher than
55°C.
• Locations subject to drastic temperature changes or condensation.
• Locations subject to ambient humidity lower than 10% or higher than 90%.
• Locations subject to corrosive or flammable gases.
• Locations subject to excessive dust (especially iron dust) or chloride.
• Locations that would subject the CPU to direct shock or vibration.
• Locations that would subject the PC to water, oil, or chemical reagents.
• Locations exposed to direct sunlight.
There
are two points to consider in order to
ensure that the PC does not over
-
heat.
The first is the clearance between Racks, and the second is installation of
a
cooling fan.
The
Racks need to have suf
ficient room between each other to allow for I/O wir
-
ing,
and additional room to ensure that the I/O wiring does not hamper cooling.
However, the Racks must be mounted close enough to each other that the
length
of the Connecting Cable between any two Racks does not exceed 10 m,
and the total length of the Connecting Cables between all Racks does not ex-
ceed
12 m. As a general rule, about 70 to120 mm should be left between any two
Racks.
A
cooling fan is not always necessary
, but may be needed in some installations.
Try
to avoid mounting the PC in a warm area, or over a source of heat. A cooling
fan
is needed if the ambient temperature may become higher than that
specified
(refer
to
Appendix B Specifications
). If the PC is mounted in an enclosure, a cool
-
ing
fan may need to be installed, as shown below
, to maintain the ambient tem
-
perature within specifications.
