Installation Environment
This section details the necessary environmental conditions for installing the
PC.
Caution
Static electricity can damage PC components. Your 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.
Ambient Conditions
Do not install the PC in any of the following locations. Doing so will affect PC life
and may affect operating performance.
•
Locations subject to ambient temperatures lower than 0
°
C or higher than
55
°
C, or 0
°
C to 45
°
C when a Programming Console is used.
•
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.
Cooling
There are two points to consider in order to ensure that the PC does not over-
heat. The first is the clearance between the Racks, and the second is installation
of a cooling fan.
Clearance between Racks
The Racks need to have sufficient 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.
The Racks must also be mounted so that the total length of the Connecting
Cable between all Racks in a given series does not exceed 12 m. As a general
rule, about 70 to 120 mm should be left between any two Racks. Consider fac-
tors such as the width of the wiring duct, wiring length, ventilation, and ease of
access to Units, when determining the spacing between Racks. Greater space
is required between Racks when using certain CPU Bus and Special I/O Units.
Refer to the operation manuals for the Units you are using for details.
Cooling Fan
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 speci-
fied. If the PC is mounted in an enclosure, install a cooling fan, as shown in the
following diagram, to maintain the ambient temperature within specifications.
