This section details the necessary environmental conditions for installing the
PC. Proper installation procedures and a proper environment are essential to
getting the best performance and reliability from your PC.
Static electricity can damage PC components. Your body can carry an electros-
tatic 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 affect PC life
and may adversely affect operating performance.
• Locations subject to direct sunlight.
• Locations subject to ambient temperatures lower than 0°C or higher than 55°C
(or higher than 45°C when using a Programming Console).
• Locations subject to ambient humidity lower than 35% or higher than 85%.
• Locations subject to condensation as the result of severe changes in tempera-
ture.
• Locations subject to corrosive or flammable gases.
• Locations subject to dust (especially iron dust) or salts.
• Locations subject to shock or vibration.
• Locations subject to exposure to water, oil, or chemicals.
• Take appropriate and sufficient countermeasures when installing systems in
the following locations.
• Locations subject to static electricity or other forms of noise.
• Locations subject to strong electromagnetic fields.
• Locations subject to possible exposure to radioactivity.
• Locations close to power supplies.
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.
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.
