• 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, salt, or metal filings.
• Locations that would subject the PLC to direct shock or vibration.
• Locations exposed to direct sunlight.
• Locations that would subject the PLC to water, oil, or chemical reagents.
Be sure to enclose or protect the PLC sufficiently 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 lines.
When the PLC is being installed in a cabinet or control panel, be sure to pro-
vide proper ambient conditions as well as access for operation and mainte-
nance.
Temperature Control
The ambient temperature within the enclosure must be within the operating
range of 0°C to 55°C. When necessary, take the following steps to maintain
the proper temperature.
• Provide enough space for good air flow.
• Do not install the PLC above equipment that generates a large amount of
heat such as heaters, transformers, or high-capacity resistors.
• If the ambient temperature exceeds 55°C, install a cooling fan or air con-
ditioner.

• If a Programming Console will be left on the PLC, the ambient tempera-
ture must be within the Programming Console's operating range of 0°C to
45°C.
Accessibility for Operation and Maintenance
• To ensure safe access for operation and maintenance, separate the PLC
as much as possible from high-voltage equipment and moving machinery.
• The PLC will be easiest to install and operate if it is mounted at a height of
about 1.0 to 1.6 m.
