Installation and Wiring Precautions
Always consider the following factors when installing and wiring the PLC to
improve the reliability of the system and make the most of the CP1L functions.
Ambient Conditions
Do not install the PLC in any of the following locations.
• 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.
Always 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.
Installation in
Cabinets or Control
Panels
When the CP1L is being installed in a cabinet or control panel, always provide
proper ambient conditions as well as access for operation and maintenance.
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.
