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-EL/EM
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-EL/EM is being installed in a cabinet or control panel, always
provide 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.
