Do not install your PLC system if any of the following
conditions are present.
• Ambient temperature outside the range of 0 to 55° C
(32 to 131° F).
• Direct sunlight.
• Humidity outside the range of 30% to 85% (non-
condensing)
• Chemicals that may affect electronic parts.
• Excessive or conductive dust, or salinity.
• High voltage, strong magnetic fields, or strong
electromagnetic influences.
• Direct impact and excessive vibration.
Electrostatic Discharges
Under dry condition, excessive electrostatic discharges
may occur. Make sure to remove electrostatic discharges
by touching a grounded metal piece before touching your
controller system modules.
Cleaning
Never use chemicals such as thinner because they melt,
deform or discolor PCB boards.
Precautions for use of power
• Run your PLC system only after the I/O devices and
motor devices have started. (For example, first power
on in the PROG mode, then change the operation mode
to RUN.)
• Make sure to power off I/O devices after ensuring PLC
operation is stopped.
If you power on/off I/O devices when the PLC system is
in operation, the system may malfunction because input
signal noises may be recognized as normal inputs.
