Operating Environment Precautions
4
!Caution
Tighten the screws on the terminal block of the AC Power Supply Unit to the
torque specified in the operation manual. The loose screws may result in
burning or malfunction.
!Caution
Do not touch the Power Supply Unit when power is being supplied or immedi-
ately after the power supply is turned OFF. The Power Supply Unit will be hot
and you may be burned.
!Caution
Be careful when connecting personal computers or other peripheral devices
to a PLC to which is mounted a non-insulated Unit (CS1W-CLK12/52(-V1) or
CS1W-ETN01) connected to an external power supply. A short-circuit will be
created if the 24 V side of the external power supply is grounded and the 0 V
side of the peripheral device is grounded. When connecting a peripheral
device to this type of PLC, either ground the 0 V side of the external power
supply or do not ground the external power supply at all.

Operating Environment Precautions
!Caution
Do not operate the control system in the following locations:
• Locations subject to direct sunlight.
• Locations subject to temperatures or humidity outside the range specified
in the specifications.
• Locations subject to condensation as the result of severe changes in tem-
perature.
• Locations subject to corrosive or flammable gases.
• Locations subject to dust (especially iron dust) or salts.
• Locations subject to exposure to water, oil, or chemicals.
• Locations subject to shock or vibration.
!Caution
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.
!Caution
The operating environment of the PLC System can have a large effect on the
longevity and reliability of the system. Improper operating environments can
lead to malfunction, failure, and other unforeseeable problems with the PLC
System. Be sure that the operating environment is within the specified condi-
tions at installation and remains within the specified conditions during the life
of the system.

Application Precautions
Observe the following precautions when using the PLC System.
• You must use the CX-Programmer (programming software that runs on
Windows) if you need to program more than one task. A Programming
Console can be used to program only one cyclic task plus interrupt tasks.
