Precautions for Correct Use
• Do not operate the control system in the following locations. Operation may stop or malfunctions may
occur.
a) Locations subject to direct sunlight
b) Locations subject to temperatures or humidity outside the range specified in the specifications
c) Locations subject to condensation as the result of severe changes in temperature
d) Locations subject to corrosive or flammable gases
e) Locations subject to dust (especially iron dust) or salts
f) Locations subject to exposure to water, oil or chemicals
g) Locations subject to shock or vibration
• Take appropriate and sufficient countermeasures when installing the Controller in the following loca-
tions.
a) Locations subject to static electricity or other forms of noise
b) Locations subject to strong electromagnetic fields
c) Locations subject to possible exposure to radioactivity
d) Locations close to power lines
• Before touching a Unit, be sure to first touch a grounded metallic object in order to discharge any
static build-up.
• Use the rated power supply voltage for the Power Supply Units. Take appropriate measures to
ensure that the specified power with the rated voltage and frequency is supplied in places where the
power supply is unstable.
• Install the control system away from sources of heat and ensure proper ventilation. Not doing so may
result in malfunction, in operation stopping, or in burning.
• Use proper connection methods and EtherCAT communication cables. Otherwise, communications
may be faulty. Refer to
• Do not allow foreign matter to enter the openings in the Unit. Doing so may result in Unit burning,
electric shock, or failure.
• Do not allow wire clippings, shavings, or other foreign material to enter any Unit. Otherwise, Unit
burning, failure, or malfunction may occur. Cover the Units or take other suitable countermeasures,
especially during wiring work.
• Do not disconnect the EtherCAT slave cables during operation. The outputs will become unstable.
• 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 unfore-
seeable problems with the PLC System. Be sure that the operating environment is within the speci-
fied conditions at installation and remains within the specified conditions during the life of the system.
