INSTRUCTION SHEET
General Precautions
You must allow sufficient leeway in ratings and performance and provide proper fail-safe and other safety
measures when using the Unit in any of the following applications. Be sure also to consult with your
OMRON representative before actually attempting any of these applications.
• Applications under conditions or environments not specified in the relevant manuals.
• Applications for nuclear reactor control, train facilities, aviation facilities, motorized vehicles, fur-
naces, medical equipment, amusement equipment, and safety equipment.
• Applications strongly related to human life or property, particularly those requiring safety.
Safety Precautions
Definition of Precautionary Information
WARNING Indicates a potentially hazardous situation which, if not avoided, could result
in death or serious injury.
Caution Indicates a potentially hazardous situation which, if not avoided, may result in
minor or moderate injury, or property damage.
Warnings
WARNING Do not attempt to take the Unit apart and do not touch any internal parts while
the power is being supplied. Doing either of these may result in electric shock.
Caution Make sure that communications connector screws are tightened to a torque
of 0.5 to 0.6 N⋅m and terminal screws and cassette mounting screws to a
torque of 0.3 to 0.6 N⋅m. Incorrect tightening torque may result in malfunction.
Application Precautions
• Do not attempt to disassemble, repair, or modify the Units in any way. Doing so may result in elec-
tric shock.
• Do not drop the product or subject it to excessive shocks or vibrations. Doing so may result in
malfunction.
• Mount the Unit securely to a DIN track or mounting brackets. Not mounting the Unit securely may
result in malfunction.
• Always turn OFF the power supply before mounting or dismounting the cassette. Not turning OFF
the power supply may result in malfunction.
• Use specified communications cables.
• Keep within the specified ranges when performing wiring for communications. Incorrect wiring may
result in burning.
• Separate communications cables from power lines or high-voltage lines.
• Do not pull on the cables or bend the cables beyond their natural limit. Doing either of these may
break the cables.
• Fail-safe measures must be taken by the customer to ensure safety in the event of incorrect, mis-
sing, or abnormal signals caused by broken signal lines, momentary power interruptions, or other
causes. Failing to take appropriate measures may result in injury.
• Double-check all the wiring before turning ON the power supply. Incorrect wiring may result in
burning.
• Use crimp terminals for wiring. . Do not connect bare stranded wires directly to terminals. Connec-
tion of bare stranded wires may result in burning.
• Pay attention to the terminal polarity and voltage ranges for I/O connections when wiring the com-
munications lines and power supply lines. Not doing so may result in malfunction.
• Always use the power supply voltage specified in this document. An incorrect voltage may result in
malfunction or burning.
• 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. An incorrect power supply may result in
malfunction.
Operating Environment Precautions
• Install the Unit properly as specified in the relevant manuals. Improper installation of the Unit may
result in malfunction.
• Do not install the Unit in the following places:
• 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 temperature
• 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
• 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
• Never use volatile solvents, such as benzene or thinners, or chemical dusters. Otherwise the Unit
may malfunction.
• Separate communications power lines from I/O power lines or power lines used for driving loads.
