Doing so may result in electric shock.xivOperating Environment Precautions4! WARNING Always ground the system to 100 Ω or less when installing the Units. Notconnecting to a ground of 100 Ω or less may result in electric shock.! WARNING Provide safety measures in external circuits (i.e., not in the ProgrammableController), including the following items, to ensure safety in the system if anabnormality occurs due to malfunction of the PC or another external factoraffecting the PC operation.

Not doing so may result in serious accidents.• Emergency stop circuits, interlock circuits, limit circuits, and similar safetymeasures must be provided in external control circuits.• The PC will turn OFF all outputs when its self-diagnosis function detects anyerror or when a severe failure alarm (FALS) instruction is executed. As a countermeasure for such errors, external safety measures must be provided to ensure safety in the system.• The PC outputs may remain ON or OFF due to deposition or burning of theoutput relays or destruction of the output transistors. As a countermeasure forsuch problems, external safety measures must be provided to ensure safety inthe system.• When the 24-VDC output (service power supply to the PC) is overloaded orshort-circuited, the voltage may drop and result in the outputs being turnedOFF.

As a countermeasure for such problems, external safety measures mustbe provided to ensure safety in the system.! WARNING When handling the Memory Backup Battery, never drop, disassemble, distort,short-circuit, recharge, heat to a temperature exceeding 100°C, or throw intofire. The Battery may explode, catch fire, or leak fluid if mishandled in any ofthese ways.4! CautionExecute online edit only after confirming that no adverse effects will be causedby extending the cycle time. Otherwise, input signals may not be readable.! CautionWhen transferring programs to other nodes, or when making changes to I/Omemory, confirm the safety of the destination node before transfer. Not doing somay result in injury.! CautionTighten the screws on the terminal block of the AC Power Supply Unit to thetorque specified in the operation manual.

The loose screws may result in fire ormalfunction.Operating Environment Precautions! CautionDo not operate the control system in the following places:• Locations subject to direct sunlight.• Locations subject to temperatures or humidity outside the range specified inthe 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.xvOperating Environment Precautions4• Locations subject to shock or vibration.! CautionTake appropriate and sufficient countermeasures when installing systems in thefollowing 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.! CautionxviThe operating environment of the PC System can have a large effect on the longevity and reliability of the system.

Improper operating environments can lead tomalfunction, failure, and other unforeseeable problems with the PC System. Besure that the operating environment is within the specified conditions at installation and remains within the specified conditions during the life of the system.5Application Precautions5Application PrecautionsObserve the following precautions when using the PC System.! CautionFailure to abide by the following precautions could lead to faulty operation of thePC or the system, or could damage the PC or PC Units.

Always heed these precautions.Designing Circuits or Creating Ladder Programs• Fail-safe measures must be taken by the customer to ensure safety in theevent of incorrect, missing, or abnormal signals caused by broken signal lines,momentary power interruptions, or other causes.• Construct a control circuit so that power supply for the I/O circuits does notcome ON before power supply for the Unit. If power supply for the I/O circuitscomes ON before power supply for the Unit, normal operation may be temporarily interrupted.• If the operating mode is changed from RUN or MONITOR mode to PROGRAMmode, with the IOM Hold Bit ON, the output will hold the most recent status. Insuch a case, ensure that the external load does not exceed specifications.

(Ifoperation is stopped because of an operating error, including errors generatedby FALS instructions, the values in the internal memory of the CPU Unit will besaved, but the outputs will all turn OFF.)• For models with only the super-capacitor installed, the contents of the READ/WRITE enable area of the DM area, HR area, AR area, and CNT data areamay be damaged if the power is turned OFF for a long time. To prevent suchdamage, provide ladder program that will check AR 1314 to ensure proper operation of the system.• The life of relays largely varies depending on switching conditions. Be sure totest operating conditions using actual Units and use the product within the specified number of switchings so as not to cause any performance problems.

Using the product with performance problems may result in defective insulationbetween circuits or burning of the relays.InstallationWiring and Connection• Install the Units properly as specified in the relevant operation manual(s). Improper installation of the Units may result in malfunction.• Do not install the PC or PC Units in places where the Units may be affected byexcessive noise.

Doing so may result in malfunction.• Install the Units properly so that they will not fall off.• Be sure that all the mounting screws, terminal screws, and cable connectorscrews are tightened to the torque specified in the relevant manuals. Incorrecttightening torque may result in malfunction.• Install the Expansion I/O Unit connector cover to the last Expansion I/O Unit toprevent dust or foreign matter from entering inside the Unit.

Not doing so mayresult in malfunction.• Be sure that the terminal blocks, expansion cables, and other items with locking devices are properly locked into place. Improper locking may result in malfunction.• Be sure to use cables as specified in the relevant manual(s).• Install external breakers and take other safety measures against short-circuiting in external wiring. Insufficient safety measures against short-circuiting mayresult in burning.• When wiring signal lines, do not place them in the same duct as high-voltagelines or power lines. Doing so may result in malfunction.xvii5Application Precautions• Be sure that terminal blocks and connectors are connected in the specifieddirection with the correct polarity. Not doing so may result in malfunction.• Leave the labels attached CPM1 or CPM2A Units when wiring to prevent wiring cuttings from entering the Units.• Attach the labels supplied with CPM1A or CPM2C Units or provide other protective covers when wiring to prevent dust or wiring cuttings from entering theUnits.• Remove the labels after the completion of wiring to ensure proper heat dissipation.

Leaving the labels attached may result in malfunction.• Use the connectors and wiring materials specified in the relevant manual(s).• Be sure to wire according to the relevant manual(s). Incorrect wiring may resultin burning.I/O Connection and System Startup• Disconnect the functional ground terminal when performing withstand voltagetests.• Always use the power supply voltages specified in the operation manual(s).
