SAFETY PRECAUTIONS

(Read these precautions before use.)

Before using this product, please read this manual and the relevant manuals introduced in this manual carefully and pay full

attention to safety in order to handle the product correctly.

This manual classifies the safety precautions into two categories: [ WARNING] and [ CAUTION].

Depending on the circumstances, procedures indicated by [ CAUTION] may also cause severe injury.

It is important to follow all precautions for personal safety.

Store this manual in a safe place so that it can be read whenever necessary. Always forward it to the end user.

[DESIGN PRECAUTIONS]

WARNING

●Make sure to set up the following safety circuits outside the PLC to ensure safe system operation

even during external power supply problems or PLC failure. Otherwise, malfunctions may cause

serious accidents.

- Most importantly, set up the following: an emergency stop circuit, a protection circuit, an interlock

circuit for opposite movements (such as normal vs. reverse rotation), and an interlock circuit (to

prevent damage to the equipment at the upper and lower positioning limits).

- Note that when the CPU module detects an error, such as a watchdog timer error, during self-

diagnosis, all outputs are turned off. Also, when an error that cannot be detected by the CPU

module occurs in an input/output control block, output control may be disabled. External circuits

and mechanisms should be designed to ensure safe machinery operation in such a case.

- Note that the output current of the 24 V DC service power supply varies depending on the model

and the absence/presence of extension modules. If an overload occurs, the voltage automatically

drops, inputs in the PLC are disabled, and all outputs are turned off. External circuits and

mechanisms should be designed to ensure safe machinery operation in such a case.

- Note that when an error occurs in a relay, transistor or triac of an output circuit, the output might

stay on or off. For output signals that may lead to serious accidents, external circuits and

mechanisms should be designed to ensure safe machinery operation in such a case.

●Construct an interlock circuit in the program so that the whole system always operates on the safe

side before executing the control (for data change) of the PLC in operation.

Read the manual thoroughly and ensure complete safety before executing other controls (for program

change, parameter change, forcible output and operation status change) of the PLC in operation.

Otherwise, the machine may be damaged and accidents may occur due to erroneous operations.

●In an output circuit, when a load current exceeding the current rating or an overcurrent caused by a

load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an

external safety circuit, such as a fuse.

●For the operating status of each station after a communication failure of the network, refer to relevant

manuals for the network. Incorrect output or malfunction may result in an accident.

●To maintain the safety of the programmable controller system against unauthorized access from

external devices via the network, take appropriate measures. To maintain the safety against

unauthorized access via the Internet, take measures such as installing a firewall.

WARNING

Indicates that incorrect handling may cause hazardous conditions, resulting in

death or severe injury.

CAUTION

Indicates that incorrect handling may cause hazardous conditions, resulting in

minor or moderate injury or property damage.

[DESIGN PRECAUTIONS]

[INSTALLATION PRECAUTIONS]

CAUTION

●When an inductive load such as a lamp, heater, or solenoid valve is controlled, a large current

(approximately ten times greater than normal) may flow when the output is turned from off to on. Take

proper measures so that the flowing current does not exceed the value corresponding to the

maximum load specification of the resistance load.

●After the CPU module is powered on or is reset, the time taken to enter the RUN status varies

depending on the system configuration, parameter settings, and/or program size.

Design circuits so that the entire system will always operate safely, regardless of this variation in time.

●Simultaneously turn on and off the power supplies of the CPU module and extension modules.

●If a long-time power failure or an abnormal voltage drop occurs, the PLC stops, and output is turned

off. When the power supply is restored, it will automatically restart (when the RUN/STOP/RESET

switch is on RUN side).

WARNING

●Make sure to cut off all phases of the power supply externally before attempting installation or wiring

work. Failure to do so may cause electric shock or damage to the product.

●Use the product within the generic environment specifications described in the generic specifications

of the user's manual (Hardware) of the CPU module to use.

Never use the product in areas with excessive dust, oily smoke, conductive dusts, corrosive gas (salt

air, Cl2, H2S, SO2or NO2), flammable gas, vibration or impacts, or expose it to high temperature,

condensation, or rain and wind.

If the product is used in such conditions, electric shock, fire, malfunctions, deterioration or damage

may occur.

[INSTALLATION PRECAUTIONS]

CAUTION

●Do not touch the conductive parts of the product directly. Doing so may cause equipment failures or

malfunctions.

●When drilling screw holes or wiring, make sure that cutting and wiring debris do not enter the

ventilation slits of the PLC. Failure to do so may cause fire, equipment failures or malfunctions.

●For product supplied together with a dust proof sheet, the sheet should be affixed to the ventilation

slits before the installation and wiring work to prevent foreign objects such as cutting and wiring

debris.

However, when the installation work is completed, make sure to remove the sheet to provide

adequate ventilation. Failure to do so may cause fire, equipment failures or malfunctions.
