SAFETY PRECAUTIONS
(Read these precautions before using this product.)
Before using this product, please read this handbook and the relevant manuals introduced in this handbook
carefully and pay full attention to safety to handle the product correctly.
The precautions given in this handbook are concerned with this product only. For the safety precautions of
the programmable controller system, refer to the user's manual for the CPU module used.
In this manual, the safety precautions are classified into two levels: " WARNING" and " CAUTION".
Under some circumstances, failure to observe the precautions given under " CAUTION" may lead to
serious consequences.
Observe the precautions of both levels because they are important for personal and system safety.
Make sure that the end users read this handbook and then keep the handbook in a safe place for future
reference.
[Design Precautions]
WARNING
●For the operating status of each station after a communication failure, refer to the manuals for the
stations used.
Incorrect output or malfunction due to a communication failure may result in an accident.
●When connecting a peripheral with the CPU module or connecting a personal computer with an
intelligent function module to modify data of a running programmable controller, configure an
interlock circuit in the program to ensure that the entire system will always operate safely.
For other forms of control (such as program modification or operating status change) of a running
programmable controller, read the relevant manuals carefully and ensure that the operation is safe
before proceeding.
Especially, when a remote programmable controller is controlled by an external device, immediate
action cannot be taken if a problem occurs in the programmable controller due to a communication
failure.
To prevent this, configure an interlock circuit in the program, and determine corrective actions to be
taken between the external device and CPU module in case of a communication failure.
●Do not write any data to the "system area" of the buffer memory in the intelligent function module.
Also, do not use any "use prohibited" signal as an output signal from the CPU module to the
intelligent function module.
Doing so may cause malfunction of the programmable controller system.
WARNING
CAUTION
Indicates that incorrect handling may cause hazardous conditions,
resulting in death or severe injury.
Indicates that incorrect handling may cause hazardous conditions,
resulting in minor or moderate injury or property damage.

[Design Precautions]
[Installation Precautions]
[Installation Precautions]
[Wiring Precautions]
CAUTION
●Do not install the control lines or communication cables together with the main circuit lines or power
cables.
Keep a distance of 100mm or more between them.
Failure to do so may result in malfunction due to noise.
WARNING
●Shut off the external power supply (all phases) used in the system before connecting or
disconnecting a module.
Failure to do so may result in electric shock or cause the module to fail or malfunction.
CAUTION
●Use the programmable controller in an environment that meets the general specifications in the
Safety Guidelines provided with the CPU module or head module.
Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the
product.
●To interconnect modules, engage the respective connectors and securely lock the module joint
levers.
Incorrect interconnection may cause malfunction, failure, or drop of the module.
●Do not directly touch any conductive parts and electronic components of the module.
Doing so can cause malfunction or failure of the module.
WARNING
●Shut off the external power supply (all phases) used in the system before wiring.
Failure to do so may result in electric shock or cause the module to fail or malfunction.
●After installation and wiring, attach the included terminal cover to the module before turning it on for
operation.
Failure to do so may result in electric shock.

A- 3
[Wiring Precautions]
CAUTION
●Use applicable solderless terminals and tighten them within the specified torque range.
If any spade solderless terminal is used, it may be disconnected when a terminal block screw comes
loose, resulting in failure.
●Connectors for external devices must be crimped or pressed with the tool specified by the
manufacturer, or must be correctly soldered.
Incomplete connections may cause short circuit, fire, or malfunction.
●Securely connect the connector to the module.
●Place the cables in a duct or clamp them.
If not, dangling cable may swing or inadvertently be pulled, resulting in damage to the module or
cables or malfunction due to poor contact.
●Check the interface type and correctly connect the cable. Incorrect wiring (connecting the cable to an
incorrect interface) may cause failure of the module and external device.
●Tighten the terminal block screws within the specified torque range.
Undertightening can cause short circuit, fire, or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, fire, or
malfunction.
●When disconnecting the cable from the module, do not pull the cable by the cable part.
For the cable with connector, hold the connector part of the cable.
For the cable connected to the terminal block, loosen the terminal screw.
Pulling the cable connected to the module may result in malfunction or damage to the module or
cable.
●Prevent foreign matter such as dust or wire chips from entering the module.
Such foreign matter can cause a fire, failure, or malfunction.
●A protective film is attached to the top of the module to prevent foreign matter, such as wire chips,
from entering the module during wiring.
Do not remove the film during wiring.
Remove it for heat dissipation before system operation.

[Startup and Maintenance Precautions]
[Operating Precautions]
[Disposal Precautions]
WARNING
●Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction.
●Shut off the external power supply (all phases) used in the system before cleaning the module or
retightening the terminal block screws.
Failure to do so may result in electric shock.
CAUTION
●Do not disassemble or modify the modules. Doing so may cause failure, malfunction, injury, or a fire.
●Shut off the external power supply (all phases) used in the system before connecting or
disconnecting a module.
Failure to do so may cause the module to fail or malfunction.
●Tighten the terminal block screws within the specified torque range.
Undertightening can cause drop of the component or wire, short circuit, or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
●After the first use of the product (module and terminal block), the number of connections/
disconnections is limited to 50 times (in accordance with IEC 61131-2).
Exceeding the limit may cause malfunction.
●Before handling the module, touch a conducting object such as a grounded metal to discharge the
static electricity from the human body.
Failure to do so may cause the module to fail or malfunction.
CAUTION
●When changing data and operating status, and modifying program of the running programmable
controller from a personal computer connected to an intelligent function module, read relevant
manuals carefully and ensure the safety before operation.
Incorrect change or modification may cause system malfunction, damage to the machines, or
accidents.
●While set values in the buffer memory are being registered to the flash ROM in the module, do not
power off the station where the module is mounted or do not reset the CPU module.
Doing so will affect the flash ROM data, and setting to the buffer memory and registration to the flash
ROM need to be performed again.
Also, it may cause failure or malfunction of the module.
CAUTION
●When disposing of this product, treat it as industrial waste.
