SAFETY PRECAUTIONS
(Read these precautions before using this product.)
Before using this product, please read this manual and the relevant manuals carefully and pay full attention
to safety to handle the product correctly.
In this manual, the safety precautions are classified into two levels: " WARNING" and "
CAUTION".
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.
Under some circumstances, failure to observe the precautions given under "
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 manual and then keep the manual in a safe place for future
reference.
CAUTION" may lead to
[Design Precautions]
WARNING
● When connecting a peripheral with the programmable controller CPU or connecting a personal
computer with an intelligent function module to modify data of a running programmable controller,
configure an interlock circuit in the sequence 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" in the buffer memory of 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 these operations may cause malfunctions to the programmable controller system.
● Provide security measures on user side that prevent unauthorized access from outside via network
as necessary.

[Installation Precautions]
CAUTION
● Use the programmable controller in an environment that meets the general specifications in the
user's manual for the CPU module used.
Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the
product.
● To mount the module, while pressing the module mounting lever located in the lower part of the
module, fully insert the module fixing projection(s) into the hole(s) in the base unit and press the
module until it snaps into place.
Incorrect mounting may cause malfunction, failure or drop of the module.
When using the programmable controller in an environment of frequent vibrations, fix the module
with a screw.
Tighten the screws within the specified torque range.
Undertightening can cause drop of the screw, short circuit, or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
● Shut off the external power supply (all phases) used in the system before mounting or removing the
module.
Failure to do so may result in damage to the product.
● Do not directly touch any conductive parts and electronic components of the module.
Doing so can cause malfunction or failure of the module.

[Wiring Precautions]
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 damage to the product.
● 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.
CAUTION
● Place the communication cable or power cable in a duct or clamp it.
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 type of the interface to be connected before wiring the modules.
Connecting to a wrong interface or incorrect wiring may cause a fire or failure.
● When disconnecting a communication cable or power cable from the module, do not pull the cable
part.
For the cable with connector, hold the connector part of the cable.
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.
● 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.

[Startup and Maintenance 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 module fixing screws.
Failure to do so may result in electric shock or cause the module to fail or malfunction.
Undertightening can cause drop of the screw, short circuit, or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
CAUTION
● Before performing online operations (especially, program modification, forced output, and operation
status change) for the running CPU module from the peripheral connected, read relevant manuals
carefully and ensure the safety.
Improper operations may damage machines or cause accidents.
● Do not disassemble or modify the modules.
Doing so may cause failure, malfunction, injury, or a fire.
● Use any radio communication device such as a cellular phone or PHS (Personal Handy-phone
System) more than 25cm (9.85 inches) away in all directions from the programmable controller.
Failure to do so may cause malfunction.
● Shut off the external power supply (all phases) used in the system before mounting or removing the
module.
Failure to do so may cause the module to fail or malfunction.
● After the first use of the product, do not mount/remove the module to/from the base unit more than
50 times (IEC 61131-2 compliant).
Exceeding the limit of 50 times may cause malfunction.
● Do not drop or apply shock to the battery to be installed in the module.
Doing so may damage the battery, causing the battery fluid to leak inside the battery.
If the battery is dropped or any shock is applied to it, dispose of it without using.
● 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.

[Startup and Maintenance Precautions]
WARNING
● Before performing online operations (especially, program modification, forced output, and operation
status change) for the running CPU module from the peripheral connected, read relevant manuals
carefully and ensure the safety.
Incorrect change or modification may cause system malfunction, damage to the machines, or
accidents.
● Do not write any data to the "system area" in the buffer memory of 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 these operations may cause malfunctions to the programmable controller system.
