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".
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 manual and then keep the manual in a safe place for future
reference.
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]
[Design Precautions]
WARNING
●For the operating status of each station after a communication failure, refer to manuals relevant to the
network. Incorrect output or malfunction due to a communication failure may result in an accident.
●To prevent the malfunction of the programmable controller system due to harmful e-mails, take
preventive measures (such as antivirus measures) so that the mail server for this module does not
receive harmful e-mails.
●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.
●When connecting a peripheral with the CPU module or connecting an external device, such as 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 in the system area of the buffer memory in the intelligent function module. Also,
do not use any use prohibited signals as an output signal from the programmable controller CPU to
the intelligent function module. Doing so may cause malfunction of the programmable controller
system.
CAUTION
●Do not bundle the control wires and the communication cables with the main circuit and the power
wires, and do not install them close to each other. They should be installed at least 100 mm (3.94 in.)
away from each other. Failure to do so may generate noise that may cause malfunctions.
●When changing the operating status of the CPU module (such as remote RUN/STOP) from the
external device, select "Always wait for OPEN (Communication possible at STOP time)" for the "Initial
timing" setting in the network parameter. The communication line will be closed when "Do not wait for
OPEN (Communications impossible at STOP time)" is selected and the remote STOP is executed
from the external device. Consequently, the CPU module cannot reopen the communication line, and
the external device cannot execute the remote RUN.

[Installation Precautions]
[Wiring Instructions]
CAUTION
●Use the programmable controller in an environment that meets the general specifications in the user's
manual for the CPU module used. Using the programmable controller in any other operating
environments may cause electric shocks, fires or malfunctions, or may damage or degrade the
module.
●While pressing the installation lever located at the bottom of module, insert the module fixing tab into
the fixing hole in the base unit until it stops. Then, securely mount the module with the fixing hole as a
supporting point. If the module is not installed properly, it may cause the module to malfunction, fail or
fall off. Secure the module with screws especially when it is used in an environment where constant
vibrations may occur.
●Be sure to tighten the screws using the specified torque. If the screws loose, it may cause the module
to short-circuit, malfunction or fall off. If the screws are tightened excessively, it may damage the
screws and cause the module to short-circuit, malfunction or fall off.
●Shut off the external power supply (all phases) used in the system before mounting or removing the
module. Failure to do so may cause product damage.
●Do not directly touch any conductive part or electronic component of the module. This may cause the
module to malfunction or fail.
CAUTION
●Connectors for external devices and coaxial cables 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.
●Shut off the external power supply (all phases) used in the system before connecting the AUI cable.
●Securely connect the connector to the module. Poor contact may cause malfunction.
●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.
●Tighten the terminal screws using the specified torque. If the terminal screws are loose, it may cause
the module to short-circuit, malfunction or fall off. If the terminal screws are tightened excessively, it
may damage the screws and cause the module to short-circuit, malfunction or fall off.
●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.
●Be careful not to let any foreign matter such as wire chips get inside the module. They may cause fire,
as well as breakdowns and malfunctions of the module.
●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. 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. Remove it for heat
dissipation before system operation.

[Setup and Maintenance Precautions]
[Setup and Maintenance Precautions]
[Precautions When Disposing of This Product]
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 screws, connector screws, or module fixing screws. Failure to do so may
result in electric shock or cause the module to fail or malfunction.
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 mounting or removing the
module.
●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.
●Always make sure to touch the grounded metal to discharge the electricity charged in the body, etc.,
before touching the module. Failure to do so may cause a failure or malfunctions of the module.
CAUTION
●Dispose of this product as an industrial waste.
