 SAFETY PRECAUTIONS 
(Read these precautions before using this product.)
Before using this product, please read this manual carefully and pay full attention to safety to handle the
product correctly.
The precautions given in this manual 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".
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.
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.
[Design Precautions]
! WARNING
 Do not write any data to the "system area" and "write-protect area" of the buffer memory in the
intelligent function module.
Also, do not use any "use prohibited" signals as input or output signals from the intelligent
function module to the CPU module.
Doing so may cause malfunction of the programmable controller system.
 Due to failure of the output element or internal circuit, normal output may not be obtained
correctly. Configure an external circuit for monitoring output signals that could cause a serious
accident.
! 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.
 At power-on or power-off, a current may flow between output terminals momentarily.
In this case, start the control after analog outputs become stable.
! WARNING
! CAUTION

A - 2 A - 2
[Security Precautions]
! WARNING
 To maintain the security (confidentiality, integrity, and availability) of the programmable controller
and the system against unauthorized access, denial-of-service (DoS) attacks, computer viruses,
and other cyberattacks from external devices via the network, take appropriate measures such
as firewalls, virtual private networks (VPNs), and antivirus solutions.
[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.
 If the screws are tightened too much, it may cause damage to the screw and/or the module,
resulting in fallout, short circuits or malfunction.
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. A module can be replaced online (while
power is on) on any MELSECNET/H remote I/O station or in the system where a CPU module
supporting the online module change function is used.
Note that there are restrictions on the modules that can be replaced online, and each module
has its predetermined replacement procedure.
For details, refer to the relevant chapter in this manual.
 Do not directly touch any conductive parts and electronic components of the module.
Doing so can cause malfunction or failure of the module.

A - 3 A - 3
[Wiring Precautions]
! CAUTION
 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.
 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.
 When disconnecting the cable from the module, do not pull the cable by the cable part. 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.
 Individually ground the FG terminal and shielded cables of the programmable controller with a
ground resistance of 100 or less.
Failure to do so may result in electric shock or malfunction.
 After wiring, attach the included terminal cover to the module before turning it on for operation.
Failure to do so may result in electric shock.
 Use applicable solderless terminals and tighten them within the specified torque range.
If any spade solderless terminal is used, it may be disconnected when the terminal screw comes
loose, resulting in failure.
 Check the rated voltage and terminal layout before wiring to the module, and connect the cables
correctly.
Connecting a power supply with a different voltage rating or incorrect wiring may cause a fire or
failure.

A - 4 A - 4
[Startup and Maintenance Precautions]
! 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.
Failure to do so may cause the module to fail or malfunction.
A module can be replaced online (while power is on) on any MELSECNET/H remote I/O station
or in the system where a CPU module supporting the online module change function is used.
Note that there are restrictions on the modules that can be replaced online, and each module
has its predetermined replacement procedure.
For details, refer to the relevant chapter in this manual.
 After the first use of the product, do not mount/remove the module to/from the base unit, and the
terminal block to/from the module more than 50 times (IEC 61131-2 compliant) respectively.
Exceeding the limit of 50 times may cause malfunction.
 Do not touch any terminal while power is on.
Failure to do so may cause malfunction.
 Shut off the external power supply (all phases) used in the system before cleaning the module or
retightening the terminal screws or module fixing screws.
Failure to do so may 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.
 Before handling the module, touch a grounded metal object to discharge the static electricity
from the human body.
Failure to do so may cause the module to fail or malfunction.
[Disposal Precaution]
! CAUTION
 When disposing of the product, handle it as industrial waste.
