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.
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".
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]
WARNING
●When connecting GX Works2 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.
●For the operating status of each station after a communication failure, refer to Page 140, Section
8.1.7 in this manual. Incorrect output or malfunction due to a communication failure may result in an
accident.
●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" signals as an output signal from the CPU module to the
intelligent function module.
Doing so may cause malfunction of the programmable controller system.
●To set a refresh device in the network parameter, select the device Y for the remote output (RY)
refresh device. If a device other than Y, such as M and L, is selected, the CPU module holds the
device status even after its status is changed to STOP.
●If a communication cable is disconnected, the network may be unstable, resulting in a
communication failure of multiple stations. Configure an interlock circuit in the program to ensure
that the entire system will always operate safely even if communications fail.
Failure to do so may result in an accident due to an incorrect output or malfunction.

[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 mounting or removing 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
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 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.
●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.

[Wiring Precautions]
[Startup and Maintenance 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
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.
●Use 1000BASE-T-compliant Ethernet cables for Ethernet connection. For the maximum station-to-
station distance and the overall cable distance, follow the specifications in this manual. If not, normal
data transmission is not guaranteed.
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 screw. Failure to do so may result in electric shock.

[Startup and Maintenance Precautions]
[Disposal Precautions]
CAUTION
●Before performing online operations (especially, program modification, forced output, and operating
status change) for the running CPU module on another station from GX Works2 over CC-Link IE
Field Network, read relevant manuals carefully and ensure the safety. Improper operation 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 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 a
module. Failure to do so may cause the module to fail or malfunction.
●Tighten the screw 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.
●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 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 disposing of this product, treat it as industrial waste.
