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".
Items marked with an exclamation point in a triangle could also cause severe consequences,
depending on the circumstances, if not handled properly.
They indicate information that should be taken seriously and observed conscientiously.
Manuals supplied with the products should be stored carefully where they can be accessed whenever
necessary, and should always be passed on to the end user along with the equipment.
[Design Precautions]
WARNING
When a communication error occurs in data link, the faulty station will result in the following status.
Using the communication status information, configure up an interlock circuit in the sequence
program to make the system safe.
Misoutput or misoperation may cause an accident.
(1) General-purpose inputs from this module all switch off.
(2) General-purpose outputs from this module all switch off.
Some module failures may keep input/output on or off. Provide an external monitoring circuit for
I/O signals which may lead to serious accidents.
CAUTION
Do not bundle control lines or communication cables with main circuit or power lines or lay them
near these lines.
As a guideline, separate the cables at least 100mm(3.94inch).
Not doing so could result in noise that would cause erroneous operation.

A - 2
[Installation Precautions]
CAUTION
Use the module in an environment that conforms to the general specifications in the manual.
Otherwise, an electric shock, fire, misoperation or product damage or deterioration can occur.
Securely fix the module using the DIN rail or mounting screws and fully tighten the mounting
screws within the specified torque range.
Undertightening can cause a drop or misoperation.
Overtightening can cause a drop or misoperation due to damaged screws or module.
Do not touch the conductive areas of the module directly.
Otherwise, the module can misoperate or fail.
[Wiring Precautions]
WARNING
Before starting mounting, wiring or other work, always switch power off externally in all phases.
Otherwise, an electric shock, product damage or misoperation may occur.
When switching power on or starting operation after mounting, wiring or other work, always
install the supplied terminal cover to the product.
Otherwise, you may get an electric shock.
CAUTION
Be sure to shut off all phases of the external power supply used by the system before
installation or wiring.
Not doing so can cause the product to be damaged or malfunction.
Ground the FG terminal to the protective ground conductor dedicated to the programmable
controller.
Failure to do so may result in electric shock or malfunction.
Use applicable solderless terminals and tighten them with the specified torque. If any solderless
spade terminal is used, it may be disconnected when the terminal screw comes loose, resulting
in failure.
Before wiring the module, confirm the rated voltage and terminal arrangement of the product.
A fire or failure can occur if the power supply connected is different from the rating or wiring is
incorrect.
Tighten the terminal screws within the specified torque range.
Undertightening can cause a short circuit or misoperation.
Overtightening can cause a short circuit or misoperation due to damaged screws or module.
Ensure that foreign matters such as chips and wire off-cuts do not enter the module.
They can cause a fire, failure or misoperation.

A - 3
[Wiring Precautions]
CAUTION
Always secure the wires or cables connected to the module, e.g. run them in conduits or clamp
them.
Otherwise, the module or cables can be damaged due to dangling, moved or accidentally pulled
cables or misoperation can occur due to improper cable connection.
Do not install the control lines or communication cables together with the main circuit lines or
power cables.
Failure to do so may result in malfunction due to noise.
Do not hold the cable part when unplugging the communication or power cable connected to the
module.
When the cable is fitted with a connector, hold the connector of the cable part connected to the
module.
When the cable is not fitted with a connector, loosen the screw in the cable part connected to
the module. If you pull the cable connected to the module, the module or cable can be damaged
or misoperation can occur due to improper cable connection.
[Starting and Maintenance Precautions]
WARNING
Do not touch the terminals while power is on.
This can cause misoperation.
Before starting cleaning or terminal screw retightening, always switch power off externally in all
phases.
Otherwise, a module failure or misoperation can occur.

A - 4
[Starting and Maintenance Precautions]
CAUTION
Do not touch the terminals while the power is on.
Doing so may cause malfunction.
Do not drop or apply strong shock to the module.
Failure to do so may damage the module.
Do not disassemble or modify the module.
This can cause a failure, misoperation, injury or fire.
The module case is made of resin. Do not drop it or give it hard impact.
This can damage the module.
Be sure to shut off all phases of the external power supply used by the system before mounting
or dismounting the module to or from the panel.
Not doing so can cause the module to fail or malfunction.
Do not install/remove the terminal block more than 50 times after the first use of the product.
(IEC 61131-2 compliant)
Before handling the module, always touch grounded metal, etc. to discharge static electricity
from the human body.
Failure to do so can cause the module to fail or malfunction.
The pulse/external input voltage setting pins must be set after switching power off externally in
all phases.
Otherwise, the module can fail or misoperate.
[Precautions Regarding Product Disposal ]
CAUTION
When disposing of the product, handle it as industrial waste.
