SAFETY PRECAUTIONS
(Read these precautions before using this product.)
Before using this product, please read this manual and the relevant manuals introduced in 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. Refer to the user's manual of the
CPU module to use for a description of the programmable controller system safety precautions.
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
Install a safety circuit external to the programmable controller that keeps the entire system safe
even when there are problems with the external power supply or the programmable controller.
Otherwise, trouble could result from erroneous output or erroneous operation.
(1) The status of analog output changes depending on the setting of various functions that
control the analog output. Take sufficient caution when setting for those functions.
For details of analog output status, refer to Section 3.4.1 ”Combinations of various
functions”
(2) Normal output may not be obtained due to malfunctions of output elements or the internal
circuits.
So build an external monitoring circuit that will monitor any single outputs that could cause
serious trouble.
!CAUTION
Do not bunch the control wires or communication cables with the main circuit or power wires, or
install them close to each other.
They should be installed 100mm (3.94inch) or more from each other.
Not doing so could result in noise that would cause erroneous operation.
At power ON/OFF, voltage or current may instantaneously be output from the output terminal of
this module.
In such case, wait until the analog output becomes stable to start controlling the external device.
!WARNING
!CAUTION

A - 2 A - 2
[Installation Precautions]
!CAUTION
Use the programmable controller in an environment that meets the general specifications in the
detailed manual.
Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of
the product.
Securely fix the module with a DIN rail or CC-Link connector type metal installation fitting.
Not doing so can cause a drop or malfunction.
Do not directly touch any conductive part of the module.
Doing so can cause malfunction or failure of the module.
[Wiring Precautions]
!CAUTION
Shut off the external power supply for the system in all phases before wiring.
Failure to do so may result in damage to the product.
Individually ground the FG terminal of the programmable controller with a ground resistance of
100Ωor less.
Failure to do so may result in malfunction.
Check the rated voltage and pin 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.
Do not insert the one-touch connector plug for I/O of the one-touch connector type/connector
type compact remote I/O unit into the one-touch connector for analog I/O accidentally.
Doing so can cause the module to be damaged.
Prevent foreign matter such as dust or wire chips from entering the module.
Such foreign matter can cause a fire, failure, or malfunction.
Attach an unwired connector plug to an unused one-touch connector for power supply and FG.
Not doing so can cause a failure or 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.
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.
When disconnecting the cable from the module, do not pull the cable by the cable part.
Loosen the screws of connector before disconnecting the cable.
Failure to do so may result in damage to the module or cable or malfunction due to poor contact.
Smoke and fire may occur when an overcurrent flows intermittently for a long period of time. To
avoid this, configure a safety circuit, such as an external fuse, to protect the product.

A - 3 A - 3
[Starting and Maintenance Precautions]
!CAUTION
Do not touch any pin while power is on. Doing so will cause malfunction.
Shut off the external power supply for the system in all phases before cleaning the module.
Failure to do so may cause the module to fail or malfunction.
Do not disassemble or modify the modules.
Doing so may cause failure, malfunction, injury, or a fire.
Do not drop or apply strong shock to the module. Doing so may damage the module.
Shut off the external power supply for the system in all phases before mounting or removing the
module to or from the panel.
Failure to do so may cause the module to fail or malfunction.
After the first use of the product, do not mount/remove the terminal block to/from the module
more than 50 times. (IEC 61131-2 compliant)
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 Precautions]
!CAUTION
When disposing of this product, treat it as industrial waste.
