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 this manual are concerned with this product. Refer to the User’s
Manual of the CPU module in use for details on the safety precautions for the
programmable controller system.
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 3.4.5 "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.
WARNING
CAUTION

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.
[Installation Precautions]
CAUTION
Use the programmable controller in an environment that meets the general
specifications in this manual. Failure to do so may result in electric shock, fire,
malfunction, or damage to or deterioration of the product.
For protection of the switches, do not remove the cushioning material before
installation.
Securely fix the module with a DIN rail or mounting screws. 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 the module's conductive parts or electronic components.
Touching the conductive parts could cause an operation failure or give damage to the
module.
[Wiring Precautions]
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.
Be sure to ground the FG terminals to the protective ground conductor. Not doing so
could result in erroneous operation.
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.
When wiring in the programmable controller, be sure that it is done correctly by
checking the product's rated voltage and the terminal layout.
Connecting a power supply that is different from the rating or incorrectly wiring the
product could result in fire or damage.

[Wiring Precautions]
CAUTION
Tighten the terminal screws with the specified torque.
If the terminal screws are loose, it could result in short circuits, fire, or erroneous
operation.
Overtightening can damage the screw and/or module, resulting in drop, short circuit,
or malfunction.
Be sure there are no foreign substances such as sawdust or wiring debris inside the
module.
Such debris could cause fires, damage, or erroneous operation.
Do not install the control lines together with the communication cables, or bring them
close to each other. Failure to do so may cause malfunctions due to noise.
When connecting the communication and power supply cables to the module, always
run them in conduits or clamp them.
Not doing so can damage the module and cables due to loose, moved or accidentally
pulled cables or can cause a malfunction due to a cable connection fault.
When disconnecting the communication and power supply cables from the module,
do not hold and pull the cable part.
Disconnect the cables after loosening the screws in the portions connected to the
module.
Pulling the cables connected to the module can damage the module and cables or
can cause a malfunction due to a cable connection fault.
[Startup and Maintenance Precautions]
CAUTION
Do not touch the terminals while power is on. Doing so may cause malfunctioning.
Be sure to shut off all phases of the external power supply used by the system before
cleaning or retightening the terminal screws.
Not doing so can cause the module to fail or malfunction.
Do not disassemble or modify the modules.
Doing so could cause trouble, erroneous operation, injury, or fire.
Do not drop or apply strong shock to the module.
Doing so may 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 could result in damage to the product.
Do not install/remove the terminal block more than 50 times after the first use of the
product. (IEC 61131-2 compliant)
Before touching the module, always touch grounded metal, etc. to discharge static
electricity from human body.
Failure to do so can cause the module to fail or malfunction.
[Disposal Precautions]
CAUTION
When disposing of this product, treat it as industrial waste.
