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".
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 data into the "System area" of the buffer memory of intelligent function modules.
Also, do not use any "Use prohibited" signals as an output signal to an intelligent function
module from the programmable controller CPU.
Writing data into the "System area" or outputting a signal for "Use prohibited" may cause a
programmable controller system malfunction.
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(3.9inch) or more from each other.
Not doing so could result in noise that may cause malfunction.
At power-on, a voltage may be applied or a current may flow between output terminals for a
moment. 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
contained in the user's manual of the CPU module to use.
Using this programmable controller in an environment outside the range of the general
specifications may cause electric shock, fire, malfunction, and damage to or deterioration of the
product.
While pressing the installation lever at the bottom of module, insert the module fixing tab into the
fixing hole in the base unit until it stops.
Improper installation may result in malfunction, breakdown or the module coming loose and
dropping.
Securely fix the module with screws if it is subject to vibration during use.
Tighten the screws within the range of specified torque.
If the screws are loose, it may cause the module to fallout, short circuits, or malfunction.
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.
Be sure to shut off all phases of the external power supply used by the system before mounting
or removing the module.
Not doing so may cause damage to the module.
In the system where a CPU module supporting Online module change is used and on the
MELSECNET/H remote I/O stations, modules can be replaced online (during energizing).
However, there are some restrictions on replaceable modules and the replacement procedures
are predetermined for each module.
For details, refer to the chapter of Online module change in this manual.
Do not directly touch the conductive area or electronic components of the module.
Doing so may cause malfunction or failure in the module.
[Wiring Precautions]
WARNING
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.
CAUTION
Individually ground the FG terminal of the programmable controller with a ground resistance of
100Ωor less.
There is a risk of 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.
Tighten the terminal screws within the specified torque range.
Undertightening can cause short circuit, fire, or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or
malfunction.

A-3 A-3
CAUTION
Be careful not to let foreign matter such as sawdust or wire chips get inside the module.
They may cause fires, 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.
[Starting and Maintenance Precautions]
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 terminal screws or module mounting 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.
CAUTION
Do not disassemble or modify the modules.
Doing so could cause failure, malfunction injury or fire.
Be sure to shut off all phases of the external power supply used by the system before mounting
or removing the module.
Not doing so may cause failure or malfunction of the module.
In the system where a CPU module supporting Online module change is used and on the
MELSECNET/H remote I/O stations, modules can be replaced online (during energizing).
However, there are some restrictions on replaceable modules and the replacement procedures
are predetermined for each module.
For details, refer to the chapter of Online module change in this manual.
Do not install/remove the module to/from the base unit, or the terminal block to/from the module
more than 50 times after the first use of the product. (IEC 61131-2 compliant)
Failure to do so may cause malfunction.
Always make sure to touch the grounded metal to discharge the electricity charged in the body,
etc., before touching the module.
Failure to do so may cause a failure or malfunctions of the module.
