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 instructions given in this manual are concerned with this product. For the
safety instructions of the programmable controller system, please read the User’s
Manual for the CPU module.
In this manual, the safety instructions are ranked as "DANGER" and "CAUTION".
Indicates that incorrect handling may cause
DANGER
CAUTION
Note that the CAUTION level may lead to a serious consequence according
to the circumstances.
Always follow the instructions of both levels because they are important to
personal safety.
Please save this manual to make it accessible when required and always forward

hazardous conditions, resulting in death or severe
injury.
Indicates that incorrect handling may cause
hazardous conditions, resulting in medium or slight
personal injury or physical damage.
[Design Precautions]
CAUTION
Do not bunch the control wires or pulse input lines with the main circuit or
power wires, or install them close to each other.They should be installed 150
mm (5.91 inch) or more from each other.Not doing so could result in noise
that would cause erroneous operation.
A-1
[Installation Precautions]
CAUTION
Use the programmable controller in the environment conditions given in the
general specifications of the User's Manual for the CPU module.
Using this programmable controller in an environment outside the range of
the general specifications could result in electric shock, fire, erroneous
operation, and damage to or deterioration of the product.
While pressing the installation lever located at the bottom of module, insert
the module fixing tab into the fixing hole in the base unit until it stops. Then,
securely mount the module with the fixing hole as a supporting point.
Incorrect loading of the module can cause a malfunction, failure or drop.
When using the programmable controller in the environment of much
vibration, tighten the module with a screw.
Tighten the screw in the specified torque range.
Undertightening can cause a drop, short circuit or malfunction.
Overtightening can cause a drop, short circuit or malfunction due to damage
to the screw or module.
Completely turn off the externally supplied power used in the system before
mounting or removing the module.
Not completely turning off all power could result in electric shock or damage
to the product.
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.
A-2
[Wiring Precautions]
CAUTION
When wiring/connecting the connector, properly press, crimp or solder the
connector using the tools specified by the manufactures and attach the
connector to the module securely.
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.
The module has an ingress prevention label on its top to prevent foreign
matter, such as wire offcuts, from entering the module during wiring.
Do not peel this label during wiring.
Before starting system operation, be sure to peel this label because of heat
dissipation.
Be sure to place the cables connected to the module in a duct or clamp them.
If not, dangling cables may swing or inadvertently be pulled, resulting in
damage to the module and/or cables, or malfunctions due to poor cable
connection.
When disconnecting the cable, do not pull it by holding the cable part.
Disconnect the cable with connector with holding the connector plugged into
the module. Pulling the cable part with the cable still connected to the module
may cause a malfunction or damage to the module and/or cable.
Always ground the shielded cable on the encoder side (relay box). Failure to
do may cause a malfunction.
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 voltage different from the rated voltage or incorrect wiring may
result in a fire or failure.
