[DESIGN PRECAUTIONS]
DANGER
zDepending on the malfunction of the external output transistor, there may be cases
where the output is ON or OFF status. Install external monitoring circuitry for output
signals that may lead to major accidents.
CAUTION
zDo 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 150 mm(5.9 inch) or more from each other.
Not doing so could result in noise that may cause malfunction.

[INSTALLATION PRECAUTIONS]
CAUTION
zUse the programmable controller in an environment that meets the general specifications
contained in the CPU user's manual 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.
zWhen installing the module, securely insert the module fixing tabs into the mounting
holes of the base module while pressing the installation lever located at the bottom of the
module downward.
Improper installation may result in malfunction, breakdown or dropping out of the module.
Securely fix the module with screws if it is subject to vibration during use.
zTighten the screws within the range of specified torque.
If the screws are loose, it may cause 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.
zCompletely turn off the externally supplied power used in the system before mounting or
removing the module.
Not doing so could result in damage to the product.
Not doing so may cause electric shock or damage to the module.
zDo not directly touch the conductive area or electronic components of the module.
Doing so may cause malfunction or failure in the module.
[WIRING PRECAUTIONS]
CAUTION
zPerform correct pressure-displacement, crimp-contact or soldering for connector wire
connections using the tools specified by the manufactures.
Attach connectors to the module securely.
zBe careful not to let foreign matters such as sawdust or wire chips get inside the module.
These may cause fires, failure or malfunction.
zThe top surface of the module is covered with protective film to prevent foreign objects
such as cable offcuts from entering the module when wiring.
DO not remove this film until the wiring is complete.
Before operating the system, be sure to remove the film to provide adequate heat
ventilation.
zBe sure to fix communication cables or power supply cables leading from the module by
placing them in the duct or clamping them.
Cables not placed in the duct or without clamping may hang or shift, allowing them to be
accidentally pulled, which may cause a module malfunction and cable damage.
zWhen removing the communication cable from the module, do not pull the cable. When
removing the cable with a connector, hold the connector on the side that is connected to
the module.
Pulling the cable that is still connected to the module may cause malfunction or damage
to the module or cable.
zAlways ground the shielded cable on the encoder side (relay box).
Otherwise, malfunction may occur.
zWhen wiring, be sure to verify the rated voltage of the product as well as the terminal
layout. Fire or failure may result if incorrect voltage is input or incorrect wiring is
performed.
zConnecting terminals with incorrect voltage may result in malfunction or mechanical
failure.

3. Installation
3.1 Handling Precautions
The following explains the precautionary notes on handling the module.
1) Do not drop or apply severe shock to the module case since it is made of
resin.
2) Do not remove the PCB of each module from its case. Doing so may
cause breakdowns.
3) Be careful not to let foreign particles such as wire chips get inside the
module.
These may cause fire, breakdowns and malfunctions.
4) The top surface of the module is covered with a protective film to prevent
foreign objects such as wire chips from entering the module when wiring.
Do not remove this film until the wiring is complete.
Before operating the system, be sure to remove the film to provide
adequate heat ventilation.
5) Tighten the module fixing screw within the following specified torque range.
If the screw is too loose, it may cause a drop, short circuit, or malfunction.
Excessive tightening may damage the screw and/or the module, resulting
in a drop, short circuit or malfunction.
Screw location Tightening torque range
Module fixing screws (M3 screws) *1 0.36 to 0.48 N⋅m
*1 The module can be easily fixed onto the base unit using the hook at the top
of the module.
However, it is recommended to secure the module with the module fixing
screw if the module is subject to significant vibration or shock.

6) To mount the module on the base unit, fully insert the module fixing latch
into the fixing hole in the base unit and press the module using the hole as
a fulcrum.
Improper installation may result in a malfunction or breakdown of the
module, or may cause the module to fall off.
