SAFETY PRECAUTIONS
(Always read these instructions before using this equipment.)
Before using the product, please read this manual, the relevant manuals introduced in this manual,
standard programmable controller manuals, and the safety standards carefully and pay full attention to
safety to handle the product correctly.
In this manual, the safety instructions are ranked as " WARNING" and " 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 it to the end user.
WARNING
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.

A- 2
[Design Precautions]
WARNING
When a safety programmable controller detects an error in an external power supply or a failure in
programmable controller main module, it turns off all the outputs.
Create an external circuit to securely stop the power of hazard by turning off the outputs.
Incorrect configuration may result in an accident.
Create short current protection for a safety relay, and a protection circuit such as a fuse, and
breaker, outside a safety programmable controller.
If load current more than the rating or overcurrent due to a short circuit in the load has flowed in the
CC-Link Safety remote I/O module, the module defines it as a fault and turns off all the outputs.
However, if overcurrent flows in the CC-Link Safety remote I/O module for a long time, it may cause
smoke or a fire. To prevent it, create a safety circuit such as a fuse outside the module.
When a safety remote I/O module has detected CC-Link Safety error, it turns off all the outputs.
Note that the outputs in a sequence program are not automatically turned off.
If CC-Link Safety error has been detected, create a sequence program that turns off the outputs in
the program.
If the CC-Link Safety is restored with the outputs on, it may suddenly operate and result in an
accident.
To inhibit restart without manual operation after safety functions was performed and outputs were
turned OFF, create an interlock program which uses a reset button for restart.

[Design Precautions]
[Installation Precautions]
[Wiring Precautions]
CAUTION
Do not bunch the wires of external devices or communication cables together with the main circuit or
power lines, or install them close to each other.
They should be installed 100 mm (3.94 inch) or more from each other.
Not doing so could result in noise that would cause malfunctions.
Select the external devices to be connected to the CC-Link Safety remote I/O module, considering
the maximum inrush current with reference to the CC-Link Safety System Remote I/O Module User's
Manual.
CAUTION
Use a safety programmable controller in the environment that meets the general specifications
described in the QSCPU User's Manual (Hardware Design, Maintenance and Inspection).
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.
Make sure to fix CC-Link Safety remote I/O module with a DIN rail or mounting screws and tighten
the screws with the specified torque.
If the screws are too loose, it may cause a drop of the screw or module.
Overtightening may cause a drop due to the damage of the screw or module.
Do not directly touch the module's conductive parts or electronic components.
Doing so may cause malfunctions or a failure.
WARNING
Be sure to shut off all phases of the external supply power used by the system before wiring.
Not completely turning off all power could result in electric shock or damage to the product.
When energizing or operating the module after installation or wiring, be sure to close the attached
terminal cover.
Not doing so may result in electric shock.

A- 4
[Wiring Precautions]
CAUTION
Individually ground the FG and LG terminals of the programmable controller with a ground
resistance of 100or less. Failure to so may result in electric shock or malfunction.
Wire the module correctly after confirming the rated voltage and terminal layout.
Connecting a power supply of a different rated voltage or incorrect wiring may cause a fire or failure.
Tighten a terminal block mounting screw, terminal screw, and module mounting screw within the
specified torque range.
If the terminal block mounting screw or terminal screw is too loose, it may cause a short circuit, fire,
or malfunctions.
If too tight, it may damage the screw and/or the module, resulting in a drop of the screw or module, a
short circuit or malfunctions.
If the module mounting screw is too loose, it may cause a drop of the screw or module.
Overtightening the screw may cause a drop due to the damage of the screw or module.
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.
Be sure there are no foreign substances such as sawdust or wiring debris inside the module.Such
debris could cause a fire, failure, or malfunctions.
Be sure to fix the communication cables or power cables by ducts or clamps when connecting them
to the module.
Failure to do so may cause damage of the module or cables due to a wobble, unintentional shifting,
or accidental pull of the cables, or malfunctions due to poor contact of the cable.
When removing the connected communication cables or power cables, do not pull the cable with
grasping the cable part.
Remove the cable connected to the terminal block after loosening the terminal block screws.
Pulling the cable connected to a module may result in malfunctions or damage of the module or
cable.

[Startup and Maintenance precautions]
[Disposal Precautions]
WARNING
Do not touch the terminals while power is on.
Doing so could result in electric shock.
Turn off all phases of the external supply power used in the system when cleaning the module or
retightening the terminal block mounting screws, terminal screws, or module mounting screws.
Not doing so could result in electric shock.
Tighten a terminal block mounting screw, terminal screw, and module mounting screw within the
specified torque range.
If the terminal block mounting screw or terminal screw is too loose, it may cause a short circuit, fire,
or malfunctions.
If too tight, it may damage the screw and/or the module, resulting in a drop of the screw or module, a
short circuit or malfunctions.
If the module mounting screw is too loose, it may cause a drop of the screw or module.
Overtightening the screw may cause a drop due to the damage of the screw or module.
CAUTION
Do not disassemble or modify the modules.
Doing so could cause a failure, malfunctions, injury, or fire.
If the product is repaired or remodeled by other than the specified FA centers or us, the warranty is
not covered.
Restrict the mounting/removal of a module, base unit, and terminal block up to 50 times
(IEC61131-2-compliant), after the first use of the product.
Failure to do so may cause the module to malfunction due to poor contact of connector.
Since the module case is made of resin, do not drop or apply any strong impact to the module.
Doing so may damage the module.
Completely turn off the externally supplied power used in the system before mounting or removing
the module to/from the panel.
Not doing so may result in a failure or malfunctions of the module.
CAUTION
When disposing of this product, treat it as industrial waste.
