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.

A- 3
[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.
