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".
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
●When the safety remote I/O module detects an error in an external power supply or a failure in the
module, it turns off the outputs. Configure an external circuit to ensure that the power source of a
hazard is shut off by turning off the outputs. Failure to do so may result in an accident due to an
incorrect output or malfunction.
●When a load current exceeding the rated current or an overcurrent caused by a load short-circuit
flows, the safety remote I/O module defines it as a fault and turns off the outputs. Note that if the
overcurrent state continues for a long time, it may cause smoke and fire. To prevent this, configure an
external safety circuit, such as a fuse.
●At the start-up of the system, if the load power supply is short-circuited by the output wiring of the
safety remote I/O module, a load may turn on just after the power-on. Configure an interlock circuit to
ensure that the entire system will always operate safely.
●When a communication failure occurs in the network, data in the master module are held. Check Data
link status (each station) (SW00B0 to SW00B7) and configure an interlock circuit in the program to
ensure that the entire system will operate safely.
●When a communication failure occurs in the network, the failed station becomes the following status.
Check the communication status information and configure an interlock circuit in the program to
ensure that the entire system will operate safely. Failure to do so may result in an accident due to an
incorrect output or malfunction.
(1) All inputs from remote I/O stations are turned off.
(2) All outputs from remote I/O stations are turned off.
●Do not use any "use prohibited" signals as a safety remote I/O signal and a remote control/monitor
signal since they are used by the system. If any of the "use prohibited" signals are used (turned on or
off), the correct operation of the module cannot be guaranteed.
●Do not read/write data from/to the remote register since all areas of the remote register are "use
prohibited" areas. If data is read or written from/to the remote register, correct operation of the module
cannot be guaranteed.
WARNING Indicates that incorrect handling may cause hazardous conditions, resulting in
death or severe injury.
CAUTION Indicates that incorrect handling may cause hazardous conditions, resulting in
minor or moderate injury or property damage.

[Design Precautions]
[Installation Precautions]
[Installation Precautions]
[Wiring Precautions]
CAUTION
●Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction
due to noise.
●Select the external devices to be connected to the module by referring to the performance
specifications in this manual and considering the maximum inrush current. Connecting a device
exceeding the maximum inrush current may cause malfunction or failure of the module.
●During control of an inductive load such as a lamp, heater, or solenoid valve, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on.
Therefore, use a module that has a sufficient current rating.
WARNING
●Shut off the load power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may result in electric shock or cause the module to fail or malfunction.
CAUTION
●Use the module in an environment that meets the general specifications in this manual. Failure to do
so may result in electric shock, fire, malfunction, or damage to or deterioration of the product.
●Do not directly touch any conductive parts and electronic components of the module. Doing so can
cause malfunction or failure of the module.
●Securely fix the module with mounting screws. Failure to do so may cause the module to fail due to
increasing effects of vibrations.
●Securely connect the cable connectors. Poor contact may cause malfunction.
●After the first use of the product, do not connect/remove the connectors more than 50 times (IEC
61131-2/JIS B 3502 compliant). Exceeding the limit may cause malfunction.
WARNING
●Shut off the load power supply (all phases) used in the system before wiring. Failure to do so may
result in electric shock or cause the module to fail or malfunction.

[Wiring Precautions]
[Startup and Maintenance Precautions]
CAUTION
●Individually ground the FG metal fitting of the programmable controller with a ground resistance of 100
ohms or less. Failure to do so may result in electric shock or malfunction.
●Check the rated voltage and terminal layout before wiring to the module, and connect the cables
correctly. Connecting a power supply with a different voltage rating or incorrect wiring may cause a fire
or failure.
●Tighten the waterproof caps within the specified torque range. Undertightening can cause short
circuit, fire, or malfunction. Overtightening can damage the waterproof cap, resulting in short circuit or
malfunction.
●The module meets IP67 only when all of the waterproof plugs and waterproof caps are attached and
the cover of the station number setting switch is securely fixed with a screw.
●Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can
cause a fire, failure, or malfunction.
●Place the cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled,
resulting in damage to the module or cables or malfunction due to poor contact.
●Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction
due to noise.
●When disconnecting the cable from the module, do not pull the cable by the cable part. For the cable
with connector, hold the connector part of the cable. Pulling the cable connected to the module may
result in malfunction or damage to the module or cable.
●When an overcurrent caused by an error of an external device or a failure of the programmable
controller flows for a long time, it may cause smoke and fire. To prevent this, configure an external
safety circuit, such as a fuse.
●Wiring and replacement of a module must be performed by qualified maintenance personnel with
knowledge of protection against electric shock. For wiring methods, refer to "INSTALLATION AND
WIRING" in this manual.
WARNING
●Do not touch any connector while power is on. Doing so will cause electric shock or malfunction.
