[Design Precautions]
[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 external power supply is short-circuited by the output wiring of the
safety remote I/O module, or if the external power supply is connected with a wrong polarity, 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, 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) Remote stations turn off all output from terminals.
(2) Remote stations suspend safety communications.
●Do not use any "use prohibited" signals as a remote input or output signal. These signals are reserved
for system use. Do not write any data to the "use prohibited" areas in the remote register. If any of the
"use prohibited" signals are used (turned on or off), or any data is written to the "use prohibited" areas,
the correct operation of the module cannot be guaranteed. For system areas, "use prohibited" areas,
and "use prohibited" signals, refer to "APPENDICES" in the CC-Link IE TSN Remote I/O Module
(With Safety Functions) User's Manual. For areas used for safety communications, they are protected
from being written by users, and thus safety communications failure caused by data writing does not
occur.
●When the fast logic interlock is disabled, it is customer's responsibility to build the interlock circuit
externally so that the entire system always operates safely. Be sure to connect an interlock
mechanism to the output of this I/O module.
●If the measure to prevent the restart cannot be taken, take other measures and ensure that operators
are safe and machine parts are not damaged even if a device has restarted with the fast logic interlock
disabled.
CAUTION
●Do not install the cables connected to external devices or the 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.

[Wiring Precautions]
WARNING
●To maintain the security (confidentiality, integrity, and availability) of the programmable controller and
the system against unauthorized access, denial-of-service (DoS) attacks, computer viruses, and other
cyberattacks from external devices via the network, take appropriate measures such as firewalls,
virtual private networks (VPNs), and antivirus solutions.
WARNING
●Shut off the external 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.
●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.
●Connect each connection cable to the connector securely. Poor contact may cause malfunction.
WARNING
●Shut off the external 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]
CAUTION
●Individually ground the FG terminal 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 fire
or failure.
●Tighten the terminal block mounting screws within the specified torque range. Undertightening can
cause short circuit, fire, or malfunction. Overtightening can damage the screw and/or module,
resulting in drop, short circuit, or malfunction.
●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 cables may swing or inadvertently be pulled,
resulting in malfunction or damage to modules or cables. In addition, the weight of the cables may put
stress on modules in an environment of strong vibrations and shocks.
●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. For the cable connected to the terminal block,
loosen the terminal block screw. Pulling the cable connected to the module may result in malfunction
or damage to the module or cable.
●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 an overcurrent caused by an error of an external device or a failure of the module flows for a
long time, it may cause smoke and fire. To prevent this, configure an external safety circuit, such as a
fuse.
●Mitsubishi programmable controllers must be installed in control panels. 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.
