[Design Precautions]
[Design Precautions]
WARNING
●When a communication failure occurs in the network, data in the CPU module on the master station
are held. Check the data link status of each station stored in the special register (SD) and configure an
interlock circuit in the program to ensure that the entire system will operate safely.
●When the module is disconnected due to a communication failure in the network or the CPU module is
in the STOP state, all outputs are held or turned off according to the function setting switch setting.
Configure an interlock circuit in the program to ensure that the entire system will always operate
safely even in such a case. If not, an accident may occur due to an incorrect output or malfunction.
●Outputs may remain on or off due to a failure of the module. Configure an external circuit for
monitoring output signals that could cause a serious accident.
●Do not use any "use prohibited" signals as a remote I/O signal since they are used by the system. Do
not write any data to the "use prohibited" areas in the remote register. Doing so may result in an
accident due to an incorrect output or malfunction.
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.
●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 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.

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.
●Securely connect the cable connectors. 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.
●Tighten any unused terminal screws within the specified torque range. Undertightening can cause a
short circuit due to contact with a solderless terminal.
●Use applicable solderless terminals and tighten them within the specified torque range. If any spade
solderless terminal is used, it may be disconnected when a terminal block screw comes loose,
resulting in failure.
●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 terminal block 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, fire, 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 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. For the cable connected to the terminal block,
loosen the terminal screw. 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.
●Mitsubishi Electric 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.
