[DESIGN PRECAUTIONS]
WARNING
●Make sure to set up the following safety circuits outside the PLC to ensure safe system operation
even during external power supply problems or PLC failure. Otherwise, malfunctions may cause
serious accidents.
- Most importantly, set up the following: an emergency stop circuit, a protection circuit, an interlock
circuit for opposite movements (such as normal vs. reverse rotation), and an interlock circuit (to
prevent damage to the equipment at the upper and lower positioning limits).
- Note that when the CPU module detects an error, such as a watchdog timer error, during self-
diagnosis, all outputs are turned off. Also, when an error that cannot be detected by the CPU
module occurs in an input/output control block, output control may be disabled. External circuits
and mechanisms should be designed to ensure safe machinery operation in such a case.
- Note that when an error occurs in a relay, transistor or triac of an output circuit, the output might
stay on or off. For output signals that may lead to serious accidents, external circuits and
mechanisms should be designed to ensure safe machinery operation in such a case.
●In an output circuit, when a load current exceeding the current rating or an overcurrent caused by a
load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an
external safety circuit, such as a fuse.
●For the operating status of each station after a communication failure of the network, refer to relevant
manuals for the network. Incorrect output or malfunction may result in an accident.
●Construct an interlock circuit in the program so that the whole system always operates on the safe
side before executing the control (for data change) of the PLC in operation.
Read the manual thoroughly and ensure complete safety before executing other controls (for program
change, parameter change, forcible output and operation status change) of the PLC in operation.
Otherwise, the machine may be damaged and accidents may occur due to erroneous operations.
●Especially, in the case of a control from an external device to a remote programmable controller,
immediate action cannot be taken for a problem on the programmable controller due to a
communication failure. Determine the handling method as a system when communication failure
occurs along with configuration of interlock circuit on a program, by considering the external
equipment and CPU module.
●Do not write any data to the "system area" and "write-protect area" of the buffer memory in the
intelligent function module. Executing data writing to the "system area" or "write-protect area" may
cause malfunction of the programmable controller alarm. For the "system area" or "write-protect
area", refer to Page 136 Buffer Memory.
●If a communication cable is disconnected, the network may be unstable, resulting in a communication
failure of multiple stations. Construct an interlock circuit in the program so that the system always
operates on the safe side even if communications fail. Incorrect output or malfunction may result in an
accident.

[DESIGN PRECAUTIONS]
[SECURITY PRECAUTIONS]
[INSTALLATION 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.
●When an inductive load such as a lamp, heater, or solenoid valve is controlled, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on. Take
proper measures so that the flowing current does not exceed the value corresponding to the
maximum load specification of the resistance load.
●Do not power off the CPU module or reset the CPU module while the settings are being written. Doing
so will make the data in the flash ROM undefined. The values need to be set in the buffer memory and
written to the flash ROM again. Doing so also may cause malfunction or failure of the module.
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 unreliable networks and devices via network, take appropriate measures such as
firewalls, virtual private networks (VPNs), and antivirus solutions.
WARNING
●Make sure to cut off all phases of the power supply externally before attempting installation or wiring
work. Failure to do so may cause electric shock or damage to the product.
●Use the product within the generic environment specifications described in the User's Manual
(Hardware) of the CPU module used.

[WIRING PRECAUTIONS]
[STARTUP AND MAINTENANCE PRECAUTIONS]
CAUTION
●Perform class D grounding (grounding resistance: 100or less) of the grounding terminal on the CPU
module and extension modules with a wire 2 mm2or thicker. Do not use common grounding with
heavy electrical systems (refer to the User's Manual (Hardware) of the CPU module used).
●Individually ground the FG terminal of the programmable controller with a ground resistance of 100
or less. Failure to do so may result in electric shock or malfunction.
●Install module so that excessive force will not be applied to terminal blocks, or communication cables.
Failure to do so may result in wire damage/breakage or PLC failure.
●Make sure to observe the following precautions in order to prevent any damage to the machinery or
accidents due to malfunction of the PLC caused by abnormal data written to the PLC due to the
effects of noise.
- Do not bundle the control line and communication cables together with or lay them close to the
main circuit, high-voltage line, load line or power line. As a guideline, lay the power line, control
line and communication cables at least 100mm away from the main circuit, high-voltage line, load
line or power line.
- Ground the shield of the shielded wire or shielded cable at one point on the PLC. However, do not
use common grounding with heavy electrical systems.
●For Ethernet cables to be used in the system, select the ones that meet the specifications described in
Page 67 Wiring Products. If not, normal data transmission is not guaranteed.
WARNING
●Do not touch any terminal while the PLC's power is on. Doing so may cause electric shock or
malfunctions.
●Before cleaning or retightening terminals, cut off all phases of the power supply externally. Failure to
do so in the power-on status may cause electric shock.
●Before modifying the program in operation, forcible output, running or stopping the PLC, read through
this manual carefully, and ensure complete safety. An operation error may damage the machinery or
cause accidents.
●Do not change the program in the PLC from two or more peripheral equipment devices at the same
time. (i.e. from an engineering tool and a GOT) Doing so may cause destruction or malfunction of the
PLC program.

[STARTUP AND MAINTENANCE PRECAUTIONS]
[OPERATION PRECAUTIONS]
CAUTION
●When connecting an external device with a CPU module or intelligent function module to modify data
of a running programmable controller, configure an interlock circuit in the program to ensure that the
entire system will always operate safely. For other forms of control (such as program modification,
parameter change, forced output, or operating status change) of a running programmable controller,
read the relevant manuals carefully and ensure that the operation is safe before proceeding. Improper
operation may damage machines or cause accidents.
●Especially, when a remote programmable controller is controlled by an external device, immediate
action cannot be taken if a problem occurs in the programmable controller due to a communication
failure. To prevent this, configure an interlock circuit in the program, and determine corrective actions
to be taken between the external device and CPU module in case of a communication failure.
●Do not disassemble or modify the PLC. Doing so may cause fire, equipment failures, or malfunctions.
For repair, contact your local Mitsubishi Electric representative.
●Turn off the power to the PLC before attaching or detaching the following devices. Failure to do so
may cause equipment failures or malfunctions.
- Peripherals, expansion board, expansion adapter, and connector conversion adapter
- Extension modules, bus conversion module, and connector conversion module
-Battery
●Read relevant manuals carefully and ensure the safety before performing online operations (operation
status change) with peripheral devices connected to the CPU modules of other stations. Improper
operation may damage machines or cause accidents.
CAUTION
●Construct an interlock circuit in the program so that the whole system always operates on the safe
side before executing the control (for data change) of the PLC in operation. Read the manual
thoroughly and ensure complete safety before executing other controls (for program change,
parameter change, forcible output and operation status change) of the PLC in operation. Otherwise,
the machine may be damaged and accidents may occur by erroneous operations.
●Do not power off the CPU module or reset the CPU module while the setting values in the buffer
memory are being written to the flash ROM in the intelligent function module. Doing so will make the
data in the flash ROM card undefined. The values need to be set in the buffer memory and written to
the flash ROM again. Doing so can cause malfunction or failure of the module.
●Note that the whole system may not be reset by the RUN/STOP/RESET switch when the CPU module
or intelligent function module detects an error, such as a watchdog timer error, during self-diagnosis.
In such cases, turn the power off and on again.
