[Design Precautions]
WARNING
●Configure safety circuits external to the programmable controller to ensure that the entire system
operates safely even when a fault occurs in the external power supply or the programmable
controller.
Failure to do so may result in an accident due to an incorrect output or malfunction.
(1) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting
operations (such as forward/reverse rotations or upper/lower limit positioning) must be
configured external to the programmable controller.
(2) When the programmable controller detects an abnormal condition, it stops the operation and
all outputs are:
• Turned off if the overcurrent or overvoltage protection of the power supply module is
activated.
• Held or turned off according to the parameter setting if the self-diagnostic function of the CPU
module detects an error such as a watchdog timer error.
(3) All outputs may be turned on if an error occurs in a part, such as an I/O control part, where the
CPU module cannot detect any error. To ensure safety operation in such a case, provide a
safety mechanism or a fail-safe circuit external to the programmable controller. For a fail-safe
circuit example, refer to "General Safety Requirements" in the MELSEC iQ-R Module
Configuration Manual.
(4) Outputs may remain on or off due to a failure of a component such as a relay and transistor in
an output circuit. Configure an external circuit for monitoring output signals that could cause a
serious accident.
●In an output circuit, when a load current exceeding the rated current 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.
●Configure a circuit so that the programmable controller is turned on first and then the external
power supply. If the external power supply is turned on first, an accident may occur due to an
incorrect output or malfunction.
●For the operating status of each station after a communication failure, refer to manuals relevant to
the network. Incorrect output or malfunction due to a communication failure may result in an
accident.
●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.

[Design Precautions]
WARNING
●Do not write any data to the "system area" and "write-protect area" of the buffer memory in the
module. Also, do not use any "use prohibited" signals as an output signal from the CPU module
to each module. Doing so may cause malfunction of the programmable controller system. For
the "system area", "write-protect area", and the "use prohibited" signals, refer to the user's
manual for the module used.
●If a communication cable is disconnected, the network may be unstable, resulting in a
communication failure of multiple stations. Configure an interlock circuit in the program to
ensure that the entire system will always operate safely even if communications fail. Failure to
do so may result in an accident due to an incorrect output or malfunction.
●To maintain the safety of the programmable controller system against unauthorized access from
external devices via the network, take appropriate measures. To maintain the safety against
unauthorized access via the Internet, take measures such as installing a firewall.
●Configure safety circuits external to the programmable controller to ensure that the entire
system operates safely even when a fault occurs in the external power supply or the
programmable controller. Failure to do so may result in an accident due to an incorrect output or
malfunction.
●If safety standards (ex., robot safety rules, etc.,) apply to the system using the module, servo
amplifier and servomotor, make sure that the safety standards are satisfied.
●Construct a safety circuit externally of the module or servo amplifier if the abnormal operation of
the module or servo amplifier differs from the safety directive operation in the system.
●Do not remove the SSCNETIII cable while turning on the control circuit power supply of
modules and servo amplifier. Do not see directly the light generated from SSCNETIII connector
of the module or servo amplifier and the end of SSCNETIII cable. When the light gets into eyes,
you may feel something wrong with eyes. (The light source of SSCNETIII complies with class1
defined in JISC6802 or IEC60825-1.)

[Design Precautions]
WARNING
●Do not install the control lines or communication cables together with the main circuit lines or
power cables. Keep a distance of 100 mm 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.
●After the CPU module is powered on or is reset, the time taken to enter the RUN status varies
depending on the system configuration, parameter settings, and/or program size. Design
circuits so that the entire system will always operate safely, regardless of the time.
●Do not power off the programmable controller or do not reset the CPU module during the setting
registration. Doing so will make the data in the flash ROM undefined. The data need to be set in
the buffer memory and to be written to the flash ROM again. Doing so may cause malfunction or
failure of the module.
●When changing the operating status of the CPU module from external devices (such as remote
RUN/STOP), select "Do Not Open by Program" for "Opening Method" in the module
parameters. If "Open by Program" is selected, an execution of remote STOP causes the
communication line to close. Consequently, the CPU module cannot reopen the communication
line, and external devices cannot execute the remote RUN.

[Installation Precautions]
WARNING
●Shut off the external power supply (all phases) used in the system before mounting or removing
the module. Failure to do so may result in electric shock or cause the module to fail or
malfunction.
[Installation Precautions]
CAUTION
●Use the programmable controller in an environment that meets the general specifications in the
manual "Safety Guidelines" included in the base unit. Failure to do so may result in electric
shock, fire, malfunction, or damage to or deterioration of the product.
●To mount a module, place the concave part(s) located at the bottom onto the guide(s) of the
base unit, and push in the module until the hook(s) located at the top snaps into place. Incorrect
mounting may cause malfunction, failure, or drop of the module.
●To mount a module with no module fixing hook, place the concave part(s) located at the bottom
onto the guide(s) of the base unit, push in the module, and fix it with screw(s).
●When using the programmable controller in an environment of frequent vibrations, fix the
module with a screw.
●Tighten the screws within the specified torque range. Undertightening can cause drop of the
screw, short circuit, or malfunction. Overtightening can damage the screw and/or module,
resulting in drop, short circuiA-5t, or malfunction.
●When using an extension cable, connect it to the extension cable connector of the base unit
securely. Check the connection for looseness. Poor contact may cause incorrect input or output.
●When using an SD memory card, fully insert it into the memory card slot. Check that it is
inserted completely. Poor contact may cause malfunction.
●Securely insert an extended SRAM cassette into the cassette connector of a CPU module. After
insertion, close the cassette cover and check that the cassette is inserted completely. Poor
contact may cause malfunction.
●Do not directly touch any conductive parts and electronic components of the module, SD
memory card, extended SRAM cassette, or connector. Doing so may cause malfunction or
failure of the module.

[Wiring Precautions]
CAUTION
●Individually ground the FG and LG terminals of the programmable controller with a ground
resistance of 100 ohm or less. Failure to do so may result in electric shock or malfunction.
●Use applicable solderless terminals and tighten them within the specified torque range. If any
spade solderless terminal is used, it may be disconnected when the terminal screw comes
loose, resulting in failure.
●Check the rated voltage and signal 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.
●Connectors for external devices or coaxial cables must be crimped or pressed with the tool
specified by the manufacturer, or must be correctly soldered. Incomplete connections may
cause short circuit, fire, or malfunction.
●Securely connect the connector to the module. Poor contact may cause malfunction.
●Do not install the control lines or communication cables together with the main circuit lines or
power cables. Keep a distance of 100 mm or more between them. Failure to do so may result in
malfunction due to noise.
●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
clamp the extension cables with the jacket stripped. Doing so may change the characteristics of
the cables, resulting in malfunction.
●Check the interface type and correctly connect the cable. Incorrect wiring (connecting the cable
to an incorrect interface) may cause failure of the module and external device.
●Tighten the terminal screws or connector screws within the specified torque range.
Undertightening can cause drop of the screw, short circuit, fire, or malfunction. Overtightening
can damage the screw and/or module, resulting in drop, short circuit, fire, or malfunction.
●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.
●Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter
can cause a fire, failure, or malfunction.
●A protective film is attached to the top of the module to prevent foreign matter, such as wire
chips, from entering the module during wiring. Do not remove the film during wiring. Remove it
for heat dissipation before system operation.
●Programmable controllers must be installed in control panels. Connect the main power supply
to the power supply module in the control panel through a relay terminal block. Wiring and
replacement of a power supply module must be performed by qualified maintenance personnel
with knowledge of protection against electric shock. For wiring, refer to the MELSEC iQ-R
Module Configuration Manual.
●For Ethernet cables to be used in the system, select the ones that meet the specifications in the
