[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.

[Design Precautions]
WARNING
●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 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. Incorrect output or malfunction due to a
communication failure may result in an accident.
●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.

[Design 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.
●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 reset the CPU module while the setting values in the
buffer memory 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
●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.

5
[Installation Precautions]
[Wiring Precautions]
CAUTION
●Use the programmable controller in an environment that meets the general specifications in the Safety
Guidelines included with 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 interconnection
may cause malfunction, failure, or drop of the module.
●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 circuit, 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 malfunction.
●When using an SD memory card, fully insert it into the SD 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 the 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 can cause malfunction or failure of the
module.
WARNING
●Shut off the external power supply (all phases) used in the system before installation and wiring.
Failure to do so may result in electric shock or cause the module to fail or malfunction.
●After installation and wiring, attach a blank cover module (RG60) to each empty slot and an included
extension connector protective cover to the unused extension cable connector before powering on the
system for operation. Failure to do so may result in electric shock.

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 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 100mm 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
