SAFETY PRECAUTIONS

(Read these precautions before using this product.)

Before using this product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle

the product correctly.

The precautions given in this manual are concerned with this product only. For the safety precautions of the programmable

controller system, refer to the MELSEC iQ-R Module Configuration Manual.

In this manual, the safety precautions are classified into two levels: " WARNING" and " CAUTION".

Under some circumstances, failure to observe the precautions given under " CAUTION" may lead to serious

consequences.

Observe the precautions of both levels because they are important for personal and system safety.

Make sure that the end users read this manual and then keep the manual in a safe place for future reference.

[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.

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.

[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. 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.

●When a communication error occurs on the PROFIBUS-DP network, the operating status of each

station is as shown below ((1), (2), or (3)). Check the communication status information ('Diagnostic

information detection signal' (X1), 'Diagnostic information area (for mode 3)' (Un\G23072 to

Un\G23321), and 'Extended diagnostic information area (for mode 3)' (Un\G23328 to Un\G23454))

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) The DP-Master holds the input data before a communication error occurs.

(2) When the DP-Master has gone down, the output status of each DP-Slave is dependent on the

parameter setting.

(3) When a DP-Slave has gone down, the output status of other DP-Slaves is dependent on the

parameter setting of the DP-Master.

●When a stop error has occurred in the CPU module, the status of the RJ71PB91V is as shown below.

(1) When "Output Mode upon CPU Error" is set to "Clear".

• Data exchanges with DP-Slaves are interrupted.

• Output data in the buffer memory of the RJ71PB91V are cleared and are not transmitted.

• Input data received from DP-Slaves when a stop error has occurred in the CPU module are

held in the buffer memory of the RJ71PB91V.

(2) When "Output Mode upon CPU Error" is set to "Hold".

• Data exchanges with DP-Slaves are continued.

• Output data in the buffer memory of the RJ71PB91V are held the value when a stop error has

occurred in the CPU module and are transmitted to DP-Slaves.

• The buffer memory of the RJ71PB91V is updated by input data received from DP-Slaves.

[Design 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 settings are being

written. Doing so will make the data in the flash ROM and SD memory card undefined. The values

need to be set in the buffer memory and written to the flash ROM and SD memory card again. Doing

so also may cause malfunction or failure of the module.

●When changing the operating status of the CPU module from external devices (such as the remote

RUN/STOP functions), select "Do Not OPEN in Program" for "Open Method Setting" of "Module

Parameter". If "OPEN in Program" is selected, an execution of the remote STOP function causes the

communication line to close. Consequently, the CPU module cannot reopen the line, and external

devices cannot execute the remote RUN function.

[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.

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.

●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). 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.

[Wiring Precautions]

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.

CAUTION

●Individually ground the FG and LG terminals of the programmable controller with a ground resistance

of 100 ohms or less. Failure to do so may result in electric shock or malfunction.

●Use a solderless terminal with an insulation sleeve for terminal block wiring. Note that up to two

solderless terminals can be connected per terminal block.

●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 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.

●When an overcurrent caused by an error of an external device or a failure of a module flows for a long

time, it may cause smoke and fire. To prevent this, configure an external safety circuit, such as a fuse.

●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.

●When disconnecting the communication cable or power cable from the module, do not pull the cable

by the cable part. For the cable connected to the terminal block, loosen the terminal screws. Pulling

the cable connected to the module may result in malfunction or damage to the module or cable.

●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.

[Wiring Precautions]

CAUTION

●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.

●Tighten the terminal block mounting screws, terminal screws, and module fixing screws within each

specified torque range. Undertightening of the terminal block mounting screws and terminal screws

can cause short circuit, fire, or malfunction. Overtightening of them can damage the screw and/or

module, resulting in drop, short circuit, or malfunction. Undertightening of the module fixing screws

can cause drop of the screw. Overtightening of them can damage the screw and/or module, resulting

in drop.

●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 user's

manual for the module used. If not, normal data transmission is not guaranteed.

[Startup and Maintenance Precautions]

WARNING

●Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction.

●Correctly connect the battery connector. Do not charge, disassemble, heat, short-circuit, solder, or

throw the battery into the fire. Also, do not expose it to liquid or strong shock. Doing so will cause the

battery to produce heat, explode, ignite, or leak, resulting in injury and fire.

●Shut off the external power supply (all phases) used in the system before cleaning the module or

retightening the terminal screws, connector screws, or module fixing screws. Failure to do so may

result in electric shock.

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 modules. Doing so may cause failure, malfunction, injury, or a fire.

●Use any radio communication device such as a cellular phone or PHS (Personal Handy-phone

System) more than 25cm away in all directions from the programmable controller. Failure to do so

may cause malfunction.

●Shut off the external power supply (all phases) used in the system before mounting or removing the

module. Failure to do so may cause the module to fail or malfunction.

●Tighten the screws within the specified torque range. Undertightening can cause drop of the

component or wire, short circuit, or malfunction. Overtightening can damage the screw and/or module,

resulting in drop, short circuit, or malfunction.

●After the first use of the product, do not mount/remove the module to/from the base unit, and the

terminal block to/from the module, and do not insert/remove the extended SRAM cassette to/from the

CPU module more than 50 times (IEC 61131-2 compliant) respectively. Exceeding the limit may cause

malfunction.

●After the first use of the product, do not insert/remove the SD memory card to/from the CPU module

more than 500 times. Exceeding the limit may cause malfunction.

●Do not touch the metal terminals on the back side of the SD memory card. Doing so may cause

malfunction or failure of the module.

●Do not touch the integrated circuits on the circuit board of an extended SRAM cassette. Doing so may

cause malfunction or failure of the module.

●Do not drop or apply shock to the battery to be installed in the module. Doing so may damage the

battery, causing the battery fluid to leak inside the battery. If the battery is dropped or any shock is

applied to it, dispose of it without using.
