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.

(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 user's manual for the CPU module used.

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.

1

[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 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.

● 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" in the module
parameters. 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.

2

[Installation 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.

[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 the included terminal cover to the module before turning it on for
operation. Failure to do so may result in electric shock.

3

[Wiring Precautions]

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 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.

● 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.

● 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
MELSEC iQ-R Ethernet/CC-Link IE User's Manual (Startup). If not, normal data transmission is not
guaranteed.

● Use Ver.1.10-compatible CC-Link dedicated cables in a CC-Link system.
If not, the performance of the CC-Link system is not guaranteed.
For maximum overall cable length and station-to-station cable length, select the one that meet the
specifications in this manual. If not, n

ormal dat

a 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.

5

[Startup and Maintenance 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 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.

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

● 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.

● Startup and maintenance of a control panel must be performed by qualified maintenance personnel
with knowledge of protection against electric shock. Lock the control panel so that only qualified
maintenance personnel can operate it.

● Before handling the module, touch a conducting object such as a grounded metal to discharge the
static electricity from the human body. Failure to do so may cause the module to fail or malfunction.

5.1 CC-Link System Configuration

A CC-Link system is configured with a master station, remote I/O station, remote device station, intelligent device station, and

local station.

5

The CC-Link version and the number of slave stations that can be connected vary depending on the mode of the master/local
module. ( Page 19 Maximum Number of Connectable Modules)

Master/local modules of other series can be also used in a CC-Link system.

Remote station (internal 5VDC)

Input (Xn)

Turning off the input external power supply turns off an input (Xn)
after the response time between the input module turning on and
it turning off.

Please consider the following for system design to prevent incorrect input from a remote station.

When turning on and off the power

Power on the remote station, then start data link. In addition, stop data link before turning off the remote station. Failure to do

so may cause an incorrect input.

Upon a momentary power failure of a remote station

If a momentary power failure occurs in the power supply (24VDC) of the remote station, an incorrect input may occur.

■Cause of an incorrect input due to a momentary power failure

The hardware of a remote station internally converts the power supply of a module (24VDC) into 5VDC. If an instantaneous

power failure occurs at a remote station, (the time until the 5VDC power supply in the remote station turns off) > (the response
time after an input module turns on and off); therefore, refreshing data within the time as shown in  below causes an

incorrect input.

■Countermeasure against an incorrect input

Supply power to the power supply module, stabilized power supply, and AC input external power supply from the same power

supply.

5 SYSTEM CONFIGURATION

5.2 Precautions for the System Configuration

When supplying power to multiple remote stations from one power supply, select applicable cables and

properly wire them to prevent a voltage drop caused by the power supply. When a remote station has a

receiving end voltage within the specified range for the remote station used, it can be connected.

Access to a station with the station number 64

■Access from other stations using an engineering tool and GOT

Access to a local station with the station number 64 cannot be performed from other stations. Changing the station number to

the one other than 64 allows access from other stations.

■Access to other stations using a CC-Link system mater/local interface board

Access to a local station and intelligent device station with the station number 64 cannot be performed from other stations.

Changing the station number to the one other than 64 allows access from other stations.

Wiring to terminal block

Shows wiring to the terminal block.

• Connect the terminating resistors between the DA and DB terminals.

• Connect the shield wires of a Ver.1.10 compatible CC-Link dedicated cable to the SLD terminal through the

FG terminal. Then ground the cables at both ends with a ground resistance of 100 ohms or less. The SLD

and FG terminals are connected inside.

• For the terminal processing of when connecting the Ver.1.10-compatible CC-Link dedicated cable to the

terminal block, do not unfasten the DA/DB/DG cable (three wires in one cable) or remove the sheath more

than necessary. (For cables with fillers, cut them using a tool.)
