SAFETY PRECAUTIONS

(Always read these instructions before using this product.)

Before using this product, please read this manual and the relevant manuals introduced in this manual

carefully and pay full attention to safety to handle the product correctly.

The instructions given in this manual are concerned with this product. For the safety instructions of the

programmable controller system, please read the user's manual of 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

For the operating status of each station after a communication failure, refer to relevant manuals for

each network.

Failure to do so may result in an accident due to an incorrect output or malfunction.

When connecting a peripheral with the CPU module or connecting an external device, such as a

personal computer, with an 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 or operating status change) of a running

programmable controller, read the relevant manuals carefully and ensure that the operation is safe

before proceeding.

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 sequence 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" of the buffer memory in the intelligent function module.

Also, do not use any "use prohibited" signals as an output signal from the programmable controller

CPU to the intelligent function module.

Doing so may cause malfunction of the programmable controller system.

WARNING

CAUTION

Indicates that incorrect handling may cause hazardous conditions,

resulting in death or severe injury.

Indicates that incorrect handling may cause hazardous conditions,

resulting in minor or moderate injury or property damage.

A- 2

[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.

CAUTION

Use the programmable controller in an environment that meets the general specifications in the

user's manual for the CPU module used.

Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the

product.

To mount the module, while pressing the module mounting lever located in the lower part of the

module, fully insert the module fixing projection(s) into the hole(s) in the base unit and press the

module until it snaps into place.

Incorrect mounting 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 terminal 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.

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

module. Failure to do so may result in damage to the product.

Do not directly touch any conductive parts and electronic components of the module.

Doing so can cause malfunction or failure of the module.

A- 3

[WIRING PRECAUTIONS]

]

WARNING

Shut off the external power supply (all phases) used in the system before wiring.

Failure to do so may result in electric shock or damage to the product.

After wiring, attach the included terminal cover to the module before turning it on for operation.

Failure to do so may result in electric shock.

CAUTION

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.

Check the rated voltage and terminal 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 a fire or

failure.

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.

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 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 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.

Failure to do so may result in damage to the module or cable or malfunction due to poor contact.

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.

A- 4

[STARTUP AND MAINTENANCE PRECAUTIONS]

[DISPOSAL PRECAUTIONS]

WARNING

Do not touch any terminal while power is on.

Doing so will cause electric shock.

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

retightening the terminal screws or module fixing screws.

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

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.

CAUTION

Before performing online operations (especially, program modification, forced output or operating

status change) by connecting a peripheral device to a running CPU, read the manual carefully and

ensure the safety.

Improper operation may damage machines or cause accidents.

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 a

module.

Failure to do so may cause the module to fail 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 more than 50 times (IEC 61131-2 compliant) respectively.

Exceeding the limit of 50 times may cause malfunction.

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.

CAUTION

When disposing of this product, treat is as an industrial waste.
