•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, 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".

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.

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 Section 8.2.6 in

this manual.

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

•When changing data of a running programmable controller from a peripheral connected to the

CPU module or from an external device such as a personal computer connected to an intelligent

function module, configure an interlock circuit in the program to ensure that the entire system

will always operate safely.

For other controls to a running programmable controller (such as program modification or

operating status change), read relevant manuals carefully and ensure the safety before the

operation.

Especially, in the case of a control from an external device to a remote programmable controller,

immediate action cannot be taken for a problem on 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.

!WARNING

!CAUTION

A - 2 A - 2

[Design Precautions]

!WARNING

•Do not write any data to the "system area" of the buffer memory in each intelligent function

module.

Also, do not turn on any "use prohibited" signal that is output from the CPU module to the

intelligent function module.

Writing data to the "system area" or outputting a "use prohibited" signal may cause malfunction

of the programmable controller system.

•When setting auto refresh parameters, specify "Y" for the remote output RY refresh devices.

Specifying any other than "Y" (for example, M or L) will hold the previous device status in the

case of a CPU stop.

For how to stop a data link, refer to Section 8.3.8.

•Disconnection of a CC-Link dedicated cable may make the line condition unstable, causing

communication errors on multiple stations on the network.

Configure an interlock circuit in the program so that the system will operate safely even if these

communication errors occur on multiple stations.

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

[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.

[Installation Precautions]

!WARNING

•Shut off the external power supply for the system in all phases before mounting or removing the

module.

Failure to do so may result in electric shock or cause the module to fail or malfunction.

A - 3 A - 3

[Installation Precautions]

!CAUTION

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

in "Safety Guidelines", the manual supplied with the CPU module or head module.

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

the product.

•To interconnect modules, engage the respective connectors and securely lock the module joint

levers.

Incorrect interconnection may cause malfunction, failure, and drop of the module.

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

Doing so can cause malfunction or failure of the module.

[Wiring Precautions]

!WARNING

•Shut off the external power supply for the system in all phases before 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 product before turning it on

for operation.

Failure to do so may result in electric shock.

[Wiring Precautions]

!CAUTION

•Use applicable solderless terminals and tighten them within the specified torque range.

If any spade solderless terminal is used, it may be disconnected when a screw on the terminal

block comes loose, resulting in failure.

•Do not install the control lines or communication cables together with the main circuit lines or

power cables.

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.

•Tighten the terminal block screw within the specified torque range.

Undertightening can cause 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 block screws.

Pulling the cable connected to the module may result in malfunction and damage to the module

or cable.

A - 4 A - 4

[Wiring Precautions]

!CAUTION

•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.

•For the CC-Link system, use dedicated cables that are specified by the manufacturer.

If any other cable is used, performance of the CC-Link system is not guaranteed.

Also, the maximum overall cable length and the station-to-station cable length must meet those

specified in Chapter 3.

If not, normal data communication 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.

•Shut off the external power supply for the system in all phases before cleaning the module or

retightening the screws on the terminal block.

Failure to do so may result in electric shock.

[Startup and Maintenance Precautions]

!CAUTION

•Do not disassemble or modify the modules.

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

•Shut off the external power supply for the system in all phases before connecting or

disconnecting the module.

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

•Tighten the screws on the terminal block within the specified torque range.

Undertightening can cause drop of parts or wires, 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 module, the number of module connections/disconnections is limited to

50 times.

Exceeding the limit (in accordance with IEC 61131-2) 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.
