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 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 to use.

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 operation status of each station at communication error in each station, refer to the

respective manual for each station.

The communication error may result in an accident due to incorrect output or malfunction.

When using the notification function, the pager receiver may not be contacted due to the frequency

transmission status from the system setup environment and error on the receiver side.

To ensure the safety of the programmable controller system, install a call circuit with a lamp

display or buzzer sound.

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 program, and determine corrective actions to

be taken between the external device and CPU module in case of a communication failure.

A-2 A-2

[Design Precautions]

WARNING

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.

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.

When using the module while values, such as buffer memory set values, are registered in the

Flash ROM, do not turn off the power supply for the module loading station nor reset the

programmable controller CPU.

If the power supply for the module loading station is turned off or the programmable controller

CPU is reset while any values are registered, the data contents in the Flash ROM become

inconsistent and as a result the values must be set again in the buffer memory, etc. and

reregistered to the Flash ROM.

Also, this may cause failure and malfunction of the module.

[Installation Precautions]

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 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 A-3

[Wiring Precautions]

CAUTION

When turning on the power and operating the module after installation and wiring are completed,

always attach the terminal cover that comes with the product.

There is a risk of electric shock if the terminal cover is not attached.

Perform correct pressure-displacement, crimp-contact or soldering for external wire connections

using the tools specified by the manufactures.

Incorrect connection may cause short circuits, fire, or malfunction.

Attach connectors to the module securely.

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.

Before connecting the cables, check the type o f interface to be connected.

Connecting or erroneous wiring to the wrong interface may cause failure to the module and

external devices.

Tighten the terminal screws within the specified torque range.

Undertightening the terminal screws can cause 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.

Pulling the cable that is still connected to the module may cause 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.

A-4 A-4

[Startup/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 (all phases) used in the system before mounting or removing

the 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 may cause malfunction.

Do not touch any terminal while power is on.

Doing so may cause malfunction.

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.

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.

[Operation Precautions]

CAUTION

When changing data and operating status, and modifying program of the running programmable

controller from an external device such as a personal computer connected to an intelligent

function module, read relevant manuals carefully and ensure the safety before operation.

Failure to perform correct operations to change data, program, or the status may result in

system malfunction, machine damage, or an accident.

[Disposal Precautions]

CAUTION

When disposing of this product, treat it as industrial waste.
