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.

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 Precaution]

WARNING

Do not write any data to the "system area" or "write-protect area" of the buffer memory areas in

the intelligent function module. Also, do not use any "prohibited to use" signals as an output

signal to an intelligent function module from the programmable controller CPU.

Doing so may cause malfunction of the programmable controller system.

CAUTION

Do not bunch the control wires or communication cables with the main circuit or power wires, or

install them close to each other.

They should be installed 100mm or more from each other.

Not doing so could result in noise that may cause malfunction.

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

[Installation Precautions]

CAUTION

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

contained in the user's manual of the CPU module to use.

Using this programmable controller in an environment outside the range of the general

specifications may cause electric shock, fire, malfunction, and damage to or deterioration of the

product.

While pressing the installation lever located at the bottom of module, insert the module fixing tab

into the fixing hole in the base unit until it stops. Then, securely mount the module with the fixing

hole as a supporting point.

For the Q66AD-DG, secure the module with fixing brackets after installation to the base unit.

When using the Q68AD-G in an environment where they are frequent vibrations, screw the module

to the base unit after installation.

Tighten the screws within the range of specified torque.

If the screws are loose, it may cause the module to fallout, short circuits, or malfunction.

If the screws are tightened too much, it may cause damage to the screw and/or the module,

resulting in fallout, short circuits or malfunction.

Be sure to shut off all phases of the external power supply used by the system before mounting or

removing the module.

Not doing so may cause damage to the module.

In the system where a CPU module supporting the online module change is used and on the

MELSECNET/H remote I/O stations, modules can be replaced online (during energizing).

However, there are some restrictions on replaceable modules and the replacement procedures

are predetermined for each module.

For details, refer to the chapter of the online module change in this manual.

Do not directly touch the conductive area or electronic components of the module.

Doing so may cause malfunction or failure in the module.

A- 3

[Wiring Precautions]

CAUTION

Individually ground the FG terminal of the programmable controller with a ground resistance of

100Ωor less.

Not doing so can cause an electric shock or malfunction.

When turning on the power and operating the module after wiring is 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.

Tighten the terminal screws within the range of specified torque.

If the terminal screws are loose, it may result in short circuits or malfunction.

If the terminal screws are tightened too much, it may cause damage to the screw and/or the

module, resulting in short circuits or malfunction.

Be careful not to let foreign matter such as sawdust or wire chips get inside the module.

They may cause fires, failure or malfunction.

The top surface of the module is covered with protective film to prevent foreign objects such as

cable offcuts from entering the module when wiring.

Do not remove this film until the wiring is complete.

Before operating the system, be sure to remove the film to provide adequate ventilation.

A- 4

[Starting and Maintenance Precautions]

[Disposal Precautions]

CAUTION

Do not disassemble or modify the modules.

Doing so could cause failure, malfunction injury or fire.

Be sure to shut off all phases of the external power supply used by the system before mounting or

removing the module.

Not doing so may cause failure or malfunction of the module.

In the system where a CPU module supporting the online module change is used and on the

MELSECNET/H remote I/O stations, modules can be replaced online (during energizing).

However, there are some restrictions on replaceable modules and the replacement procedures

are predetermined for each module.

For details, refer to the chapter of the online module change in this manual.

Do not install/remove the module to/from the base unit more than 50 times after the first use of the

product. (IEC 61131-2 compliant)

Failure to do so may cause malfunction.

Do not touch the connector while the power is on.

Doing so may cause malfunction.

Be sure to shut off all phases of the external power supply before cleaning or retightening the

terminal screws or module fixing screws.

Not doing so may cause failure or malfunction of the module.

If the screws are loose, it may cause the module to fallout, short circuits, or malfunction.

If the screws are tightened too much, it may cause damages to the screws and/or the module,

resulting in the module falling out, short circuits or malfunction.

Always make sure to touch the grounded metal to discharge the electricity charged in the body,

etc., before touching the module.

Failure to do so may cause a failure or malfunctions of the module.

CAUTION

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