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 CPU module User's Manual.

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.

Make sure that the end users read this manual and then keep the manual in a safe place for future

reference.

[Design Precautions]

WARNING

Do not write data into the "read-only area" in the buffer memory of the intelligent function

module. In addition, do not turn on/off the "reserved" signals among the I/O signals transferred

to/from the programmable controller CPU.

Doing so can malfunction the programmable controller system.

Depending on the malfunction of the external output transistor, there may be cases where the

output is on or off status. Install external monitoring circuitry for output signals that may lead to

major accidents.

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 100 mm(3.94 inch) or more from each other.

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

[Installation Precautions]

CAUTION

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

contained in the CPU User's Manual.

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.

Improper installation may result in malfunction, breakdown or the module coming loose and

dropping. Securely fix the module with screws if it is subject to vibration during use.

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 ding so may cause electric shock or 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 A - 3

[Wiring Precautions]

CAUTION

Be careful not to let foreign matters 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 heat ventilation.

Be sure to fix communication cables or power supply cables leading from the module by placing

them in the duct or clamping them.

Cables not placed in the duct or without clamping may hang or shift, allowing them to be

accidentally pulled, which may cause a module malfunction and cable damage.

Do not grab on the cable when removing the communication or power cable connected to the

module.

When disconnecting a cable without a connector, first loosen the screws on the part that is

connected to the module.

Pulling the cable when it is still connected to the module may cause damage to the module or

cable, or misoperation due to cable contact failure.

Always ground the shielded cable for the programmable controller.

There is a risk of electric shock or malfunction.

Use applicable solderless terminals and tighten them with the specified torque. If any solderless

spade terminal is used, it may be disconnected when the terminal screw comes loose, resulting

in failure.

When wiring, be sure to verify the rated voltage of the product as well as the terminal layout. Fire

or failure may result if incorrect voltage is input or incorrect wiring is performed.

[Startup/Maintenance Precautions]

CAUTION

Do not disassemble or modify the module.

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, or the terminal block to/from the module

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.

Always shut off all phases of the external supply power used by the system before cleaning or

retightening screws/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.

[Disposal Precautions]

CAUTION

When disposing of the product, handle it as industrial waste.
