• 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 to 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 operating status of each communication failure, refer to this manual. Incorrect output or

malfunction due to a communication failure may result in an accident.

• If a coaxial cable is disconnected, this may destabilize the line, and a network communication

error may occur in multiple stations. Provide an interlock circuit in the sequence program so that

the system will operate safely even if the above error occurs. Failure to do so may result in an

accident due to incorrect output or malfunction.

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

CPU module or from a personal computer connected to an intelligent function module or special

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

system will always operate safely.

For program modification and operating status change, read relevant manuals carefully and

ensure the safety before 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 sequence 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]

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]

CAUTION

• Use the programmable controller in the operating an environment that meets the general

specifications given 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

module, fully insert the module fixing projection(s) into the hole(s) in the base unit 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 a screw.

Tighten the screw 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 for the system in all phases before mounting or removing the

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

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

Doing so can cause malfunction or failure of the module.

A - 3 A - 3

[Wiring Precautions]

WARNING

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

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

CAUTION

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

100 or less.

Failure to do so may result in electric shock malfunction.

• Check the rated voltage and terminal layout before wiring to the terminal block for the external

power supply, and connect the cable correctly.

Connecting a cable to power supply with a different voltage rating or incorrect wiring may cause

a fire or failure.

• Tighten the terminal screw 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.

• Properly solder the parts of a soldering-type coaxial cable connector. Incomplete soldering may

result in malfunction.

• Crimp the parts of a crimping-type coaxial cable connector with proper force at a proper position.

Failure to do so may cause drop of the cable or malfunction.

• 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 this film during wiring.

Remove it for heat dissipation before system operation.

• Place the cables in a duct or clamp them.

Failure to do so may cause damage of the module or the cables due to accidental pull or

unintentional shifting of the cables, or malfunctions due to poor contact of the cable.

• 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 disconnecting the communication and power cables from the module, do not pull the

cable by the cable part. Loosen the screws of connector before disconnecting the cable. When

disconnecting a cable connected to a terminal block, loosen the screws on the terminal block

first before removing the cable.

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

A - 4 A - 4

[Setup and Maintenance Precautions]

CAUTION

• Before performing online operations (especially, program modification, forced output, and

operation status change) for the running CPU module in other station from GX Developer via

MELSECNET/H, read relevant manuals carefully and ensure the safety.

• Do not disassemble or modify the module. Doing so may cause failure, malfunction, injury, or a

fire.

• Use any radio communication device such as a cellular phone or a PHS (Personal Handy-phone

System) more than 25cm (9.85 inches) away in all directions from the programmable controller.

Failure to do so may cause malfunction.

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

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

• Do not touch any terminals while power is on. Doing so will cause electric shock.

• Shut external power supply for 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.

• After the firs use of the product, do not mount/remove the module to/from the base unit more

than 50 times (IEC 61131-2 compliant) respectively.

Exceeding the limit of 50 times may cause malfunction.

• Before handling the module, touch a grounded metal object to discharge the static electricity

from the human body.

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