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, refer to the user's manual for the CPU module used.

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.

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.

Precautions for using the QJ51AW12AL

[Design Precautions]

[Installation Precautions]

WARNING

●An AnyWireASLINK system has no control function for ensuring safety.

●When connecting a peripheral with the CPU module or connecting 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.

●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 CPU module 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.

WARNING

●Shut off the external power supply (all phases) used in the system before mounting or removing the

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

[Installation Precautions]

[Wiring 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 interconnection 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.

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.

[Wiring Precautions]

CAUTION

●Individually ground the FG and LG terminals of the programmable controller with a ground resistance

of 100 ohms or less.

Failure to do so may result in electric shock or malfunction.

●Check the rated voltage and terminal layout before wiring to the module, and connect the cables

correctly.

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

failure.

●Tighten the terminal block screws 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.

●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.

●Do not apply the 24VDC power before wiring the entire AnyWireASLINK system. If the power is

applied before wiring, normal data transmission is not guaranteed.

●Connect a 24VDC external power supply to the device(s) in an AnyWireASLINK system.

●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.

●When disconnecting the cable from the module, do not pull the cable by the cable part.

For the cable connected to the terminal block, loosen the terminal screw.

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

cable.

[Startup and Maintenance Precautions]

[Disposal 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 (all phases) used in the system before cleaning the module or

retightening the terminal block screws.

Failure to do so may result in electric shock.

CAUTION

●Do not disassemble or modify the module.

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 a

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

●Tighten the terminal block screws within the specified torque range.

Undertightening can cause drop of the component or wire, 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 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 of 50 times 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.

CAUTION

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