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 Precautions]

WARNING

When controlling (changing data, program or operation status (remote RUN/

STOP) in particular) a PLC while it is running via a device such as a personal

computer connected to the special function module, configure an interlock

circuit in the sequence program so that the safety of the overall system is

always maintained.

Especially, when performing the above control for a remote PLC from an

external device, troubles occurring on the PLC side due to data

communication error may not be handled immediately.

Determine error handling methods between the external device and the PLC

CPU for when data communication errors occur, in addition to configuring a

interlock circuit in the sequence program.

WARNING

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.

CAUTION

A-2

[Design Precautions]

[Installation Precautions]

CAUTION

When laying the control wire or communication cable, do not bundle with or

place near main circuit or power line.

Keep them at least 100 mm (3.94 in.) away from such cables.

Noise may cause erroneous operation.

CAUTION

Use the PLC in the environment given in the general specifications section of

the user's manual to be used. Using the PLC outside the range of the general

specifications may result in electric shock, fire, or erroneous operation or

may damage or degrade the product.

Make sure to switch all phases of the external power supply off when

installing or placing wiring. If you do not switch off the external power supply,

it will cause electric shock or damage to the product.

Make sure to switch all phases of the external power supply off before

mounting or removing the module. If you do not switch off the external power

supply, it may result in electric shock, or may damage the product.

Insert the fixing latch on the bottom of the module into the fixing hole in the

base unit and install the module using the hole point as a fulcrum. (The AnS

series module shall be fastened by screws in the base unit at the specified

torque.)

Not installing the module correctly could result in erroneous operation,

damage, or pieces of the product falling.

Tighten the screw within the range of specified torque.

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

Tightening the screws to far may cause damage to the screw and/or the

module, resulting in fallout, short circuits or malfunction.

Do not touch the electronic parts or the module conducting area directly.

It may cause erroneous operation or failure.

A-3

[Wiring Precautions]

CAUTION

Do not connect the AUI cable when the module installation station's power is

turned on.

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 connector to the module securely.

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, alllowing them to be

accidentally pulled, which may cause a module malfunction and cable

damage.

Tighten the screw within the range of specified torque.

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

Tightening the screws to far may cause damage to the screw and/or the

module, resulting in fallout, short circuits or malfunction.

Do not grab on the cable when removing the communication cable

connected to the module.

When removing the cable with a connector, hold the connector on the side

that is connected to the module.

When removing the cable connected to the terminal block, first loosen the

screws on the part that is connected to the terminal block.

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

malfunction or damage to the module or cable.

Solder coaxial cable connectors properly.

Insufficient soldering may cause malfunction.

Be sure that cuttings, wire chips, or other foreign matter do not enter the

module.

Foreign matter may start a fire or cause an accident or erroneous operation.

A-4

[Startup and Maintenance Precautions]

WARNING

Do not touch the terminals while the electricity is on.

Doing so could cause erroneous operation.

Make sure to switch all phases of the external power supply off before

cleaning or re-tightening screws.

If you do not switch off the external power supply, it will cause failure or

erroneous operation of the module.

If the screws are loose, it may result in fallout, short circuits, or erroneous

operation.

Tightening the screws too far may cause damage to the screws and/or the

module, resulting in fallout, short circuits, or erroneous operation.

CAUTION

Do not disassemble or rebuild the module.

It may cause failure, erroneous operation, injury, or fire.

Make sure to switch all phases of the external power supply off before

mounting or removing the module.

If you do not switch off the external power supply, it will cause failure or

erroneous operation of the module.

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.

A-5

[Operating Precautions]

[Disposal Precautions]

WARNING

Do not write data in the “system area” in the buffer memory of the special

function module.

Also, of the output signals directed to the special function module from the

PLC CPU, do not output (switch on) the signals that are “use-prohibited”.

If data is written to the ”system area” or output is performed with respect to a

“use-prohibited” signal, it may result in the malfunction of the PLC system.

CAUTION

Before performing the control of the PLC in operation (especially changing

data, program, and operation status (remote RUN/STOP)) by connecting a

personal computer, etc. to the special function module, read the manual

carefully and confirm if the overall safety is maintained.

Failure to perform correct operations to change data, program, or the

operation status may result in system malfunction, machine damage, or an

accident.

Remote RUN/STOP for the module installation station’s PLC/CPU is

recommended to use the “Data Exchange during PLC CPU STOP” function

after throughly reading the manual.

If the remote RUN/STOP is executed without using the “Data Exchange

during PLC CPU STOP” function, the output signal from the PLC CPU to the

module goes OFF and the communication line is disconnected (close

processing).

As a result, all data transmission from other nodes, including status control of

the PLC CPU, becomes impossible.

CAUTION

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