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.
