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
For the operating status of each station after a data link failure, refer to
Chapter 5 in the user's manual.
The master station or local station cannot detect errors when a station
specified as an error-invalidated station becomes communication error.
CAUTION
Do not install the control lines or communication cables together with main
circuit lines or power cables. Keep a distance of 100mm (3.94 inches) or
more between them. Failure to do so may result in malfunction due to noise.
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
[INSTALLATION PRECAUTIONS]
[WIRING PRECAUTIONS]
CAUTION
Use the programmable controller in an environment that meets the
specifications in the user's manual of the CPU module used.
Failure to do so may result in electric shock, fire, malfunction, or damage to
or deterioration of the product.
Insert the tabs at the bottom of the module into the holes in the base unit
before mounting the module.
(For the AnS series modules, tighten the screws to the base unit with the
specified torque.)
Incorrect mounting may cause malfunction, failure, or drop of the module.
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.
WARNING
Shut off the external power supply for the system in all phases before wiring.
Failure to do so may result in electric shock or damage to the product.
After wiring, attach the included terminal cover to the module before turning it
on for operation.
Failure to do so may result in malfunction.

A-3
[WIRING PRECAUTIONS]
CAUTION
Tighten the terminal 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, 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.
Place the cables in a duct or clamp them.
If not, dangling cables may swing or inadvertently be pulled, resulting in
damage to the module or cables or malfunction due to poor contact.
Do not install the control lines and communication cables together with the
main circuit lines or power cables.
Doing so may cause malfunction due to noise.
Use applicable solderless terminals and tighten them within the specified
torque range. If any spade solderless terminal is used, it may be
disconnected when the terminal screw comes loose, resulting in failure.
When disconnecting the cable from the module, do not pull the cable by the
cable part.
When removing the cable with a connector, hold the connector on the side
that is connected to the module.
When removing the cable without a connector, loose the screws on the side
that is connected to the module.
Pulling the cable that is still connected to the module may result in damage to
the module or cable, or malfunction due to poor contact.

A-4
[STARTUP AND MAINTENANCE PRECAUTIONS]
[DISPOSAL PRECAUTIONS]
WARNING
Do not touch any terminal while power is on.
Doing so can cause electric shock.
Shut off the external power supply for the system in all phases before
cleaning the module or retightening the terminal screws or module fixing
screws.
Failure to do so may result in electric shock.
Undertightening can cause drop of screw, short circuit, or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short
circuit, or malfunction.
CAUTION
Do not disassemble or modify the modules. Doing so may cause failure,
malfunction, injury, or a fire.
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.
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 grounded metal object 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.

Point
The setting for the switches (2) to (5) when the module power supply is turned OFF ON
is valid.
When the setting is changed while the module power supply is on, reset the programmable
controller CPU or turn off and then on the module power supply again.
Important
Do not use station number 64 in a system where the waiting master station exists.
When it is used, the station number 64 will not communicate correctly.

4. Loading and Installation
The following is explanations of the handling precautions and
installation environment, which is common to modules when handling
AJ61BT11 and A1SJ61BT11 from unpacking to installation.
For the details of loading and installation of the module, refer to the
user's manual of the programmable controller CPU module used.
4.1 Handling precautions
The following is an explanation of handling precautions of the module.
(1) Do not drop the module case or terminal block, or subject them to
heavy impact since they are made of resin.
(2) Do not remove the print circuit board of each module from its case.
This may cause a failure in the module.
(3) Prevent foreign matter such as dust or wire chips from entering the
module.
Such foreign matter can cause a fire, failure, or malfunction.
(4) Solderless terminals with insulation sleeve cannot be used for the
terminal block. It is recommended that the wiring connecting sections
of the solderless terminals will be covered with a marking tube or an
insulation tube.
(5) 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.
(6) Tighten the module mounting screws and terminal screws within
the following torque range.
(7) Insert the tabs at the bottom of the module into the holes in the
base unit before mounting the module. (For the AnS series
modules, make sure screws are securely tightened to the base unit
with the specified torque.)
Incorrect mounting may cause malfunction, failure, or drop of the
module.
Screw location Tightening torque range
Module mounting screws (M4 screws) 0.78 to 1.18N·m
Terminal-block terminal screws (M3.5 screws) 0.59 to 0.88N·m
Terminal-block installation screws (M3.5 screws) 0.49 to 0.78N·m
