SAFETY PRECAUTIONS
(Always read these instructions before using this equipment.)
Before using this product, please read this manual and the relevant manuals
introduced in this manual 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 user's
manual for the CPU module used.
In this manual, the safety instructions are ranked as "DANGER" and "CAUTION".
Indicates that incorrect handling may cause
DANGER
CAUTION
Note that the CAUTION level may lead to a serious consequence according
to the circumstances.
Always follow the instructions of both levels because they are important to
personal safety.
Please save this manual to make it accessible when required and always forward
it to the end user.
hazardous conditions, resulting in death or severe
injury.
Indicates that incorrect handling may cause
hazardous conditions, resulting in medium or slight
personal injury or physical damage.
A-1
[Design Precautions]
DANGER
When controlling a running programmable controller (data modification) by
connecting a peripheral to a CPU module or connecting a personal computer
to an intelligent/special function module, create an interlock circuit on the
sequence program so that the whole system will operate safely all the time.
Also, before performing other controls (e.g. program modification, operating
status change (status control)), read this manual carefully and ensure the
safety.
Especially, in the control from an external device to a programmable
controller in a remote location, some programmable-controller-side problems
cannot be resolved immediately due to a data communication failure.
To prevent this, establish corrective procedures for communication failure
between the external device and the programmable controller CPU, as well
as creating an interlock circuit on the sequence program.
In the case of a data link error, the operation status of a faulty station is as
shown below. Using the communication status information, create an
interlock circuit on the sequence program for the system to operate safely.
Incorrect output or malfunction can lead to an accident.
(1) All of general-purpose inputs from this module turn OFF.
(2) All of general-purpose outputs from this module turn OFF.
Depending on the module failure, inputs and outputs may turn ON or OFF
incorrectly.
For I/O signals that may cause a serious accident, provide an external
monitoring circuit.
CAUTION
Do not bunch the control wires or communication cables with the main circuit
or power wires, or install them close to each other.
They should be installed 100 mm (3.94 inch) or more from each other.
Not doing so could result in noise that would cause erroneous operation.
Always use the data link terminal block for connection of a CC-Link dedicated
cable to a master module.
Care must be taken because, if the cable is incorrectly inserted into the
general-purpose I/O terminal block instead of the data link terminal block, the
module will break down.
A-2
[Installation Precautions]
CAUTION
Use the programmable controller in an environment that meets the general
specifications given in this manual.
Using this programmable controller in an environment outside the range of
the general specifications could result in electric shock, fire, erroneous
operation, and damage to or deterioration of the product.
Using a tool specified by the manufacturer, correctly press, crimp, or solder
the wires of the connector and securely connect the connector to the module.
Incomplete connection may cause a short circuit and/or malfunctions.
Do not directly touch the module's conductive parts or electronic
components.
Touching the conductive parts could cause an operation failure or give
damage to the module.
Securely fix the module with the DIN rail or installation screws. Installation
screws must be tightened within the specified torque range.
A loose screw may cause a drop of the module, short circuit or malfunction.
Overtightening may damage the screw, resulting in a drop of the module or a
short circuit.
Completely connect each cable connector to each receptacle.
Incomplete connection may cause a malfunction due to poor contact.
[Wiring Precautions]
CAUTION
Be sure to shut off all phases of the external power supply used by the
system before installation or wiring.
Failure to do so may cause an electric shock, damage to the product and/or
malfunctions.
Attach the terminal cover to the product before energizing and operating the
system after installation or wiring.
Failure to do so may cause an electric shock.
Be sure to ground the FG terminals and LG terminals to the protective
ground conductor.
Failure to do so may result in malfunctions.
A-3
[Wiring Precautions]
CAUTION
When wiring in the programmable controller, be sure that it is done correctly
by checking the product's rated voltage and the terminal layout.
Connecting a power supply that is different from the rating or incorrectly
wiring the product could result in fire or damage.
Tighten the terminal screws with the specified torque.
If the terminal screws are loose, it could result in short circuits, fire, or
erroneous operation.
Overtightening a terminal screw may damage the screw, resulting in a short
circuit or malfunction.
Be sure there are no foreign substances such as sawdust or wiring debris
inside the module.
Such debris could cause fires, damage, or erroneous operation.
Place the connection wires and cables in a duct or clamp them.
If not, dangling cables may swing or inadvertently be pulled, resulting in
damage to the module and/or cables or malfunctions due to poor cable
connection.
Do not install the control cable(s) together with the communication cable(s).
Doing so may cause malfunctions due to noise.
When disconnecting a communication or power cable from the module, do
not pull it by holding the cable part.
For a cable with connector, hold the connector and disconnect it from the
module.
For a cable without connector, loosen the connector screw and disconnect
the cable.
Pulling the cable that is still connected to the module may damage the
module and/or cable and cause malfunctions due to poor cable connection.
Make sure that the interface type is correct before connecting the cable.
Do not connect a cable to a module that has different interface specification.
Doing so will cause a module failure.
Using a tool specified by the manufacturer, correctly press, crimp, or solder
the wires of the connector and securely connect the connector to the module.
Failure to do so may cause a malfunction or failure of the module.

5.2 External Device Connection Method
(1) Connection examples
The AJ65BT-R2N cannot use the CD signal as the control signal for
sending/receiving data to/from the external device.
Wire the CD signal line of the AJ65BT-R2N and external device as
shown in Table 5.1.

(2) Precautions for connection
R
(a) Connect the FG signal line and shield of the RS-232 cable as
follows:
Table 5.3 Precautions for connection
RS-232 cable Connection method Remarks

Shield
Connected to the screw clamp of
the AJ65BT-R2N side connector.
Connected to the screw clamp of
the AJ65BT-R2N side connector.
(Not connected to external
device)
• Do not short-circuit the FG and SG signal
lines of the RS-232 cable.
• If the FG and SG signal lines are
connected inside the external-device
side, do not connect the FG signal line on
the AJ65BT-R2N side to the external
device.
(b) When data communication cannot be performed normally due
to external noise, connect the wires as follows:
1) Connect the FG terminals of both stations with the shield of
the RS-232 cable.
For the external device side, refer to the handling
instructions for the external device.
2) Each signal line (except for SG) must be twisted with the
SG signal line.
3) FG of the AJ65BT-R2N is connected to the screw clamp of
the connector, acting as FG of the module.

(c) Do not connect an RS-422 device to the RS-232 interface.
Doing so will damage the RS-422 interface of the connected
device, resulting in communication failure.
