[Design Precautions]
[Installation Precautions]
DANGER
In the case of a data link error, the master module data is backed up.
Using the communication status information, create an interlock circuit on the
sequence program for the system to operate safely.
CAUTION
Do not install the control or communication cable(s) together with the main
circuit or power cables.
Keep a distance of 100mm or more between them.
Failure to do so may cause malfunctions due to noise.
CAUTION
Use the module in an environment that meets the general specifications
given in this manual.
Operating it in any other environment may cause an electric shock, fire,
malfunction, product damage or deterioration.
For protection of the switches, do not remove the cushioning material before
installation.
Securely fix the module with the DIN rail or fixing screws. Fixing screws must
be tighten within the specified torque range.
A loose screw may cause a drop of the module or malfunction.
Overtightening may damage the screw, resulting in a drop or malfunction of
the module.
Do not directly touch any conductive part of the module.
Doing so may result in a malfunction or failure of the module.

A-3
[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 a damage to the product and/or malfunctions.
Always ground the FG terminal to the protective ground conductor.
Failure to do so may result in malfunctions.
Be sure to tighten any unused terminal screws within a tightening torque
range.
Failure to do so may cause a short circuit due to contact with a solderless
terminal.
Use applicable solderless terminals and tighten them with the specified
torque.
If any solderless spade terminal is used, it may be disconnected when the
terminal screw comes loose, resulting in failure.
Check the rated voltage and terminal layout and then wire the module
correctly.
Connecting a power supply of a different voltage rating or incorrect wiring
may cause a fire or failure.
Tighten terminal screws within the specified torque range.
A loose terminal screw may cause a short circuit or malfunction.
Overtightening can cause a short circuit or malfunction due to damage of the
screws or module.
Take care to prevent foreign matter such as dust or wire chips from entering
the module.
Failure to do so may cause a fire, failure or malfunctions.
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.

[Wiring Precautions]
[Starting and Maintenance Precautions]
[Disposal Precautions]
CAUTION
Do not install the control cable(s) together with the communication cable(s).
Doing so may cause malfunctions due to noise.
When disconnecting the cables from the module, do not hold and pull the
cable part.
Disconnect the cables after loosening the screws in the portions connected
to the module.
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.
CAUTION
Do not touch the terminals while the power is on.
Doing so may cause malfunction.
Be sure to shut off all phases of the external power supply used by the
system before cleaning or retightening the terminal screws.
Not doing so can cause the module to fail or malfunction.
Undertightening can cause a drop, short circuit or malfunction.
Overtightening can cause a drop, short circuit or malfunction due to damage
of the screws or module.
Never disassemble or modify the module.
This may cause breakdowns, malfunction, injury and/or fire.
Do not drop or apply any strong impact to the module.
Doing so may damage the module.
Be sure to shut off all phases of the external power supply used by the
system before mounting or dismounting the module to or from the panel.
Not doing so can cause the module to fail or malfunction.
Do not install/remove the terminal block more than 50 times after the first use
of the product. (IEC 61131-2 compliant)
Before handling the module, always touch grounded metal, etc. to discharge
static electricity from the human body.
Failure to do so can cause the module to fail or malfunction.
CAUTION
When disposing of this product, treat it as industrial waste.

4. LOADING AND INSTALLATION
4.1 Handling Precautions
The following is an explanation of handling precautions of the
AJ65SBT2B-64RD3.
CAUTION
Do not touch the terminals while the power is on. Doing so may cause
malfunction.
Take care to prevent foreign matter such as dust or wire chips from entering
the module. Failure to do so may cause a fire, failure or malfunctions.
Never disassemble or modify the module. This may cause breakdowns,
malfunctioning, injury and/or fire.
Do not directly touch the conductive area or electronic components of the
module. Doing so may cause malfunction or failure in the module.
Because it is made of resin, do not drop or apply any strong impact to the
module. Doing so may damage the module.
Tighten terminal screws within the specified torque range.
A loose terminal screw may cause a short circuit or malfunction.
Overtightening a terminal screw may damage the screw, resulting in a short
circuit or malfunction.
When disposing of this product, treat it as industrial waste.
Use the module in an environment that meets the general specifications
given in this manual. Operating it in any other environment may cause an
electric shock, fire, malfunction, product damage or deterioration.
For protection of the switches, do not remove the cushioning material before
installation.
Securely fix the module with the DIN rail or installation screws. Installation
screws must be tighten within the specified torque range.
A loose screw may cause a drop of the module or malfunction.
Overtightening may damage the screw, resulting in a drop of the module or
malfunction.
Be sure to shut off all phases of the external power supply used by the
system before mounting or dismounting the module to or from the panel.
Not doing so can cause the module to fail or malfunction.
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.

5.3 Connection of Terminating Resistor
The AJ65SBT2B-64RD3 stores the terminating resister of 110 , so
there is no need the external wiring
(1) Precautions
(a) Move the L TER. switch until it clicks.
(b) Make sure that between DA and DB is high resistance (when
the L TER. switch is off) or is 110 (When the L TER. switch is
on) with a tester before wiring the system with CC-Link
dedicated cables.
(c) The built-in terminating resistor cannot be used in the following
cases. Wire a terminating resistor (110 or 130 ).
• A CC-Link system is configured using CC-Link cables of
130 .
• The AJ65SBT2B-64RD3 may be replaced during data link.

6. WIRING
6.1 Wiring Precautions
External wiring that is less susceptible to noise is required as a
condition of enabling a highly reliable system and making full use of the
capabilities of AJ65SBT2B-64RD3.
The precautions when performing external wiring are as follows:
(1) Use separate cables for the AC control circuit and the external
input signals of the AJ65SBT2B-64RD3 to avoid the influence of
the AC side surges and inductions.
(2) Always place the RTD at least 10cm away from the main circuit
cables and AC control circuit lines. Fully keep it away from high-
voltage cables and circuits, which include high frequency waves,
such as an inverter's load circuit. Not doing so will cause the
module more susceptible to noises, surges and inductions.
(3) The shield wire or the shield of the shielded cable must be
grounded at one end. However, Grounding outside may be suitable
depending on the noise circumstances.
6.2 Wiring with RTD
The method for connecting between the AJ65SBT2B-64RD3 and the
RTD. is shown in figure 6.1.
