always forward it to the end user.
[Design Precautions]
DANGER
If a communication error occurs in the data link, the following will occur
in the station having the communication error.
Use the communication status information, and configure an interlock
circuit in the sequence program so that the system will operate safely.
Incorrect outputs and incorrect operations can lead to accidents.
(1) All points of the general-purpose input from this module will turn
OFF.
(2) All points of the general-purpose output from this module will turn
OFF.
The input/output may turn ON or OFF depending on the module trouble.
Provide a circuit that externally monitors input/output signals that could
lead to serious trouble.
[Design Precautions]
CAUTION
Do not bind the control wire or communication cable with the main circuit or
power wire, or place the control wire near these.
Separate by at least 100mm or more.
Failure to observe this could lead to malfunctions caused by noise.
Always connect the master module and CC-Link dedicated cable at the data
link terminal block.
If the data link terminal block and general-purpose input/output terminal
block are incorrectly inserted, module trouble could occur.

[Mounting Precautions]
CAUTION
Use the module in an environment that meets the general specifications
given in the RS-232C Interface Module Type AJ65BT-R2 User’s Manual.
Using it outside the general specifications could lead to electric shocks,
fires, malfunctioning, product damage or deterioration.
Always connect the crimp, press-fit or solder the connector wire connections
with the maker-designated tools, and securely connect the connector to the
module.
An incomplete connection could lead to short-circuits or malfunctioning.
Do not directly touch the conductive section of the module.
Failure to observe this could lead to module malfunctioning or trouble.
Securely fix the module with the DIN rail or installation screw. Tighten the
installation screw within the designated torque range.
A loose screw could lead to dropping, short-circuiting or malfunctioning.
If the screw is too tight, dropping or short-circuiting could occur due to screw
damage.
Securely mount the connector of each connection cable to the mounting
section.
An incomplete connection could lead to malfunctioning caused by an
incorrect contact.
[Wiring Precautions]
CAUTION
Before starting installation or wiring work, be sure to shut off all phases of
external power supply used by the system.
Failure to shut off all phases could lead to electric shocks, product damage
or malfunctioning.
Always install the terminal covers enclosed with the product before turning
ON the power or operating the product after installation or wiring work.
Failure to install the terminal cover could lead to electric shocks.
Always ground the FG terminal with Class D grounding (Class 3 grounding)
dedicated of the PLC.
Failure to do so could lead to malfunctioning.
Always confirm the product's rated voltage and terminal layout before wiring
the module.
Connecting with a power supply other than the rated power supply, or
incorrect wiring could lead to fires or trouble.
Tighten the terminal screws within the specified torque range.
A loose terminal screw could lead to short-circuiting or malfunctioning.
If the terminal screw is too tight, dropping or short-circuiting could occur due
to screw damage.
Make sure that foreign matter, such as cutting chips or wire scraps, do not
enter the module.
Failure to observe this could lead to fires, trouble or malfunctioning.
The communication cables and power supply cable connected to the
module must be placed in a conduit or fixed with a clamp.
If the cable is not placed in a conduit or fixed with a clamp, the module or
cable could be damaged by the cable variation, movement or unintentional
pulling leading to malfunctioning caused by an improper cable connection.
Do not install the control lines together with the communication cables, or
bring them close to each other. Failure to do so may cause malfunctions
due to noise.
Do not remove the communication cable or power supply cable connected
to the module by pulling on the cable section.
If the cable has a connector, hold the connector at the section connected to
the module, and remove.
If the cable does not have a connector, loosen the screws at the section
connected to the module, and remove.
Pulling on the cable while connected to the module could lead to module or
cable damage, or malfunctioning caused by an improper cable connection.
[Startup/Maintenance Precautions]
CAUTION
When power is ON, do not touch the terminals.
Doing so can cause an electric shock or malfunction.
Before cleaning or tightening the terminal screws and module mounting
screws, be sure to shut off all phases of external power supply used by the
system.
Failure to shut off all phases could lead to module trouble or malfunctioning.
