z SAFETY PRECAUTIONS z
(Always read before starting use.)
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 CPU
module user's manual.
In this manual, the safety instructions are ranked as "DANGER" and
"CAUTION".
Indicates that incorrect handling may cause hazardous
DANGER conditions, resulting in death or severe injury.
Indicates that incorrect handling may cause hazardous
CAUTION conditions, resulting in medium or slight personal injury or
physical damage.
CAUTION level may lead to a serious consequence according
Note that the
to the circumstances.
Always follow the instructions of both levels because they are important to
personal safety.
Please store this manual in a safe place and make it accessible when required.
Always forward it to the end user.
[INSTALLATION PRECAUTIONS]
CAUTION
z Use the PLC in an environment that meets the general specifications
contained in CPU module user’s manual. Using this PLC 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.
z Fully insert the projection on the bottom of the module into the hole in the
base unit and press the module into position.
Not installing the module correctly could result in malfunction, damage, or
drop of some pieces of the product.
If using the product in a vibratory environment, tighten the module with the
screws.
Always tighten the module fixing screws within the specified torque range.
Loose tightening could result in drop of some pieces of the product,
short-circuit, and malfunction.
Tightening the screws too much could result in drop of some pieces of the
product, short-circuit, or malfunction due to the breakage of a screw or the
module.
[INSTALLATION PRECAUTIONS]
CAUTION
z Do not directly touch the printed circuit board, the conducting parts and electronic
parts of the module. It may cause damage or erroneous operation.
z Before handling the module, touch a grounded metal object to discharge the
static electricity from the human body. Failure to do so may cause malfunction or
failure of the module.
z Completely turn off the externally supplied power used in the system before
mounting or removing the module.
Not doing so could result in damage to the product.
[WIRING PRECAUTIONS]
DANGER
z Before wiring, be sure to shut off all phases of the external power supply used by
the system.
Failure to do so may cause electric shocks or damage the product.
CAUTION
z 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.
z Solder the coaxial cable connector properly. Incomplete soldering may cause a
malfunction.
z Make sure to place the communication and power cables into a duct or fasten
them using a clamp.
Cables not placed in the duct or not clamped may hang or shift, allowing them to
be accidentally pulled, which may cause a module malfunction and cable
damage.
z When removing the communication cable or power cables from the module, do
not pull the cable. 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 terminal block. Pulling the
cable that is still connected to the module may cause malfunction or damage to
the module or cable.

Compliance with the EMC Directive and the Low Voltage Directive
When incorporating the Mitsubishi PLC into other industrial machinery or equipment
and keeping compliance with the EMC and low voltage directives, refer to Chapter 3
"EMC Directive and Low Voltage Instruction" of the User’s Manual (Hardware) for the
CPU module used or the PLC CPU supplied with the base unit.
The CE logo is printed on the rating plate of the PLC, indicating compliance with the
EMC and low voltage directives.
For making this product compliant with the EMC and low voltage directives, please
refer to Section 3.1.3 "Cable" in Chapter 3 of the above-mentioned user’s manual.
1. Overview
This manual explains the specifications and part names of the AJ72LP25 and
AJ72BR15 model MELSECNET/10 network modules (abbreviated as Network
Modules) which are used to construct remote I/O systems on MELSEC-A series
MELSECNET/10 network systems.
(1) The use, cable used and installation position of the Network Modules are
indicated on the following chart.

(3) The coaxial bus-type network system requires terminal resistors (A6RCON-R75:
75 ) at both terminal stations of the network. The user should arrange for
terminal resistors, since the AJ72BR15 does not come with terminal resistors.
(4) When applying the remote I/O network, make sure to use the following software

Please refer to the reference manual of used master module for the wiring for network
system.
Please wire IN/OUT or SD/RD of the connector for the cable correctly.
Please do loopback test, the set confirmation test, and the bureau order confirmation
test after wiring. It might be generated that a baton abnormal passing cannot be
generated when miswiring and the downed bureau which cannot do the loopback of an
arbitrary bureau do the row again even by the reclosing of the power supply.
