[INSTALLATION PRECAUTIONS]
CAUTION
zUse the PLC in an environment that meets the general specificaitons
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.
zFully insert the projection on the bottom of the module into the hole in the
base unit, press the module into position, and tighten the module fixing
screws.
Not installing the module correctly or not fixing it with the screws could result
in malfunction, damage, or drop of some pieces of the product.
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.
zCompletely 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.

[INSTALLATION PRECAUTIONS]
CAUTION
zDo not directly touch the printed circuit board, the conducting parts and
electronic parts of the module. It may cause damage or erroneous operation.
zBefore 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.
[WIRING PRECAUTIONS]
DANGER
zBefore installation or 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
zSolder the coaxial cable connector properly. Incomplete soldering may
cause a malfunction.
zBe sure there are no foreign substances such as sawdust or wiring debris
inside the module. Such debris could cause fires, damage, or erroneous
operation.
zMake 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.
zWhen 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 A1SJ72QLP25,
A1SJ72QLR25 and A1SJ72QBR15 model MELSECNET/10 network modules
(abbreviated as Network Modules) which are used to construct remote I/O
systems on MELSEC-QnA 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 A1SJ72QBR15 does not
come with terminal resistors.
