[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.

DANGER

CAUTION

[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.

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.

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.

3.1 Cable length restrictions between stations

(1) The main modules case is made of plastic, so do not drop it or subject it to

strong impacts.

(2) Do not dismount the printed wiring board from the case. It may damage the

module.
