SAFETY PRECAUTIONS
(Always read before starting use)
When using Mitsubishi equipment, thoroughly read this manual and the associated manuals
introduced in the manual. Also pay careful attention to safety and handle the module
properly.
These precautions apply only to the installation of Mitsubishi equipment and the wiring with
the external device. Refer to the user’s manual of the CPU module to be used for a
description of the PLC system safety precautions.
These SAFETY PRECAUTIONS classify the safety precautions into two categories:
"DANGER" and "CAUTION".
Procedures which may lead to a dangerous condition and cause
DANGER
CAUTION
death or serious injury if not carried out properly.
Procedures which may lead to a dangerous condition and cause
superficial to medium injury, or physical damage only, if not
carried out properly.
!
Depending on circumstances, procedures indicated by
to serious results.
In any case, it is important to follow the directions for usage.
Store this manual in a safe place so that you can take it out and read it whenever necessary.
Always forward it to the end user.

[DESIGN PRECAUTIONS]
CAUTION
When laying the control wire or communication cable, do not bundle with or place near
!
main circuit or power line.
Keep them at least 100 mm (3.94 in.) away from such cables.
Noise may cause erroneous operation.
[INSTALLATION PRECAUTIONS]
CAUTION
Use the PLC in the environment given in the general specifications section of the user's
!
manual to be used. Using the PLC outside the range of the general specifications may
result in electric shock, fire, or erroneous operation or may damage or degrade the
product.
A- 1
[INSTALLATION PRECAUTIONS]
CAUTION
! Install so that the tabs at the bottom of the module fit securely into the base unit
mounting holes. (The AnS series module shall be fastened by screws in the base unit at
the specified torque.)
Not installing the module correctly could result in erroneous operation, damage, or
pieces of the product falling.
! Tighten the screw within the range of specified torque.
If the screws are loose, it may result in fallout, short circuits or malfunction.
Tightening the screws to far may cause damage to the screw and/or the module,
resulting in fallout, short circuits or malfunction.
! Make sure to switch all phases of the external power supply off before mounting or
removing the module.
If you do not switch off the external power supply, it will cause electric shock or damage
to the product.
! Do not touch the electronic parts or the module conducting area directly.
It may cause erroneous operation or failure.
[WIRING PRECAUTIONS]
CAUTION
! Perform correct pressure-displacement, crimp-contact or soldering for external wire
connections using the tools specified by the manufactures. Incorrect connection may
cause short circuits, fire or malfunction.
! Attach connector to the module securely.
! Be sure to fix communication cables or power supply cables leading from the module by
placing them in the duct or clamping them. Cables not placed in the duct or without
clamping may hang or shift, alllowing them to be accidentally pulled, which may cause a
module malfunction and cable damage.
! Tighten the screw within the range of specified torque.
If the screws are loose, it may result in short circuits or malfunction.
Tightening the screws to far may cause damage to the screw and/or the module,
resulting in fallout, short circuits or malfunction.
! Do not grab on the cable when removing the communication cable connected to the
module.
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 part that is connected to the terminal block.
Pulling the cable that is still connected to the module may cause a malfunction or
damage to the module or cable.
! Solder coaxial cable connectors properly.
Insufficient soldering may cause malfunction.
! Be sure that cuttings, wire chips, or other foreign matter do not enter the module.
Foreign matter may start a fire or cause an accident or erroneous operation.

4. Loading and Installation
The following is explanations of the handling precautions and installation environment
which is common to modules when handling E71 from unpacking to installation.
For the details of loading and installation of the module, refer to User’s Manual of CPU
module to be used.
4.1 Handling Precautions
The following is an explanation of handling precautions of the module.
(1) Because the case of the module is made of resin, be careful not to drop it or expose it
to strong impact.
(2) Execute tightening of the module's installation screws within the range indicated
below.

5. Connection to a Network
The following is an explanation of the connection method of the E71 to the 10 BASE-T,
10BASE5 or the 10BASE2.
Point
(1) Installation procedures of the network require sufficient safety measures. For the
execution of such operations as terminal processing of connection cable, trunk line
cable etc., please consult with a trained professional.
(2) When the customer's products match the EMC instructions and the low voltage
instructions for connecting E71, use the method in (4) below to install the ferrite core.
(3) When there is a communication error caused by high frequency noise due to the
installation environment, take the following steps.
• The ferrite core can be installed using the steps in (4) below.
• When communicating with TCP/IP, increase the count of communication retries.
• When connecting to 10 BASE-T, use an unshield twisted pair cable (UTP category 5).
• When connecting to 10BASE2, use a double shielded coaxial cable.
Shield
• When connecting to 10BASE5 or 10BASE2, ground the shield of the coaxial cable
at both the local station and companion connected device. (Ground at a place near
the connector.)
(4) Below are the steps for installing the ferrite core based on connection to the 10BASE5
network.
Please install the ferrite core ( 1) on the side of the E71 or external devices / the AUI
cables transceiver.
1 It is possible to use a TDK Corporation style ZCAT 2032-0930.

(5) When using A1SJ71E71N-B5T, when the FG signal is regulated on the side of the
external power supply of the original power supply for the transceiver, ground the FG
signal at the original power supply.

2 Use a transceiver with a function that is generally called SQETEST or heart beat (a
transceiver function that emits signals to notify whether the transceiver is operating
normally at the end of communication).
5.3 Connecting to the 10BASE2 (AJ71E71N-B2, A1SJ71E71N-B2)
<Connection procedure> ( 2)
1) Push in the connector by aligning the
groove [1] and tab [2] as shown in the
