SAFETY PRECAUTIONS
(Read these precautions before using this product.)
Before using this product, please read this manual and the relevant manuals
carefully and pay full attention to safety to handle the product correctly.
In this manual, the safety precautions are classified into two levels:
" WARNING" and " CAUTION".
Under some circumstances, failure to observe the precautions given under
" CAUTION" may lead to serious consequences.
Observe the precautions of both levels because they are important for personal
and system safety.
Make sure that the end users read this manual and then keep the manual in a safe
place for future reference.
[DESIGN PRECAUTIONS]
WARNING
When a communication error occurs in the PROFIBUS-DP, the status of the
faulty station is as follows. Configure an interlock circuit in the sequence
program using the communication status information (input X1) so that the
system can operate safely.
Erroneous outputs and mis-operation could cause accidents.
(1) The input data from the master station remains unchanged from the data
prior to the communication error.
(2) When the master station becomes faulty, the output status of the
A1SJ71PB93D will be as in the parameter settings of the master station.
(3) When any A1SJ71PB93D is down, the output state of other slave stations
will be in accordance with the parameter settings of the master station.
WARNING
Indicates that incorrect handling may cause
hazardous conditions, resulting in death or severe
injury.
Indicates that incorrect handling may cause
hazardous conditions, resulting in minor or moderate
injury or property damage.
CAUTION

A-2
[DESIGN PRECAUTIONS]
[INSTALLATION PRECAUTIONS]
WARNING
Do not output the "prohibited to use" signal as the output signal to a special
function module from the programmable controller CPU.
Writing data into the "system area" or outputting a signal for "prohibited to
use" may cause system malfunction in the programmable controller.
CAUTION
When the PROFIBUS cable is laid, do not lay it close to main circuits or
power lines. They should be installed 100mm(3.9inch) or more from each
other. Not doing so could result in noise that would cause malfunctioning.
CAUTION
Use the PLC in an environment that meets the general specifications
contained in the CPU user's manual.
Using this PLC in an environment outside the range of the general
specifications may cause electric shock, fire, malfunction, and damage to or
deterioration of the product.
Load the module by securely inserting the module fixing hook at the bottom
of the module into the fixing hole of the base unit.
Always screw the module to the base unit to the specified torque.
Tighten the screws within the range of specified torque.
If the screws are loose, it may cause the module to fallout, short circuits, or
malfunction.
If the screws are tightened too much, it may cause damage to the screw and/
or the module, resulting in fallout, short circuits or malfunction.
Switch all phases of the external power supply off when mounting or
removing the module.
Not ding so may cause electric shock or damage to the module.
Do not touch the conductive area or electric parts of the module.
Doing so may cause module malfunctioning or breakdowns.

A-3
[WIRING PRECAUTIONS]
[STARTING AND MAINTENANCE PRECAUTIONS]
CAUTION
Switch all phases of the external power supply of the PLC system off before
connecting the PROFIBUS cable. If you not switch off the external power
supply, it will cause failure or malfunction of the module.
Be careful not to let foreign matter such as filings or wire chips get inside the
module. These can cause fire, breakdowns and malfunctioning.
The PROFIBUS cable which is connected to the module must be protected
with a duct or secured in position with clamps.
Unless the cable is thus protected or secured, the module or the cable could
be damaged when the cable swings, moves or it is strained with careless
pulls, or it could cause malfunction when the cable contacts with any
undesirable objects.
When disconnecting the PROFIBUS cable from the module, do not pull by
holding the cable section. To disconnect the cable, make sure to hold the
connector which is coupled with the module. Do not attempt to pull the cable
to disconnect it from the module. It could damage the module or the cable, or
cause malfunction due to a poor contact of the cable.
WARNING
Before cleaning, be sure to shut off all phases of the external power supply
used by the system.
Failure to do so may cause electrical shocks.

A-4
[STARTING AND MAINTENANCE PRECAUTIONS]
[DISPOSAL PRECAUTIONS]
CAUTION
Never disassemble or modify the module.
This may cause breakdowns, malfunctioning, injury and/or fire.
When using a wireless communication device such as a cellular phone, keep
a distance of 25cm (9.85 inch) or more from the programmable controller in
all directions. Failure to do so can cause a malfunction.
Be sure to shut off all phases of the external power supply before mounting
or removing the module.
Failure to do so may result in failure or malfunctions of the module.
Always make sure to touch the grounded metal to discharge the electricity
charged in the body, etc., before touching the module.
Failure to do so may cause a failure or malfunctions of the module..
CAUTION
When disposing of this product, treat it as industrial waste.

3. INSTALLATION
The following section explains the precautions when handling the
A1SJ71PB93D, from the time they are unpacked until they are installed.
For more details on the module installation, see the user's manual for
the PLC CPU used.
3.1 Handling Precautions
(1) Do not drop the module case or subject it to heavy impact since it is
made of resin.
(2) Do not remove the PCB of each module from its case. This may
cause a failure in the module.
(3) Be careful not to let foreign objects such as wire burrs enter the
module during wiring. In the event any foreign object enters,
remove it immediately.
(4) Tighten the module mounting screws and connector mounting
screws using torque within the following ranges.
Screw location Tightening torque range
Module mounting screws (M4 screws) 78.4 to 117.6 N • cm
PROFIBUS cable connector mounting screws
(#4 - 40UCN) 20 to 28 N • cm

5. WIRING
5.1 Precautions Against Wiring
As one of the requirements to give full play to A1SJ71PB93D’s functions
and make up the system with high reliability, it is necessary to have an
external wiring unsusceptible to an influence of noise. Precautions
against external wiring of A1SJ71PB93D is described below.
(1) Do not route the wire of A1SJ71PB93D close to or bundle it
together with the main circuit and high-tension lines, or the load-
carrying lines from other than the PLC. Otherwise, the module may
be susceptible to an influence of noise and surge induction.
(2) The wires from the input/output modules of the PLC should be
away from the communication cable as far as possible as shown in
the figure below.
(3) Grounding
(a) When the A1SJ71PB93D is used, the FG and LG terminals of
the power supply module of the PLC should basically be
grounded.
(b) If communication cannot be performed after grounding
because of abnormal voltage applied to the FG terminal, the
module may be used without grounding.
