•SAFETY PRECAUTIONS •
(Read these precautions before using.)
When using Mitsubishi equipment, thoroughly read this manual and the associated manuals introduced in
this manual.
Also pay careful attention to safety and handle the module properly. These precautions apply only to
Mitsubishi equipment. Refer to the user’s manual of the CPU module to use for a description of the PLC
system safety precautions.
These •SAFETY PRECAUTIONS •classify the safety precautions into two categories: "DANGER" and
"CAUTION".
DANGER
CAUTION
Procedures which may lead to a dangerous condition and cause 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 !CAUTION may also be linked 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]
!DANGER
•Read Chapter 5 in this manual carefully for status of each station when the PC CPU has
stopped its operation and when a communication error occurred in the data link.
Configure an interlocking circuit in a sequence program using the communication status
information (SB, SW) so that the safety of the overall system is always maintained.
Accident may occur due to output error or malfunctioning.
•An error is not detected by the master station nor local station when a station specified as an
error-invalid station is in a communication error status.
!CAUTION
•Do not bundle, on install, the control cables and communication cables with, or near, main circuit
and power cables. Keep them at least 100mm (3.9 inch) away from such cables. Noise may
cause erroneous operation.

A - 2
[INSTALLATION PRECAUTIONS]
!CAUTION
•Use the PC in the environment given in the general specifications section of this manual. Using
the PC outside the range of the general specifications may result in electric shock, fire, or
erroneous operation or may damage or degrade the product.
•Insert the tabs at the bottom of the module into the holes in the base unit before installing the
module. (Modules in AnS series, make sure screws are securely tightened to base unit with
specified torques.)
Improper installation may cause erroneous operation, accidents, or the module to fall out.
•Do not directly touch the module's conductive parts or electronic components.
Doing so could cause malfunction or trouble in the module.
[PRECAUTIONS REGARDING WIRING]
!DANGER
•Completely turn off the external power supply when installing or placing wiring. Failing to
completely shut out the power supply phases could cause electrical shock and/or damage to the
product.
•Following installation or wiring work, when turning on the power supply and operating the
equipment, make sure the terminal cover provided as an accessory has been attached to the
product.
[WIRING PRECAUTIONS]
!CAUTION
•Tighten the terminal screws by the specified torque.
Loose terminal screws may cause a short circuit or erroneous operation.
Overtightening of screws can cause damages to the screws and/or the module, resulting in
fallout, short circuits, or 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.
•Be sure to fix the wires or cables by ducts or clamps when connecting them to the module.
Cables not placed in the duct or without clamping may hang or shift, allowing them to be
accidentally pulled, which may result in a malfunction or damage to the module and cable.
•Do not install the control lines together with the communication cables, or bring them close to
each other. Failure to do so may cause malfunctions due to noise.
•When detaching the communication cable or power cable from the module, do not pull the cable
portion. For cables with connectors, hold the connector at the junction to the module, then
detach it. For connectors without connectors, first loosen the screw at the junction, then detach
the cable.
Pulling the cable portion while it is connected to the module may cause a malfunction or damage
to the module and cable.

A - 3
[STARTING AND MAINTENANCE PRECAUTIONS]
!CAUTION
•Do not touch any terminal without turning off all phases of the external power supply used in the
system.
It may cause erroneous operation.
•Be sure to shut off all phases of the external power supply before cleaning or retightening the
terminal screws. Doing this work while the power is on may damage the module or cause
erroneous operation.
•Do not disassemble or rebuild the module.
It may cause accidents, erroneous operation, injury, or fire.
•Be sure to shut off all phases of the external power supply used by the system before mounting
or removing the module.
Mounting or dismounting the module whhile the power is on may damage the module or cause
erroneous operation.
•Do not mount/remove the module onto/from base unit more than 50 times
(IEC61131-2-compliant), after the first use of the product.
•Always make sure to touch the grounded metal to discharge the electricity charged in the
electricity charged in the body, etc., before touching the module.
Failure to do say cause a failure or malfunctions of the module.
[DISPOSAL PRECAUTIONS]
!CAUTION
•When disposing of this product, handle it as industrial waste.
