WARNING
CAUTION
zSAFETY PRECAUTIONS z
(Read these precautions before using.)
Before using this product, please read this manual and the relevant manuals
carefully and pay full attention to safety to handle the product correctly.
These precautions apply only to Mitsubishi equipment. Refer to the CPU
module user's manual for a description of the programmable controller system
safety precautions.
In this manual, the safety precautions are classified into two levels:
"WARNING" and " CAUTION".
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.
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
zIf a communication error occurs in the AS-i system, the input will turn OFF
from the slave having the communication error.
Output to the slave with communication error will be held or cleared
depending on the slave specifications.
The AS-i system communication error can be confirmed with the buffer
memory's List of Active Slaves (LAS) (15 to 16H, 75 to 76H) and with the
input signal Config OK (X4, X9).
Using the above information, configure an interlock circuit on the sequence
program so that the system activates safely.
There is a risk of accidents caused by incorrect outputs or incorrect
operations.
zDepending on the unit fault, the input/output could enter the ON state or
OFF state.
Provide a circuit for external monitoring for input/output signals that could
lead to major accidents.
CAUTION
zDo not bundle AS-i cable together with main circuit or power lines, or lay
them close to these lines.
As a guide, separate these lines by a distance of at least 100 mm,
otherwise malfunctions may occur due to noise.

[INSTALLATION PRECAUTIONS]
CAUTION
zUse the programmable controller in an environment that conforms to the
general specifications in CPU module user's manual.
Using the programmable controller in the environments outside the ranges
stated in the general specifications will cause electric shock, fire,
malfunction, or damage to/deterioration of the product.
zDo not touch conductive parts or electronic components of the module with
your bare hands.
This could cause malfunction or failure of the module
zInsert the module fixing projection into the fixing hole in the base unit and
then tighten the module mounting screw within the specified torque. Then
tighten the module mounting screw to the specified torque. Incorrect
installation with no screws could result in malfunction, failure or fall of the
module. Tightening the screw excessively may cause fall, short circuit, or
malfunction of the module due to damage of the screw or the module.
zAlways shut off all phases of the programmable controller power supply
and AS-i power supply externally before mounting or removing the module.
Failure to shut off all phases could lead to product damage.
[WIRING PRECAUTIONS]
WARNING
zSwitch off all phases of the programmable controller power supply and AS-i
power supply outside the programmable controller before starting installing
or wiring work. There is a risk of electric shock or malfunction.
zAlways install the terminal covers enclosed with the product before turning
ON the power or operating the product after installation or wiring.
Failure to install the terminal cover could lead to electric shocks.

[WIRING PRECAUTIONS]
CAUTION
zAlways confirm the products terminal layout before wiring to the module.
Incorrect wiring could lead to fires or faults.
zTighten terminal screws to the specified torque.
If a terminal screw is not tightened to the specified torque, the module may
fall out, short circuit, or malfunction. If a terminal screw is tightened
excessively, exceeding the specified torque, the module may fall out, short
circuit, or malfunction due to breakage of the screw or the module.
zMake sure that no foreign matter such as chips or wire offcuts gets inside
the module. It will cause fire, failure, or malfunction.
zAS-i cables connected to a module must always be run in a duct or held
securely using clamps.
If a cable is not run in a duct or not held securely using clamps, the cable
will sag, move, or be pulled by mistake, which will cause damage to the
module and the cable and also malfunctioning due to loose connection of
the cable.
zWhen removing the AS-i cable from a module, do not pull it out by the cable.
A cable loosen the screws that hold the cable onto the module then
remove the cable.
If the cable is pulled while it is connected to the module, the module and/or
the cable will be damaged and may malfunction due to loose connection of
the cable.
zUse applicable solderless terminals and tighten them within the specified
torque range. If any spade solderless terminal is used, it may be
disconnected when the terminal screw comes loose, resulting in failure.
