DANGER
CAUTION
zSAFETY PRECAUTIONS z
(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
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]
CAUTION
zWhen 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
zUse 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.
zInstall 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.
zTighten 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.
zMake 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.
zDo not touch the electronic parts or the module conducting area directly.
It may cause erroneous operation or failure.

A- 3
[WIRING PRECAUTIONS]
CAUTION
zPerform 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.
zAttach connector to the module securely.
zBe 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.
zTighten 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.
zDo 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.
zSolder coaxial cable connectors properly.
Insufficient soldering may cause malfunction.
zBe 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.
