(Read these precautions before using.)
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 Mitsubishi equipment. Refer to the
CPU module user's manual for a description of the PC system safety
precautions.
These
z
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

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
z
Configure a safety circuit external to the PC, so that the entire
system operates safety even if there is an external power error or if
the PC is malfunctioning.
[Design precautions]
CAUTION
z
Do not bundle, or near the control cables and communication cables with
the main circuit and power cables. Keep them at least 100mm
(3.94inch) away from such cables. Noise may cause malfunction.
[Installation precautions]
CAUTION
z
Use the PC in the environment given in the general specifications of the
this manual. Using the PC outside the range of the general
specifications may result in electric shock, fire or malfunctioning. or may
damage or degrade the module.
z
Insert the tabs at the bottom of the module into the mounting holes in the
base module before installing the module, and after tightening the
module fixing screws with specified torque. If the connector is not
property installed and tightened. If may result in malfunctioning, failure
or cause the module to lam out.
Tightening the screws too far may cause damage to the screw and/or the
module, resulting in fall out, short circuit or malfunctions.
z
Do not directly touch the module’s conductive parts or electronic
components. Doing so could cause malfunction or failure in the module.
z
Insert the wire breakage detection connector installation screw into the
mounting holes in the module, and after tightening the connector
installation screw with specified toque. If the connector is not property
installed and tightened, it may result in error detetion of wire breakage.
[Wiring precautions]
CAUTION
z
Be sure to ground the shield wire with a special PC ground of Type III or
above. Not doing so could result in malfunction.
z
When wiring in the PC, be sure that it is done correctly by checking the
product's rated voltage and the terminal layout. Connecting a power
supply that is different from the rating or incorrectly wiring the product
could result in fire or failure.
z
Tighten the terminal screws with specified torque. Loose terminal screws
may cause a short circuit, fire, or malfunction.
Tightening the terminal screws too far may cause damage to the screw
and/or the module, resulting in short circuit, or malfunctions.
z
Be sure that cuttings, wire chips, or other foreign matter do not enter the
module. Foreign matter may start a fire or cause failure or malfunctions.
z
Be sure to fix communication cables and power 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, allowing them to be
accidentally pulled, which may result in a module malfunction and cable
damage.
z
When detaching the communication 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 cables without connectors,
first loosen the screw at the junction, then detach to the cable. Pulling
the cable portion while it is connected to the module may cause a
malfunction or damage to the module and cable.
[Starting and maintenance precautions]
CAUTION
z
Do not touch the terminal while the power is on.
It may cause malfunction.
z
Make sure to switch all phases of the external power supply off before
cleaning or re-tightening the terminal screws. If you do not switch off the
external power supply, it will cause failure or malfunction of the module.
z
Never disassemble or modify the module. This may cause failure,
malfunctioning, injury and/or fire.
z
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 failure or malfunction of the module.
[Disposal precaution]
CAUTION
z
When disposing of this product, handle it as industrial waste.
