SAFETY PRECAUTIONS 
(Be sure to read these instructions before using the product.)
Before using this product, read this manual and the relevant manuals introduced in this manual carefully
and handle the product correctly with full attention to safety.
Note that these precautions apply only to this product. Refer to the user's manual of the CPU module for
safety precautions on programmable controller systems.
In this manual, the safety instructions are ranked as " WARNING " and " CAUTION".
WARNING
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.
Note that failure to observe the !CAUTION level instructions may also lead to serious results depending
on the circumstances.
Be sure to observe the instructions of both levels to ensure personal safety.
Please keep this manual in accessible place and be sure to forward it to the end user.
[Design Instructions]
!WARNING
Make sure to see this manual for information about each station's operating status when a
communication error occurs in the network. Erroneous outputs and malfunctions may result in
serious accidents.
If a coaxial cable is disconnected, this may destabilize the line, and a data link communication
error may occur in multiple stations. Make sure to create an interlock circuit in the sequence
program so that the system will operate safely even if the above error occurs. Failure to do so
may result in a serous accident due to faulty output or malfunctions.
Provide a safety circuit outside the programmable controller so that the entire system will
operate on the safety side even when an error occurs with the personal computer.
There is a risk of an accident due to faulty output or malfunctioning.
(1) Construct circuits outside the programmable controller, including an emergency stop circuit,
protection circuit, interlock circuit for reciprocal operations such as forward and reverse, and
interlock circuit for positioning high and low limits to prevent damage to the equipment.
(2) If the station in which the board is installed is disconnected from the data link due to a data
link error, the data output from that station and written in other stations will remain the same
as immediately before the error occurred in the data link. This data will be retained until the
data link for that station is reopened (returned to system).
Provide a mechanism to monitor the status of data link and handle errors for each station
that is connected to the data link system.

A - 2 A - 2
[Design Instructions]
!CAUTION
Do not bunch the control wires or communication cables with the main circuit or power wires, or
install them close to each other.
They should be installed 100 mm (3.94 inch) or more from each other.
Not doing so could result in noise that would cause malfunctioning.
[Installation Instructions]
!CAUTION
Use the board in an environment as described in the general specifications listed in this
operating manual.
If the board is used in an environment outside the ranges described in the general
specifications, it may result in an electric shock, fire, malfunctioning, damage to or deterioration
of the product.
Be sure to shut off all phases of the external power supply used by the system before installing
or removing the board. If all power is not turned off, this will result in failure of the board or
malfunctioning.
Install the board to a personal computer which is compliant with PCI standard or PCI ExpressR
standard (Refer to "Section 2.5 Operating Environment"). Failure to do so may cause a failure or
malfunction.
Securely mount the board to the PCI slot of the mounting device.
If the board is not mounted correctly, this may lead to malfunctioning, failure or cause the board
to fall.
Insert the communication cable securely into the board connector. After it has been inserted,
check to make sure that it is not being lifted up.
A faulty connection can lead to faulty input or output.
When mounting the board, take care not to become injured by the components that are installed
or surrounding materials.

[Wiring Instructions]
!WARNING
Be sure to shut off all phases of the external power supply used by the system before
performing work such as installing the board and wiring.
If all power is not turned off, there is a risk of electric shock or damage to the product.
When turning on the power and operating the module after having installed the board and doing
the wiring, always attach the cover for the device module in which the board is installed.
There is a risk of electric shock if the module cover is not attached.
!CAUTION
Properly solder the parts of a soldering-type coaxial cable connector. Incomplete soldering may
result in malfunction.
Crimp the parts of a crimping-type coaxial cable connector with proper force at a proper position.
Failure to do so may cause drop of the cable or malfunction.
For the communication cable, specialized skills and tools are required to connect the plug and
cable. The connector plug itself is a custom part.
When purchasing, consult your local Mitsubishi representative.
If the connection is incomplete, this can result in a short, fire or malfunction.
Be sure to fix communication cables connecting to the board by placing them in the duct or
clamping them.
Cables not placed in the duct or without clamping may be hang freely and accidentally pulled,
which may cause damage to the board or cable, or malfunction due to bad cable contacts.
When removing the cable from the board, do not pull the cable.
Pulling the cable that is still connected to the board may cause damage to the board or cable, or
malfunction due to bad cable contacts.
Prevent foreign matter such as chips or wiring debris from getting on the board.
Failure to do so can result in fire, breakdowns or malfunction.
Verify the rated voltage and pin assignment of the product and connect the external power
supply cable properly.
Connecting a power supply with a different voltage rating, imperfect cable crimping or faulty
wiring may cause a fire or failure.
Use a specified tool for crimping of the cable and contacting pin. Imperfect crimping may cause
malfunction.
Verify the pin assignment and fully insert the crimped contacting pin into the connector.
