[DESIGN PRECAUTIONS]
DANGER
! When there is a communication error in the data link, the station where the communication is occurring
changes to the following status.
Construct an interlock circuit in the sequence program so that the system will operate on the safety side
using the communication status information.
There is the risk of an accident occurring due to output error or malfunctioning.
(1) All general purpose inputs from this I/F board (A80BDE-J61BT13) are turned off.
(2) All general purpose outputs from this I/F board are turned off.
! A failure in the I/F board may cause I/O to change to on status or off status.
Establish a circuit to be observed externally for those I/O signals that may threaten to cause serious
accident.
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 (3.9 inch) or more from each other.
Not doing so could result in noise that would cause malfunction.

[INSTALLATION PRECAUTIONS]
CAUTION
! Use the I/F 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.
! Do not directly touch the conductive area of the I/F board.
This will result in malfunctioning or failure of the I/F board.
! Fix the I/F board securely with the installation screws and tighten the installation screws within the specified
torque range.
If the screws are loose, this will lead to an error in operation.
If the screws are tightened too much, this will damage the screws and cause a short.
[WIRING PRECAUTIONS]
DANGER
! Always turn off all external power before performing installation, wiring or other work.
If all power is not turned off, there is a risk of electric shock, damage to the product, or malfunctioning.
! When turning on the power and operating the module after installation and wiring are completed, always
attach the terminal cover that comes with the product.
There is a risk of electric shock if the terminal cover is not attached.
[WIRING PRECAUTIONS]
CAUTION
! Always ground the FG terminal on the PC side using D type grounding (Class 3 grounding) or higher
specifically for the PC. Otherwise, there is a risk of malfunctioning.
If a malfunctioning occurs even when the PC unit is grounded, ground both the FG terminal for the PC unit
and the SLD terminal for the I/F board.
! Tighten the terminal screws within the specified torque range.
If the terminal screws are loose, this will lead to a short or malfunctioning.
If the terminal screws are tightened too much, this will damage the screws and I/F board, causing a short or
malfunctioning.
! Take care that foreign objects such as chips or wiring debris do not get inside the I/F board.
This can result in fire, failure or malfunctioning.
! Always house the communication cable and power cable connected to the I/F board in a duct or secure it
using clamps.
If the cables are not housed in a duct or secured with clamps, the cable may dangle, move or be pulled
inadvertently. This can cause damage to the I/F board or cable, or create a faulty contact with the cable
which may lead to.
! When disconnecting the communication or power cable connected to the I/F board, do not grasp and pull
the cable.
First loosen the screws where the cable is connected to the I/F board and then remove the cable.
If the cable is pulled while it is connected to the I/F board, this can cause damage to the I/F board or cable,
or create a faulty contact with the cable and lead to malfunctioning.
A-3
[STARTING AND MAINTENANCE PRECAUTIONS]
DANGER
! Do not touch the terminal when the power is turned on.
This can cause malfunctioning.
! Always turn off all external power before doing any cleaning or re-tightening the terminal screws. If all
power is not turned off, this can cause a failure or malfunctioning of the I/F board.
If the screws are loose, this can cause the terminal to drop, short or operate in error.
If the screws are tightened too much, this can damage the screws and I/F board, causing the terminal to
drop, short or operate in error.
[STARTING AND MAINTENANCE PRECAUTIONS]
CAUTION
! Do not dismantle or rebuild the I/F board.

2. EMC COMMAND MELSEC
2-1
2. EMC COMMAND
2.1 Requirements for EMC Command Compliance
EMC commands, which are among the European command sets, are now enforced. The EMC commands regulate "emission (electromagnetic interference)," which requires that a device not emit strong electromagnetic waves externally, and "immunity (electromagnetic sensitivity)," which requires that a device have the ability to resist external electromagnetic waves. The precautionary items when configuring a machine device using an I/F board to conform to EMC commands are described in sections 2.1.1 through 2.1.4. Although we tried very hard to document these materials according to the requirements for regulation and the standards we have researched, the compatibility to the above commands of the entire device created according to the contents of this material, is not guaranteed. The methods to enable a device to conform to the commands and the compatibility must be determined by the manufacturer who produces the machine device.

2.1.2 Installation on the control panel
Installing devices on the control panel has a considerable effect not only in securing safety but also in shutting down the noise generated from the PC by the control panel.
(1) Control panel (a) Use an electrically conductive control panel. (b) When fastening tightening the control panel's top or bottom panel with bolts, mask the
coating so that surface contact is feasible. (c) To ensure the electrical contact between the inside panel of the control panel and the main
control panel, mask any coating around the installation bolts connecting to the main unit to secure conductivity in the largest surface area possible.
(d) Ground the control panel main unit using a thick ground cable so that a low impedance can be secured even with a high frequency.
(e) Make the holes on the control panel less than 10 cm (3.94 in.) in diameter. A hole larger than 10 cm (3.94 in.) may leak electric waves.
(2) Layout of power supply cable and ground cable The layout of power supply cable and ground cable for a PC should be set as described below.
(a) Specify a grounding point that enables grounding of the control panel close to the power supply to the PC and ground the FG (frame ground) terminal of the PC or the SLD (shield) terminal of the I/F board using the thickest, shortest cable possible (about 30 cm (11.81 in.) or less in length). Since the FG and SLD terminals play a role in grounding the noise generated in the PC, it is necessary to ensure the lowest possible impedance. Because the power line is used to allow the noise to escape, it actually contains a great deal of noise. Therefore, shortening the wire length prevents the power line from becoming an antenna.
Note : A long conductive material can become an antenna that emits noise more efficiently.
(b) Twist the ground cable leading to the ground point with the power supply cable. By twisting them with the ground cable, the noise leaking out of the power supply cable may be grounded at a higher rate. However, when a noise filter is installed to the power supply cable, twisting with the ground cable may not be necessary.

2.1.3 Cable
Because the cable that runs from the control panel contains high frequency noise, outside the control panel it acts as an antenna and radiates noise. Always use shielded cable for cable that runs outside the control panel. Except for certain models, using the ferrite core is not mandatory. However, the noise radiated via cable can be suppressed more effectively by mounting a ferrite core. Using a shielded cable is also effective in raising noise resistance. The signal lines used for PLC input/output and special units are designed to ensure a noise resistance level of 2 kV (IEC801- 4/EN61000-4-4) if a shielded cable is used. If a shielded cable is not used, or when a shielded cable is not grounded properly, the noise resistance will drop below 2 kV.
Note : With the EN50082-2, the noise resistance of each signal line is specified based on the application of the signal. Signals related to control (process control) : 2 kV Signals not related to control (process control)) : 1 kV
In the EN50082-2, the meaning of (signals) related to control is not defined. However, considering the original intent of the EMC command, the signal line that poses possible danger to person or equipment when the panel is incorrectly operated shall be defined as the signal related to control, and high noise resistance is considered mandatory.
(1) Grounding treatment for shields (a) Perform shielding processing at a position near the exit of the control panel. If the grounding
point is far from the exit position, the cable portion after the grounding point will cause electromagnetic induction and generates high-frequency noise.
(b) Use a grounding method that allows the shield a surface grounding in a large area against the control panel. A clamping fixture as shown below may alternatively be used. When such a fixture is used, mask the coating in the area inside the control panel where the fixture contacts.

Note : The method shown below in which a PVC electric wire is soldered to the shield of the shielded cable and that end is grounded, increases the high frequency impedance and the effectiveness of the shield is lost.

(2) Grounding treatment for the CC-Link cable (a) Always ground the twisted cable connected to the CC-Link master station, local station and
remote station. Since the twisted cable is a shielded cable, remove part of the outer sheath. Then ground the exposed part of the shield indicated in the figure below as wide a surface area as possible.

All of this area should be grounded. Always use the cable specified for this cable.

Also, ground within 30 cm (11.81.in.) from the board terminal area in addition to grounding at the position closest to the exit of the control panel.
(b) Always use the specified cable for the CC-Link cable.
(c) For each module, do not use a ferrite core for the CC-Link cable from the board.
(d) For each module, ground both the FG terminal and SLD terminal of the board.

2.1.4 Noise filter (power supply line filter)
A noise filter is a part that has a considerable effect in preventing conductive noise. Except for a few models, installation of a noise filter to the power supply line is not mandatory. However, the installation of a noise filter can suppress noise at a higher rate (a noise filter is effective for reducing noise emitted in the range below 10MHz). Use a noise filter equivalent to the models shown below.

Rated voltage 250 V
Precautions when installing a noise filter are noted below.
(1) Do not bundle the wiring on the input and output side of the noise filter. If they are bundled, noise on the output side will be inducted to the wiring on the input side where the noise has been removed by a filter.

(2) Ground the ground terminal for the noise filter to the control panel using as short wiring as possible (about 10 cm (3.94 in.)).
