The Units that make up an NJ-series Controller canbe connectedsimply bypressingtheUnits together
and locking the sliders by moving them toward the back of the Units. The End Cover is connectedin the
same way to the Unit on the far right side of the Controller.
1Join the Units so that the connectors fit exactly.
2The yellow sliders at the top and bottom of each Unit lock the Units together. Move the sliders
toward the back of the Units as shown below until they click into place.

Safety Precaution
Refer to the following manuals for safety precautions.
• NJ-series CPU Unit Hardware User’s Manual (Cat. No. W500)
• Sysmac Studio Version 1 Operation Manual (Cat. No. W504)

Precautions for Safe Use
NJ-series CPU Unit OPC UA User’s Manual (W588)
Precautions for Safe Use
This section describes the precautions for the safe use of the OPC UA Server.
• Even if you accidentally add the client certificate of a client for which you do not want to permit con-
nection in the Trusted Certificate List, the OPC UA Server of the NJ-series Controller will permit con-
nections from that client.
As a result, confidential information on the server side may be leaked or unintended operation may
be performed. Therefore, when you add a certificate to the Trusted Certificate List from the Sysmac
Studio, make sure that all the certificates that you will register in the Trusted Certificate List are
trusted client certificates.
• Even if a global variable is set to Network Publish in the Sysmac Studio, the OPC UA client may not
be able to refer to or read/write the variable in some cases depending on the limits sets on variables
that can be published to the OPC UA client.
Refer to the event log or Execution Log, and review the variables to be published to the network
depending on the cause of occurrence. For details on the restrictions on variables that can be pub-
lished in the OPC UA client, refer to Restrictions on Publishing to the OPC UA Client on page 6-7 in
6-2-2 Reading/Writing the Variables of the CPU Unit on page 6-5.
Refer to the following manuals for other precautions for safe use that are not described above.
• NJ-series CPU Unit Hardware User’s Manual (Cat. No. W500)
• Sysmac Studio Version 1 Operation Manual (Cat. No. W504)

Precautions for Correct Use
14 NJ-series CPU Unit OPC UA User’s Manual (W588)
Precautions for Correct Use
This section describes the precautions for the correct use of the OPC UA Server.
• If the IP address of the built-in EtherNet/IP port is changed after starting the use of the OPC UA
Server, the OPC UA server certificate in the CPU Unit will be disabled, and it will not be possible to
communicate with the OPC UA client. In that case, manually regenerate the server certificate, or set
the IP address back to the original address.
• The server certificate is not applied for backup and restore because it is information belonging to indi-
vidual CPU Units. If you replace the CPU Unit hardware, you cannot use the same server certificate
for the new CPU Unit after the replacement.
Even if you set the IP address of the built-in EtherNet IP port to the same value as the one for the
previous CPU Unit, be sure to export the server certificate of the new CPU Unit and then perform
installation again on the OPC UA clients.
• Even in cases where you recreate the server certificate by changing the IP address in the same CPU
Unit, make sure to export the server certificate of the CPU Unit and install it at the OPC UA client
side.
• The OPC UA Server is executed as a system service.
Accordingly, if other system services are executed while the OPC UA Server is starting up, they may
take longer.
Moreover, if the system service execution time ratio is less (if it is below approx. 20%, as a refer-
ence), the response to the requests from the OPC UA client will be delayed. In such a case, design
the task so that the system service execution time ratio increases.
Refer to the following manuals for other precautions for correct use that are not described above.

• Sysmac Studio Version 1 Operation Manual (W504)

Regulations and Standards
NJ-series CPU Unit OPC UA User’s Manual (W588)
Regulations and Standards
• EMC Directives
• Low Voltage Directive
zEMC Directive
OMRON devices that comply with EU Directives also conform to the related EMC standards so that
they can be more easily built into other devices or the overall machine. The actual products have
been checked for conformity to EMC standards.*
Whether the products conform to the standards in the system used by the customer, however, must
be checked by the customer. EMC-related performance of the OMRON devices that comply with EU
Directives will vary depending on the configuration, wiring, and other conditions of the equipment or
control panel on which the OMRON devices are installed. The customer must, therefore, perform
the final check to confirm that devices and the overall machine conform to EMC standards.
* Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN 61131-2
EMI (Electromagnetic Interference): EN 61131-2(Radiated emission: 10-m regulations)
zLow Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 VAC and 75 to 1,500 VDC meet the
required safety standards. The applicable directive is EN 61010-2-201.
zConformance to EU Directives
The NJ/NX-series Controllers comply with EU Directives. To ensure that the machine or device in
which the NJ/NX-series Controller is used complies with EU Directives, the Controller must be
installed as follows:
• The NJ/NX-series Controller must be installed within a control panel.
• You must use the power supply in SELV specifications for the DC power supplies connected to
DC Power Supply Units and I/O Units.
• NJ/NX-series Controllers that comply with EU Directives also conform to the Common Emission
Standard (EN 61000-6-4). Radiated emission characteristics (10-m regulations) may vary
depending on the configuration of the control panel used, other devices connected to the control
panel, wiring, and other conditions.
You must therefore confirm that the overall machine or equipment complies with EU Directives.

Observe the following precaution if you use NX-series Units in Korea.
Class A Device (Broadcasting Communications Device for Office Use)
This device obtained EMC registration for office use (Class A), and it is intended to be used in places
other than homes.
Sellers and/or users need to take note of this.
The NJ-series Controllers comply with the following shipbuilding standards. Applicability to the ship-
building standards is based on certain usage conditions. It may not be possible to use the product in
some locations. Contact your OMRON representative before attempting to use a Controller on a ship.
• The NJ-series Controller must be installed within a control panel.
• Gaps in the door to the control panel must be completely filled or covered with gaskets or other
material.
• The following noise filter must be connected to the power supply line.

Versions
Hardware revisions and unit versions are used to manage the hardware and software in the NJ-series
Units and EtherCAT slaves. The hardware revision or unit version is updated each time there is a
change in hardware or software specifications. Even when two Units or EtherCAT slaves have the
same model number, they will have functional or performance differences if they have different hard-
ware revisions or unit versions.
You can check versions on the ID information indications or with the Sysmac Studio.
The unit version is given on the ID information indication on the side of the product.
