4-3 Mounting Units
The Units that make up an NJ-series Controller can be connected simply by pressing the Units together
and locking the sliders by moving them toward the back of the Units. The End Cover is connected in 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 Precautions
15
NXR-series IO-Link Master Unit for EtherCAT User’s Manual (W640)

Warnings
WARNING
During Power Supply
Do not touch the terminal section while power is ON.
Electric shock may occur.
Do not attempt to take any Unit apart.
In particular, high-voltage parts are present in Units that supply power while power is
supplied or immediately after power is turned OFF. Touching any of these parts may re-
sult in electric shock. There are sharp parts inside the Unit that may cause injury.
Fail-safe Measures
Provide safety measures in external circuits to ensure safety in the system if an abnor-
mality occurs due to malfunction of the CPU Unit, other Units, or slaves or due to other
external factors affecting operation.
Not doing so may result in serious accidents due to incorrect operation.
Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures
must be provided in external control circuits.
The outputs may remain ON or OFF due to deposition or burning of the output relays or
destruction of the output transistors. As a countermeasure for such problems, external
safety measures must be provided to ensure safe operation of the system.
The CPU Unit will turn OFF all outputs from Basic Output Units in the following cases.
The remote I/O slaves will operate according to the settings in the slaves.
• If a power supply error occurs.
•If the power supply connection becomes faulty.
• If a CPU watchdog timer error or CPU reset occurs.
• If a Controller error in the major fault level occurs.
• While the CPU Unit is on standby until RUN mode is entered after the power is turned
ON
External safety measures must be provided to ensure safe operation of the system in
such cases.
You must take fail-safe measures to ensure safety in the event of incorrect, missing, or
abnormal signals caused by broken signal lines, momentary power interruptions, or oth-
er causes.
Not doing so may result in serious accidents due to incorrect operation.
Voltage and Current Inputs
Make sure that the voltages and currents that are input to the Units and slaves are within
the specified ranges.
Inputting voltages or currents that are outside of the specified ranges may cause acci-
dents or fire.
Safety Precautions
16 NXR-series IO-Link Master Unit for EtherCAT User’s Manual (W640)

Power Supply Design
Follow the instructions in this manual to correctly perform power supply design and wir-
ing. Inputting voltages or currents that are outside of the specified ranges, as well as in-
correct wiring, may cause failure or fire.
Wiring
Make sure that the grounds (0 V) of the Unit/input power supply and the output power
supply are at the same potential.
Transferring
Always confirm safety at the destination node before you transfer Unit configuration in-
formation, parameters, settings, or other data from tools such as the Sysmac Studio.
The devices or machines may operate unexpectedly, regardless of the operating mode
of the Controller.
Security Measures
Anti-virus protection
Install the latest commercial-quality antivirus software on the computer connected to
the control system and maintain to keep the software up-to-date.
Security measures to prevent unauthorized access
Take the following measures to prevent unauthorized access to our products.
•Install physical controls so that only authorized personnel can access control sys-
tems and equipment.
• Reduce connections to control systems and equipment via networks to prevent ac-
cess from untrusted devices.
• Install firewalls to shut down unused communications ports and limit communica-
tions hosts and isolate control systems and equipment from the IT network.
• Use a virtual private network (VPN) for remote access to control systems and equip-
ment.
• Adopt multifactor authentication to devices with remote access to control systems
and equipment.
• Set strong passwords and change them frequently.
• Scan virus to ensure safety of USB drives or other external storages before connect-
ing them to control systems and equipment.
Data input and output protection
Validate backups and ranges to cope with unintentional modification of input/output da-
ta to control systems and equipment.
•Checking the scope of data
• Checking validity of backups and preparing data for restore in case of falsification
and abnormalities
• Safety design, such as emergency shutdown and fail-soft operation in case of data
tampering and abnormalities

NXR-series IO-Link Master Unit for EtherCAT User’s Manual (W640)

Data recovery
Backup data and keep the data up-to-date periodically to prepare for data loss.
When using an intranet environment through a global address, connecting to a SCADA
or an unauthorized terminal such as an HMI or to an unauthorized server may result in
network security issues such as spoofing and tampering. You must take sufficient
measures such as restricting access to the terminal, using a terminal equipped with a
secure function, and locking the installation area by yourself.
When constructing an intranet, communication failure may occur due to cable discon-
nection or the influence of unauthorized network equipment. Take adequate measures,
such as restricting physical access to network devices, by means such as locking the
installation area.
When using a device equipped with the SD Memory Card function, there is a security
risk that a third party may acquire, alter, or replace the files and data in the removable
media by removing the removable media or unmounting the removable media. Please
take sufficient measures, such as restricting physical access to the Controller or taking
appropriate management measures for removable media, by means of locking the in-
stallation area, entrance management, etc., by yourself.
