Safety Precautions
WARNING
Warnings
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 result 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 abnormality
occurs due to malfunction of the CPU Unit, Industrial PC, 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 CPU Unit or Industrial PC will turn OFF all outputs from 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.
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.
If external power supplies for slaves or other devices are overloaded or short-circuited, the
voltage will drop, outputs will turn OFF, and the system may be unable to read inputs. Provide external safety measures in control with monitoring of external power supply voltage
as required so that the system operates safely in such a case.
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 other
causes.
Not doing so may result in serious accidents due to incorrect operation.

NX-series IO-Link Master Unit User’s Manual (W567)
Voltage and Current Inputs
Caution
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 accidents
or fire.
Transferring
Always confirm safety at the destination node before you transfer Unit configuration information, 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.
Cautions
Safety Precautions
Wiring
When you connect a computer or other peripheral device to a Communications Coupler
Unit that has a non-isolated DC power supply, either ground the 0-V side of the external
power supply (i.e. Unit power supply) or do not ground it at all.
If the peripheral devices are grounded incorrectly, the external power supply (i.e. Unit
power supply) may be short-circuited.
Never ground the 24-V side of the power supply, as shown in the following figure.

Precautions for Safe Use
Turning ON the Power Supply
• When you set the Operating Mode at Startup, confirm that no adverse effect will occur in the system.
Actual Operation
• Before you start operation, always register the NX Units that are connected to the Communications
Coupler Unit in the host communications master as the Unit Configuration Information.
• Check the user program, data, and parameter settings for proper execution before you use them for
actual operation.
• If you change the fail-soft operation setting, the output status when the error occurs may also change.
Confirm safety before you change the fail-soft operation setting.
• If you use fail-soft operation, write programming to determine whether Unit I/O data is valid. Without
such programming, the user program cannot distinguish between Units for which I/O refreshing is
continued and Units for which I/O refreshing is stopped.
Turning OFF the Power Supply
• Do not disconnect the cable or turn OFF the power supply to the Controller or a Slave Terminal when
downloading data or the user program from Support Software.
• Always turn OFF the external power supply to the Units before attempting any of the following.
Mounting or removing an NX Unit, Communications Coupler Unit, CPU Unit, or Industrial PC
Assembling Units
Setting DIP switches or rotary switches
Connecting or wiring cables
Attaching or removing terminal blocks or connectors
Units that supply power continue to supply power to the Units for up to several seconds after the
power supply is turned OFF. The PWR indicator remains lit as long as power is supplied. Confirm that
the PWR indicator is not lit before you perform any of the above.
Operation
• Confirm that the controlled system will not be adversely affected before you perform any of the following operations.
Changing the operating mode of the CPU Unit or Industrial PC (including changing the setting of the
Operating Mode at Startup)
Changing the user program or settings
Changing set values or present values
Forced refreshing
• Always sufficiently check the safety at the connected devices before you change the settings of a
slave or Unit.
20
General Communications
• Do not exceed the ranges that are given in the specifications for the communications distance and
number of connected Units.
• Refer to the user’s manual for the Communications Coupler Unit for precautions for the safe use of
communications with the connected Communications Coupler Unit.
NX-series IO-Link Master Unit User’s Manual (W567)
Precautions for Safe Use
Unit Replacement
• When you replace a Unit, start operation only after you transfer the settings and variables that are
required for operation to the new Unit.
• Default values of I/O allocation differ between the IO-Link Master Unit with unit version 1.0 and one
with unit version 1.1.
If you replace a Unit with unit version 1.0 with a Unit with unit version 1.1 or later, set the I/O allocation to the same setting as the Unit with unit version 1.0. Replacing the Unit without changing the I/O
allocation may result in erroneous output, erroneous input, and a change in the timing of I/O.

Applicable Directives
• EMC Directives
• Low Voltage Directive
Concepts
EMC Directives
OMRON devices that comply with EC 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.*1
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.
Regulations and Standards
*1. 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).
Low 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.
Conformance to EU Directives
The NX-series Units comply with EU Directives. To ensure that the machine or device in which the

• The NX-series Units must be installed within a control panel.
• The SELV requirements must be satisfied for the DC power supplies that are connected as the
Unit power supplies and I/O power supplies for the NX-series Units.
For CPU Racks with NX-series NX1P2 CPU Units, we recommend that you use OMRON
S8VK-S-series Power Supplies. For Slave Terminals, we recommend that you use OMRON
S8JX-series Power Supplies. EMC standard compliance was confirmed for these recommended
Power Supplies.
• NX-series Units that comply with EU Directives also conform to the Common Emission Standard
(EN 61131-2). 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 in which the NX-series Units
are used complies with EU Directives.
• You must use power supplies with an output hold time of 10 ms or longer for the DC power supplies that are connected as the Unit power supplies and I/O power supplies for the NX-series
