EMC Directives
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.*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 equip-
ment 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.
*1. Applicable EMC (Electromagnetic Compatibility) standards are as follows: EMS (Electromagnetic Suscept-
ibility): EN 61131-2, EMI (Electromagnetic Interference): EN 61131-2 (Radiated emission: 10-m regula-
tions).
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 NXR-series products comply with EU Directives. To ensure that the machine or device in which
the NXR-series products are used complies with EU Directives, the following precautions must be
observed.
• You must use SELV power supply for the DC power supplies that are connected as the Unit/input
power supplies and output power supplies for the NXR-series products.
We recommend that you use the OMRON S8VK-S-series Power Supplies. EMC standard com-
pliance was confirmed for the recommended Power Supplies.
• NXR-series products that comply with EU Directives also conform to the Common Emission
Standard. Radiated emission characteristics (10-m regulations) may vary depending on the con-
figuration of the control panel used, other devices connected to the control panel, wiring, and oth-
er conditions.
You must therefore confirm that the overall machine or equipment in which the NXR-series prod-
ucts 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 sup-
plies that are connected as the Unit/input power supplies and output power supplies for the NXR-
series products.
