Regulations and Standards

Conformance to EU Directives

Applicable Directives
• EMC Directives
• Low Voltage Directive
Concepts
 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 NX-series Units comply with EU Directives. To ensure that the machine or device in which the
NX-series Units are used complies with EU Directives, the following precautions must be observed.
• The NX-series Units must be installed within a control panel.
• You must use SELV power supply for the DC power supplies that are connected as the Unit pow-
er supplies and I/O power supplies for the NX-series Units.
EMC standard compliance was confirmed for the recommended Power Supplies. Refer to the us-
er's manual for the connected CPU Unit for information on the recommended Power Supplies for
the CPU Rack of the NX-series CPU Unit. If your High-speed Analog Input Unit is connected to a
Slave Terminal, we recommend that you use the OMRON S8VK-S-series 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.
