Regulations and Standards
• EMC Directives
• Low Voltage Directive
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 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.
*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
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 power
supplies and I/O power supplies for the NX-series Units. EMC standard compliance was con-
firmed for the OMRON S8VK-S series DC Power Supplies.
• NX-series Units that comply with EU Directives also conform to the Common Emission Standard.
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.
• This is a Class A product (for industrial environments). In a residential environment, it may cause
radio interference. If radio interference occurs, the user may be required to take appropriate mea-
sures.
