Regulations and Standards
• EMC Directives
• Low Voltage Directive
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 EC
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 61131-2.
Conformance to EC Directives
The NX-series Units comply with EC Directives. To ensure that the machine or device in which the
NX-series Units are used complies with EC Directives, the following precautions must be observed.
• The NX-series Units must be installed within a control panel.
• You must use reinforced insulation or double insulation for the DC power supplies that are con-
nected as the Unit power supplies and I/O power supplies for the NX-series Units.
We recommend that you use the OMRON S8JX-series Power Supplies. EMC standard compli-
ance was confirmed for the recommended Power Supplies.
• NX-series Units that comply with EC 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 EC 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 power supplies and I/O power supplies for the NX-series
Units.
• 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.
