Regulations and Standards
• EMC Directives
• Low Voltage Directive
EMC Directive
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.*
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.
* 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 NJ-series Controllers comply with EU Directives. To ensure that the machine or device in which
the NJ-series Controller is used complies with EU Directives, the Controller must be installed as fol-
lows:
• The NJ-series Controller must be installed within a control panel.
• You must use the power supply in SELV specifications for the DC power supplies connected to
DC Power Supply Units and I/O Units.
• NJ-series Controllers that comply with EU Directives also conform to the Common Emission Stan-
dard (EN 61000-6-4). Radiated emission characteristics (10-m regulations) may vary depending
on the configuration of the control panel used, other devices connected to the control panel, wir-
ing, and other conditions.
You must therefore confirm that the overall machine or equipment complies with EU Directives.
