Regulations and Standards
• EMC Directive
 EMC Directive
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.*
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.
* Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN 61131-2:2007
EMI (Electromagnetic Interference): EN 61131-2:2007
 Conformance to EU Directives
The NA-series PTs comply with EU Directives. To ensure that the machine or device in which the
NA-series PT is used complies with EU Directives, the NA-series PT must be installed as follows:
• The NA Unit must be installed in a control panel.
• You must use reinforced insulation or double insulation for the DC power supplies connected to
the NA Unit.
• NA-series PTs that comply with EU Directives also conform to the Common Emission Standard
(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, wiring, and
other conditions.
You must therefore confirm that the overall machine or equipment complies with EU Directives.
• This is a Class A product (for industrial environments). In a residential environment, it may cause
radio interference, in which case the user may be required to take appropriate measures.
