Conformance to EC Directives
This product is EMC compliant.
● Concepts
OMRON products are electronic devices that are incorporated in machines and manufac-
turing installations. OMRON PTs conform to the related EMC Directives (see note) so that
the devices and machines into which they are built can more easily conform to EMC direc-
tives. However, customers may use a wide variety of equipment and manufacturing instal-
lations. Therefore the customer must check whether the Directives are satisfied for the
actual system. EMC-related performance will vary depending on the configuration, wiring,
and other conditions of the equipment or control panel in which the PT is installed. The
customer must, therefore, perform final checks to confirm that the overall machine or
device conforms to EMC standards.
● Conformance to EC Directives
NV-series PTs conform to EC Directives. To ensure that the machine or device in which
the NV-series PT is used complies with EC Directives, the PT must be installed as follows:
• The NV-series PT must be installed in a control panel.
• You must use reinforced insulation or double insulation for the DC power supply and
• NV-series PTs complying with EC Directives also conform to the Common Emission
• This is a class A product. It may cause radio interference in residential areas, in which

Note The applicable EMC (Electromagnetic Compatibility) standards for NV-series
PTs are as follows:
NV3W: EN 61000-6-2, EN 61000-6-4
NV4W/NV3Q: EN 61131-2
the DC power supply must have minimal voltage fluctuations and provide a stable out-
