Omron NS - REV 12 Setup Manual page 17

Conformance to
This product is EMC compliant.
• Concepts
OMRON products are electronic devices that are incorporated in machines and manufacturing
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 directives.
However, customers may use a wide variety of equipment and manufacturing installations.
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.
Note: Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN 61131-2
EMI (Electromagnetic Interference): EN 61131-2
(EN 61131-2 radiated emission: 10-m regulations)
• Conformance to EC Directives
NS-series PTs conform to EC Directives. To ensure that the machine or device in which the
NS-series PT is used complies with EC Directives, the PT must be installed as follows:
• The NS-series PT must be installed in a control panel.
• You must use reinforced insulation or double insulation for the DC power supply and the
• NS-series PTs complying with EC Directives also conform to the Common Emission
