NB-series Programmable Terminals Startup Guide Manual(V109)
Conformance to EC Directives
NB-Series Programmable Terminals are EMC compliant.
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. The actual products
have been through inspections and are completely in accordance with EMC directives. However, when
they are built into customers’ systems, whether the systems also comply with these Directives is up to
the customers for further inspection.
EMC-related performance of OMRON PTs will vary depending on the configuration, wiring, and other
conditions of the OMRON equipment or control panel. The customer must, therefore, perform final
checks to confirm that the overall machine or device conforms to EMC standards.
Note The applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic sensitivity): EN61131-2: 2007
EMI (Electromagnetic Interference): EN61131-2: 2007
NB-Series Programmable Terminals are EC compliant. Heed the following precautions in order to
ensure that the customer’s overall machine and device conform to EC Directives.
1
The PT must be installed in a control panel.
2
You must use reinforced insulation or double insulation for the DC power supply and the DC
power supply must have minimal voltage fluctuations and provide a stable output even if the
power supply input is interrupted for 10 ms.
3
The PTs conform to the standard EN 61131-2, but radiated emission characteristics (10m
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 EC Directives.
4
This is a Class A product (Product for industry purpose). It may cause radio interference in
residential areas, in which case the user may be required to take adequate measures to reduce
interference.
Observe the following precaution if you use NB-series Programmable Terminals in Korea.
Class A Device (Broadcasting Communications Device for Office Use)
This device obtained EMC registration for office use (Class A), and it is intended to be used in
places other than homes.
Sellers and/or users need to take note of this.
