Conforming Directive
The NP-series PTs conform to the EMC Directive.
EMC Directive Conformance
OMRON products are designed as electrical devices for use built into other devices or the overall
machine. As individual devices, they comply with the related EMC standards (see note) so that they
can more easily be built into other devices or the overall machine. The actual products have been
checked for conformity to EMC standards. Whether they 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 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 con-
form to EMC standards.
Note 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)
Complying with EC Directives
NP-series PTs comply with EC Directives. Observe the following precautions to ensure that the cus-
tomer's device and the overall machine also comply with EC Directives.
1. The PT is designed for installation inside a control panel. The PT must be installed within a control
panel.
2. Use reinforced insulation or double insulation for the DC power supply to the PT. Ensure that a sta-
ble power output can be provided even if a 10-ms interruption occurs at the input.
3. The PT conforms to the EN 61131-2, but the 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 EC Directives.
4. The NP-series PTs are Class A products. It may cause radio interference in residential areas, in
which case the user may be required to take adequate measures to reduce interference.
