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
conform 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 customer’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 stable 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.
