than European Union (EU) when local power supply system is the grounded network.
• N-level: Manufacturer’s EMC solution is adopted to fit for Second Environment and products will be
used in EU when local power supply system is the grounded network.

market areas when local power supply system is the non-grounded network.

second environment.

for the second environment.

The involved products are designed for Second Environment (Industrial Environment) only.
The disturbances emitting from the basic products are not filtered to the required level of
residential, commercial and light industrial (e.g. offices, gasoline station, retailer shops etc.)
environment (First Environment). In this sense, these products should not be used in First
environments. If you still want to use them in First environments, additional requirements
are needed, please contact product supplier.
