Emission And Immunity Levels - WEG CFW-11 Series User Manual

Installation and Connection
Category C2: inverters with a voltage rating less than 1000 V intended for use in the First Environment,
not provided with a plug connector or movable installations. They must be installed and commissioned by a
professional.
Note: A professional is a person or organization familiar with the installation and/or commissioning of inverters,
including their EMC aspects.
Category C3: inverters with a voltage rating less than 1000 V and intended for use in the Second Environment
only (not designed for use in the First Environment).
Category C4: inverters with a voltage rating equal to or greater than 1000 V, or with a current rating equal to
or greater than 400 Amps, or intended for use in complex systems in the Second Environment.
EN 55011: "Threshold values and measuring methods for radio interference from industrial, scientific
and medical (ISM) high-frequency equipment"
Class B: equipment intended for use in the low voltage power supply network (residential, commercial, and
light industrial environments).
3
Class A1: equipment intended for use in the low voltage power supply network. Restricted distribution.
Note: It must be installed and commissioned by a professional when applied in the low voltage power supply
network.
Class A2: equipment intended for use in industrial environments.
