Standard Definitions
IEC/EN 61800-3: “Adjustable Speed Electrical Power Drives Systems”
- Environment:
First Environment: includes domestic premises. It also includes establishments directly connected without
intermediate transformer to a low-voltage power supply network which supplies buildings used for domestic
purposes.
Example: houses, apartments, commercial installations, or offices located in residential buildings.
Second Environment: includes all establishments other than those directly connected to a low-voltage power
supply network which supplies buildings used for domestic purposes.
Example: industrial area, technical area of any building supplied by a dedicated transformer.
- Categories:
Category C1: inverters with a voltage rating less than 1000 V and intended for use in the First Environment.
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 a movable installations, and installed and commissioned by a professional.
Note: a professional is a person or organization familiar with the installation and/or commissioning of inverters,
including the 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).
Class A1: equipment intended for use in the low-voltage power supply network. Restricted distribution
Note: 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.
