Definition of Standard IEC/EM 61800-3: "Adjustable Speed Electrical Power
Drives Systems"
Environments:
„
First Environment: Environments that include domestic installations, as well as
establishments directly connected without intermediate transformer to a low-voltage
power supply network which supplies buildings used for domestic purposes.
Second Environment: includes all establishments other than those directly connected to
a low-voltage power supply network that supplies buildings used for domestic purposes.
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 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).
