3.3.2 Emission and Immunity Levels

EMC Phenomenon
Emission:
Mains Terminal.
Disturbance Voltage.
Frequency Range: 150 kHz to 30 MHz).
Electromagnetic Radiation Disturbance"
Frequency Range: 30 MHz to 1000 MHz).
Immunity:
Electrostatic Discharge (ESD).
Fast Transient-Burst.
Conducted Radio-Frequency Common
Mode.
Surges.
Radio-Frequency Electromagnetic Field.
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).
