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:
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 rated voltage below 1000 V and intended for use in the First
Environment.
Category C2: inverters with a rated voltage below 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 rated voltage below 1000 V and intended for use in the Second
Environment only (not designed for use in the First Environment).

Basic Standard
IEC/EN61800-3 It depends on the inverter model and on the length of
the motor cable. Refer to
IEC 61000-4-4 2 kV / 5 kHz (coupling capacitor) input cables
1 kV / 5 kHz control cables and remote HMIR cables
2 kV / 5 kHz (coupling capacitor) motor cables
IEC 61000-4-6 0.15 to 80 MHz; 10 V; 80 % AM (1 kHz)
Motor, control and HMIR cables
IEC 61000-4-5 1.2/50 μs, 8/20 μs
