CHAPTER 3 - INSTALLATION AND CONNECTION
EMC phenomenon
Emission:
Conducted emissions (mains
terminal disturbance voltage - freq
band 150 kHz to 30 MHz)
Radiated emissions (electromagnetic
radiation disturbance - freq band
30 MHz to 1000 MHz)
Immunity:
Electrostatic discharge (ESD)
Fast Transient-Burst
Conducted radio-frequency
common mode
Surge
Radio-frequency electromagnetic field

3.3.2 Specification of the
Emission and Immunity
Levels
Notes:
(1) "First environment": environment that includes domestic
premises. It also includes establishments directly connected
without intermediate transformers to a low-voltage power supply
network which supplies buildings used for domestic purposes.
(2) "Second environment": environment that includes all establishments
other than those directly connected to a low-voltage power supply
network which supplies buildings used for industrial purposes.
(3) Unrestricted distribution: mode of sales distribution in which the
supply of equipment is not dependent on the EMC competence
of the customer or user for the application of drives.
(4) Restricted distribution: mode of sales distribution in which the
manufacturer restricts the supply of equipment to suppliers,
customers or users who separately or jointly have technical
competence in the EMC requirements of the application of drives.
