Danfoss VLT AQUA Drive FC 202 Design Guide

3.2.3 Emission Requirements
The EMC product standard for adjustable frequency drives
denes four categories (C1, C2, C3 and C4) with specied
requirements for emission and immunity. Table 3.5 states
the denition of the four categories and the equivalent
classication from EN 55011.
Category Denition
Equivalent
emission class
in EN 55011
C1 Adjustable frequency drives
installed in the rst environment
(home and oce) with a supply
voltage less than 1000 V.
Class B
C2 Adjustable frequency drives
installed in the rst environment
(home and oce) with a supply
voltage less than 1000 V, which are
neither plug-in nor movable and
are intended to be installed and
commissioned by a professional.
Class A Group 1
C3 Adjustable frequency drives
installed in the second
environment (industrial) with a
supply voltage lower than 1000 V.
Class A Group 2
C4 Adjustable frequency drives
installed in the second
environment with a supply voltage
equal to or above 1000 V or rated
current equal to or above 400 A or
intended for use in complex
systems.
No limit line.

When the generic (conducted) emission standards are
used, the adjustable frequency drives are required to
comply with the limits in Table 3.6.

Immunity Requirements
The immunity requirements for adjustable frequency drives
depend on the environment where they are installed. The
requirements for the industrial environment are higher
than the requirements for the home and oce
environment. All Danfoss adjustable frequency drives
comply with the requirements for the industrial
environment and consequently comply also with the lower
requirements for home and oce environment with a
large safety margin.
To document immunity against electrical interference, the
following immunity tests have been made in accordance
with following basic standards:
•
EN 61000-4-2 (IEC 61000-4-2): Electrostatic
discharges (ESD): Simulation of electrostatic
discharges from human beings.
•
EN 61000-4-3 (IEC 61000-4-3): Incoming electro-
magnetic
eld radiation, amplitude modulated
simulation of the eects of radar and radio
communication equipment as well as mobile
communications equipment.
•
EN 61000-4-4 (IEC 61000-4-4): Electrical
interference: Simulation of interference brought
about by switching a contactor, relay or similar
devices.
•
EN 61000-4-5 (IEC 61000-4-5): Surge transients:
Simulation of transients brought about, for
example, by lightning that strikes near instal-
lations.
•
EN 61000-4-6 (IEC 61000-4-6): RF Common
mode: Simulation of the
eect from radio-
transmission equipment joined by connection
cables.
