Product Overview
•
Use star washers and galvanically conductive
installation plates.
2.6.2 Emission Requirements
According to the EMC product standard for adjustable speed drives EN/IEC 61800-3:2004, the EMC requirements depend on
the intended use of the drive. The EMC product standard defines 4 categories, described in Table 2.2, along with the
requirements for mains supply voltage conducted emissions.
Category Definition according to EN/IEC 61800-3:2004
C1
Drives installed in the 1
less than 1000 V.
C2
Drives installed in the 1
less than 1000 V, which are not plug-in or movable, and which are intended for
professional installation and commissioning.
C3
Drives installed in the 2
than 1000 V.
C4
Drives installed in the 2
1000 V, or rated current equal to or above 400 A, or intended for use in
complex systems.
Table 2.2 Emission Requirements - EN/IEC 61800-3:2004
When the generic emission standards are used, the drive must comply with the following limits:
Environment
First environment
(home and office)
Second environment
(industrial environment)

A system comprises VLT DriveMotor FCP 106, motor, and
shielded motor cable.
For this system, the conducted emission complies with EN
55011 Class B, and the radiated emission complies with EN
55011 Class A, Group 1. Compliance is achieved based on
the following conditions:
•
Built-in RFI filter.
•
Drive set to nominal switching frequency.
•
Maximum shielded motor cable length of 2 m
(6.56 ft).
2.6.3 Immunity Requirements
The immunity requirements for drives depend on the
environment in which they are installed. The requirements
for the industrial environment are higher than the
requirements for the home and office environment. All
Danfoss drives comply with the requirements for the

with the lower requirements for home and office
environment with a large safety margin.
To document immunity against burst transient from
electrical phenomena, the following immunity tests have
been carried in accordance with the 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 field radiation, amplitude modulated
simulation of the effects of radar and radio
communication equipment, as well as mobile
communications equipment.
•
EN 61000-4-4 (IEC 61000-4-4): Burst transients:
Simulation of interference brought about by
switching a contactor, relay, or similar devices.
