The essential correlation between the two standards is illustrated as follows:
Category according to product standard
EN 61800-3 C1 C2 C3
Limit value class according to EN 55011 B A1 A2
Operation permissible in
1st environment (domestic environment) X X -
2nd environment (industrial environment) X X X
Information required according to
EN 61800-3 - 1) 2)
Distribution method Generally available Limited availability
EMC knowledge No requirements Installation and commissioning by persons with
knowledge of EMC
1) "In a domestic environment, the drive system may cause high frequency interference, which may make interference suppression measures necessary."
2) "The drive system is not intended for use in a public low voltage mains network which supplies the domestic area."
9.3.3 EMC of the frequency inverter
ATTENTION
The frequency inverters are exclusively intended for commercial use. They are therefore
not subject to the requirements of the standard EN 61000-3-2 for radiation of harmonics.
This device produces high frequency interference, which may make additional suppression
measures necessary in domestic environments.
Please note that these limit value classes are only reached if the standard pulse frequency (6kHz) is being
used and the length of the shielded motor cable does not exceed the permissible limits.
In addition, it is essential to use wiring suitable for EMC. For wall mounting, the screening of the motor cable
must be connected to both the motor terminal box and the housing of the inverter.
