Lenze i550-C0.25/120-1 - RFI Filters; Mains Filters

RFI lters / Mains lters
RFI and mains lters are used to ensure compliance with the EMC requirements of European
Standard EN 61800-3. This standard denes the EMC requirements for electrical drive system
in various categories.
•
RFI lters are capacive accessory components. RFI lters reduce conducted noise emis-
sions. RFI lters are also called EMC lters.
•
Mains lters are a combinaon of mains choke and RFI lter. Mains lters reduce the con-
ducted noise emission.
Denion of the environments
(EN 61800−3)
First environment
The rst environment comprises residenal buildings or locaons that are directly connected
to a low-voltage system for supplying residenal areas.
Second environment
The second environment comprises facilies or locaons that are not directly connected to a
low-voltage system for supplying residenal areas.
Category C1
Category C1 denes the requirements for drive systems that are intended for the use in the
rst environment at a rated voltage lower than 1000 V.
The limit values of the EN 61800−3 comply with EN 55011 class B.
Category C2
Category C2 denes the requirements for permanently installed drive systems that are inten-
ded for the use in the rst environment at a rated voltage lower than 1000 V. Installaon and
commissioning must only be carried out by qualied personnel with EMC knowledge.
The limit values of the EN 61800−3 comply with EN 55011 class A group 1.
Category C3
Category C3 denes the requirements for drive systems that are exclusively intended for the
use in the second environment at a rated voltage lower than 1000 V.
The limit values of the EN 61800−3 comply with EN 55011 class A group 2.
When working with stricter line-bound noise emission requirements which can-
not be met using the radio interference suppression measures integrated in the
inverter, external lters can be used. The lters can be installed below or next to
the inverter.
If necessary, the internal lters have to be deacvated when external lters are
used. For this purpose, remove the IT screws of the inverters.
