Mains filter
A mains filter is a combination of mains choke and RFI filter
in one housing. Mains filters offer the same advantages as
mains chokes. In addition, they enable compliance with the
interference voltage categories of the European standard EN
61800-3. There a distinction is drawn between category C1
and category C2.
Category C1
describes the use on public supply networks.
Category C2
describes the use of drives which are intended
for industrial purposes in areas also comprising residential
areas.
Mains filters A and B
For the 9300 servo inverters, the components mains filter A,
mains filter B and mains filter are available for compliance
with the interference voltage categories.
In addition to reducing the line-bound noise emission into
the mains network, a mains filter replaces the function of a

The filters are designed as side-by-side-mounted and
footprint filters.
The mains filters are available in the power range from 15 to
75 kW.

When mounting the servo inverter according to the "push-
through technique" or "cold plate" technology, only foot-
print mains filters can be used for interference suppres-
sion.

They have an adapted connecting cable and must be
mounted in the direct proximity of the inverter to ensure
compliance with the limit values.
