To other loads which
must be protected
against line pollution
caused by converters
(HF disturbance and
commutation notches).
Mounting

Line filter
Line choke
A separation transformer
with grounded screen and
with grounded iron core
makes the line filter and the
line choke unnecessary.
Operation with separate converter
transformer. If there are other loads at the
same secondary winding they have to
withstand the commutation notches,
caused by the converter. In some cases
commutation chokes are necessary (see
1.4).
Operation at the public low
voltage line together with other
loads of all kinds except some
kinds of sensitive communication
means.
