FRITSCH PULVERISETTE 5/4 classic line - Manual (Page 24)

The mains voltage has been set at the factory to that of the
specific country. The mains voltage only has to be adjusted
if it deviates from the value on the type plate. If adjustment
is necessary, proceed as in Ä Chapter 4.5.1.1 ‘Adjusting the
mains voltage with the rotary switch (8)’ on page 24 and
Ä Chapter 4.5.1.2 ‘Adjusting the mains voltage in setup
mode’ on page 25.
NOTICE!
Fritsch mills are speed controlled. The devices are equipped
for this with frequency converters. In order to comply with
the EMC directive, many measures must be taken to pre-
vent operational transient emissions.
The possible leakage currents resulting from filtering meas-
ures can trigger a conventional residual current circuit
breaker in the mains line. This is no defect!
To prevent this, special residual current circuit breakers,
which are adapted for operation with frequency converters,
are commercially available.
Operation without a residual current switch is possible, but
must be done in accordance with the relevant regulations.

The voltage range may only be adjusted after the mains has
been disconnected.
