If more than one voltage is specified on the data plate, the tumble

dryer can be converted for connection to the relevant input voltage.
This conversion must be performed by Miele Customer Service or by
an authorized dealer. During the conversion, the wiring instructions
given on the wiring diagram must be followed.
The tumble dryer can either be hard-wired or connected using a plug-
and-socket connection in accordance with IEC 60309-1. For a hard-
wired connection, an all-pole disconnect switch must be available at
the installation site.
A disconnect switch is a switch which ensures a contact opening of
more than 1/8" (3 mm). These include circuit breakers, breakers, and
contactors (IEC/EN 60947).
If the power supply cannot be permanently disconnected, the discon-
nect switch (including plug and socket) must be safeguarded against
being switched on either unintentionally or without authorization.
Tip: We recommend connecting the tumble dryer to the power supply
via a plug and socket so that it is easier to conduct electrical safety
checks (e.g., during maintenance or repair work).
The tumble dryer must not be connected to devices such as timers

which would switch it off automatically.
Limitations to dryer operation due to reconnecting/removing
jumpers.
Modifying/removing jumpers at the heater elements in order to set
lower heater ratings may result in limitations to dryer operation. De-
pending on the type of laundry, length of vent ducting, and outside
temperature, the desired drying results may no longer be achieved.
In the event of a reduction, the specified consumption data will no
longer be achieved.
If it is necessary to install a residual current device (RCD) in accor-

dance with local regulations, a residual current device type B (sensi-
tive to universal current) must be used.
After installing the tumble dryer, equipotential bonding must be es-

tablished. The equipotential bonding must comply with the local and
national installation specifications.
