Connection to the power supply – notes for the installer
WARNING
Electric shock / fi re hazard!
Improperly installed electrical connec-
tions can cause electrical shocks and/or
short circuits.
■ Connection to the mains supply may
only be made by an authorised elec-
trician approved by the local energy
supply company, e.g. our service cen-
tre (see page EN-38). Only then will
you benefi t from our warranty and a
suffi cient level of safety.
■ Since all poles of the appliance can-
not be disconnected from the mains
via an accessible disconnecting de-
vice, an all-pole disconnecting device
in accordance with overvoltage cat-
egory III must be connected within
the house installation with at least 3
mm contact clearance; this includes
fuses, miniature circuit breakers and
protective devices.
Connection conditions
– The rated voltages allowed as well as the
rating of the device can be found in Chapter
„Technical specifications“ on page EN-43.
– Depending on the type of connection al-
lowed, you must
– select the cross-section cable
– insert or remove contact bridges (see
table and circuit diagrams on the right).
– The power cord used must comply with
the requirements of DIN EN 60335-1 (e.g.
H05RR-F model).
– A separate power supply is required.
– When connecting the appliance, VDE re-
quirements and the “Technical connection
requirements” must be observed.
Contact protection must be guaranteed.
Connecting to the mains
The terminal block and connection diagrams
can be found on the rear side of the oven.
1. Before accessing the terminals, switch off
all supply circuits and secure them against
being switched on again.
2. Make sure that all poles of the connection
cables are disconnected and that effec-
tive earthing is possible.
3. Connect the leads and, if necessary,
the enclosed brass bridges to the corre-
sponding contact terminals of the oven
power connection in accordance with the
circuit diagrams shown here.
4. Lay the connection cable behind the oven
so that it does not touch the rear wall of
the oven. The rear oven wall becomes hot
while it is in use.
