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
be made only by an authorised elec-
trician
approved by the local energy
supply company, e.g. our Service de-
partment (see page EN-24). 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 oven is designed for the following al-
ternating voltages:
– 230 V 1N~ / 50 Hz, 40 A
– 400 V 2N~ / 50 Hz, 25 A
– 400 V 3N~ / 50 Hz, 16 A
– A separate power supply is required.
– The power cord used must comply with
the requirements of DIN EN 60335-1 (e.g.
H05RR-F model).
– Depending on the type of connection, the
conductor cross-section must be selected
and the contact bridges inserted or re-
moved (see following figures).
– 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 cooker
power connection in accordance with the
circuit diagrams shown here.
4. Lay the connection cable behind the
stove so that it does not touch the rear
wall of the cooker. The rear cooker wall
becomes hot while it is in use.
