Technical characteristics
Electrical connection
• The electrical safety of this appliance can only be
guaranteed if the latter is correctly and efficiently
earthed, in compliance with regulations on electrical
safety. Always ensure that this vital safety measure has
been taken. If you have any doubts, call in a qualified
technician to check the electrical system thoroughly.
•
The manufacturer denies all responsibility for dam-
age resulting from a system which has not been
earthed correctly.
• Before powering the appliance, check whether the
technical characteristics featured on the appliance data
plate correspond with those of the mains electrical
system.
• Check that the current load of the mains supply and
of the power sockets is suitable for the maximum power
of the appliance, indicated on the appliance data plate.
If in doubt, contact a qualified professional.
Disconnect the appliance from the electricity supply
before all operations.
Connect your hob to the electrical system by means of a
junction box: if the appliance is connected permanently
to the mains, an omnipolar circuit breaker, accessible if
necessary, with a minimum contact opening of 3 mm
should be installed.
Single-phase connection
The hob is equipped with a preconnected electricity sup-
ply cable, which is designed for single-phase connection.
Connect the wires according to the instructions given in
the following table and diagrams:

Other types of connection
If the mains supply corresponds with one of the following:
Voltage and mains frequency
• 400V - 2+N ~ 50 Hz
• 230V 3 ~ 50 Hz
• 400V - 2+2N ~ 50 Hz
Separate the wires and connect them according to the
instructions given in the following table and diagrams:

If the mains supply corresponds with one of the following:
Voltage and mains frequency
• 400V 3 - N ~ 50 Hz
proceed as follows:
! The cable provided is not suitable for the following types
of installation.
1. Use a suitable supply cable, H05RR-F or higher, with
the right dimensions (cable section: 2.5 mm).
2. To open the terminal board, insert a screwdriver into
the side tabs of the cover and open it (
see Terminal board
picture
).
3. Loosen the cable clamp screw and the terminal board
screws according to the type of connection required and
position the connection supports as shown in the follow-
ing table and diagrams.
4. Position the wires according to the following table and
diagrams and connect the appliance by tightening all the
screws for the springs as much as possible.

Warning: If the hob is fitted above a built-in oven, the hob
and the oven must be connected to the mains separately for
safety reasons and to simplify operations when it is necessary
to pull the oven out for some reason.
