•
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
damage 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
supply 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
following 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.
