Fixing

The appliance must be installed on a perfectly level supporting surface.

Any deformities caused by improper fixing could affect the features and operation of the hob.

The thickness of the supporting surface should be taken into account when choosing the length of the screws for the fixing hooks:

•30 mm thick: 17.5 mm screws

•40 mm thick: 7.5 mm screws

Fix the hob as follows:

1.Use short flat-bottomed screws to fix the 4 alignment springs in the holes provided at the central point of each side of the hob.

2.Place the hob in the cavity, make sure it is in a central position and push down on the whole perimeter until the hob is stuck to the supporting surface.

3.For hobs with raised sides: After inserting the hob into its cavity, insert the 4 fixing hooks (each has its own pin) into the lower edges of the hob, using the long pointed screws to fix them in place, until the glass is stuck to the supporting surface.

!The screws for the alignment springs must remain accessible.

!In order to adhere to safety standards, the appliance must not come into contact with electrical parts once it has been installed.

!All parts which ensure the safe operation of the appliance must not be removable without the aid of a tool.

Electrical connection

!The electrical connection for the hob and for any built-in oven must be carried out separately, both for safety purposes and to make extracting the oven easier.

Single-phase connection

GB

The hob is equipped with a pre-connected electricity supply cable, which is designed for single-phase connection. Connect the wires in accordance with the instructions given in the following table and diagrams:

Voltage and	Electrical cable	Wire connection
mains frequency
230-240V 1+N ~		: yellow/green
		N: the two blue wires together
220-240V 1+N ~
		L: brown and black together
50/60 Hz

Other types of connection

If the mains supply corresponds with one of the following:

Voltage and mains frequency

•400V - 2+N ~ 50/60 Hz

•220-240V 3 ~ 50/60 Hz

•230-240V 3 ~ 50/60 Hz

•400V - 2+2N ~ 50/60 Hz

Separate the wires and connect them in accordance with the instructions given in the following table and diagrams:

Voltage and	Electrical cable	Wire connection
mains frequency
400V - 2+N ~		: yellow/green;
50/60 Hz		N: the two blue wires
230-240V 3 ~		together
220-240V 3 ~		L1: black
50/60 Hz		L2: brown
		: yellow/green;
400V - 2+2N ~		N1: blue
50/60 Hz		N2: blue
		L1: black
		L2: brown

If the mains supply corresponds with one of the following:

Voltage and mains frequency

•400V 3 - N ~ 50/60 Hz proceed as follows:

Terminal board

UNDERSIDE OF HOB

On the lower part of the appliance there is a connection box for the different types of electricity supply (the picture is only an indication and is not an exact representation of the purchased model).

!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 cross section: 25 mm).

2.To open the terminal board, use a screwdriver as a lever under the side tabs of the cover (see Terminal board picture).

3.Loosen the cable clamp screw and the terminal board screws in accordance with the type of
