POSITIONING OF HOB The following operation requires building and/or carpentry work so must be carried out by a competent tradesman. Installation can be carried out on various materials such as masonry, metal, solid wood or plastic laminated wood as long as they are heat resistant (T 90°C). [. . . ] Carefully trim any excess from border C of the gasket. The distances in the following drawing refer to the hole on the inner side of the gasket. 21 Instructions for the installer 3. ELECTRICAL CONNECTION Make sure that the voltage and capacity of the power line conform to the data shown on the plate located under the casing. Do not remove this plate for any reason. The plug on the end of the supply cable and the wall socket must be the same type and conform to the current electrical system regulations. Check that the power line is adequately grounded. On the power line, install an omnipolar cut-off device with contact cut-off distance greater than or equal to 3 mm, located in an easily accessible position near the unit. Do not use reducers, adapters or shunts. If the power cable is replaced, the wire section on the new cable must 2 not be less than 0. 75 mm (3 x 0. 75 cable), keeping in mind that the end to be connected to the hob must have the ground wire (yellow-green) longer by at least 20 mm. Use only H05V2V2-F cable or similar which has a maximum temperature of 90°C. Any replacement needed should be carried out by a specialised technician who should make the mains connections according to the following diagram.
