21Electric connectionThe mains connection must be carried out by an expertelectrician. The VDE-regulations and the valid pre-scriptions by the local power suppy boards have to becompiled with.Prior to connection it should be checked whether thevoltage stated on the type plate -- i.e. the nominal vol-tage of the appliance and of the oven/control box -- isidentical with the prevailing mains voltage. The typeplate ist located on the hobs bottom.The heating element voltage amounts to 230 V . Theappliance will also perfectly perform with the formermains voltage of 220 V .The mains connection must be carried out in a way thatan all--pole insulating device is existing with a contactopening of at least 3 mm, e.g. LS--automatism, earth--leakage circuit--breaker or fuse.A wire of type H05VV-F or of higher rating is to be usedas supply cable.The mains terminal is located in the bottom of theappliance behind a covering slide.According to existing mains voltage the appliance hasto be connected in correspondence with the diagramsof connecting possibilities. The bridges of the terminalboard are to be changed accordingly, if need be.The protective conductor is to be connected to terminal. The protective conductor must be longer than liveleads.The cable connections have to be established asprescribed and the terminal screws be firmly tigh-tened.Afterwards the supply cable has to be secured by strainrelief device and the covering slide must be closed.Prior to first use remove any possibly existing labelsand protective foils from the ceramic glass plate or theframe of the hob.After connection to the power supply all hea-ting elements are to be switched on shortly atmaximum setting one after another, in order tocheck the operability.Electrical connection 230 V ~strain relief deviceOpen the connection ter-minal with a screw driverChangeingconnectionbridgesL1 N51 2 3 4L1 L2 N51 2 3 4L1 L2 L3 N51 2 3 4L1 L251 2 3 4L1 L2 L351 2 3 4(L3)1 L + N2 L + N3 L + N2 L3 L230 V ~400 V 2 N ~400 V 3 N ~230 V 2 ~230 V 3 ~
