167Contrary to the Regulations for House Installations ofthe SEV, par. 47330.1, the built--in appliance may beinstalled in flammable material. Parts, side panels,reinforcement rails etc., which protrude into the spacebelow the cooking zones must be made of inflammablematerials.Limitation of this space: width 550 mm, height 20 mmfrom the underside of the hob, depth 60 mm from be-hind for a worktop depth of 600 mm. Inflammable wallsand ceilings must be fitted with fire--resistant coatingsabove the cooking surface, in accordance with the firebrigade regulations for the respective area.Electrical connectionsBefore connecting the appliance, check that the vol-tage quoted on the rating plate -- that is, the nominalvoltage of the appliance -- corresponds to the availablemains voltage. The rating plate can be found on the lo-wer housing of the glass--ceramic hob.The mains connection of the ceramic hob must takeplace using the provided connection cable in accor-dance with the connection diagram (Fig. 3), and mustbe carried out so that it is possible to disconnect all po-les with a contact opening of at least 3 mm, e.g., usingan LS circuit breaker, earth--leakage circuit breaker, orfuse.If the mains connection cable has to be replaced,a cable with Spare Parts No. 374 3700 00/1 must beused.Remove any protective films from the cooking surface.After connecting the electrical supply, all coo-king zones should be briefly switched on oneafter the other at their maximum power, in or-der to test whether they are operational.braun = brownschwarz = blackblau = bluegrün/gelb = green/yellowbrun = brownnoir = blackbleu = bluevert/jaune = green/yellowmarón = brownnegro = blackazul = blueverde/amarillo = green/yellowFig.3Ågrün--gelb / verde--amarillovert--jauneblau / azul / bleuElektrischer Anschlussconexión elèctricaconnexion électriqueAnschlussleitung Muldeconexiòn artesacâble de raccordementPENL2L1ÖÑÉÇschwarz / negro / noirbraun / marrón / brun230V~ÅPENL1ÖÑÉÇ230V~grün--gelb / verde--amarillovert--jauneblau / azul / bleuschwarz / negro / noirbraun / marrón / brunElektrischer Anschlussconexión elèctricaconnexion électriqueAnschlussleitung Muldeconexiòn artesacâble de raccordementElektrischer Anschlussconexión elèctricaconnexion électriqueAnschlussleitung Muldeconexiòn artesacâble de raccordement
