21Electrical connectionPrior to making the electric al connection, make surethat:- The protection fuse and the domestic wire systemare suitable to carry the total electric load of the oven(see rating plate).- Your domestic wiring system has an efficient earthconnection in compliance with the rules and laws inforce.- The wall socket or the omnipole switch used for theelectrical connection can easily be reached after theoven is built in.The appliance is delivered without an electric supply cable,therefore, you will have to fit to it a supply cable withstandard plug, suitable for the total electric load shownon the rating plate.The plug is to be inserted into a suitable wall socket.If you require a direct connection to the electric network(mains), it will be necessary to fit between the applianceand the mains an omnipole switch, aith a minimum gapbetween contacts of 3 mm. suitable for the required loadand in compliance with rules in force. The green 1 yellowground wire must not be interrupted by the switch.The supply cable must in all cases be laid out in such away as to ensure that it does not reach at any givenpoint a temperature 50∞C higher than the ambient tem-perature.The manufacturer disclaims any liability in case theseaccident-preventing rules are not observed.Suitable power supply cables are the following types,considering the respective necessary section of cable.ï H07 RN-Fï H05 RN-Fï H05 RR-Fï H05 VV-Fï H05 V2V2-F (T90)Connecting the terminal boardThe appliance incorporates an easily accessible 6-poleterminal board whose jumpers (bridges) are already pre-set for operation on 400 V three-phase with neutral wire.In case where different mains voltage is present, thejumpers on the terminal board must be arranged as shownin the diagram.The ground cable must be connected to terminal .After connecting the supply cable to the terminal board,secure it with a junction clamp.230V 3~ 1 2 3 4 5L1 L2 L3 PE230V 1~ 1 2 3 4 5L1 N PE400V 2N~ 1 2 3 4 5L1 L2 N PE400V 3N~ 1 2 3 4 5L1 L2 L3 N PESectionof cable(min.)4 x 1.5 mm2Sectionof cable(min.)3 x 2.5 mm2Sectionof cable(min.)4 x 2.5 mm2Sectionof cable(min.)5 x 1.5 mm2
