The twoinductors can be seen in the photograph.The inductor contains an NTC sensor that measures the temperatureof the inductor and protects it against excessive temperatures.Moreover, it serves to measure the temperature at which the residualheat indicators turn on.The mica sheet serves as electrical insulation between the inductorand the glass. This sheet is installed without glue, wherefore it can bereplaced in the event that it is damaged.The inductor unit must be connected according to the schematic thatis shown in the following images.Caution!It is vitally important that all connections be made with the correctpolarity in order to ensure the operation of the dual, 280-mm zone.The cable with the red mark has been replaced by a blue cable.In other words, the two blue cables must both be positioned in theinterior or they must both be positioned in the exterior, symmetrically.
