280 + 180 left inductor unit

4.5.1
Overview
The 280/180 dual inductor is formed by two inductors: a 180-mm
internal inductor and a 280-mm diameter external inductor. The two
inductors can be seen in the photograph.
The inductor contains an NTC sensor that measures the temperature
of the inductor and protects it against excessive temperatures.
Moreover, it serves to measure the temperature at which the residual
heat indicators turn on.
The mica sheet serves as electrical insulation between the inductor
and the glass. This sheet is installed without glue, wherefore it can be
replaced in the event that it is damaged.
The inductor unit must be connected according to the schematic that
is shown in the following images.

Caution!
It is vitally important that all connections be made with the correct
polarity 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The cable with the red mark has been replaced by a blue cable.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 the
interior or they must both be positioned in the exterior, symmetrically.
