The winding of the 1FE218x for the connection of the free cable ends of the same phases is
a parallel circuit from two partial windings.
This produces the following conversion:

The indexes refer to the winding halves 1 or 2. The value without index designates the value for the
complete motor.
The connection cables and the water quantity are halved on the hardware.
