If you have installed the option L45-O6 (star to delta conversion) you get the following
additional wirings. The values in the column ‘Measuring channel numbers’ define the internal
calculation of the DSPs (the numbers are the numbers of the measuring channels!!). The
column ‘Circuit number’ defines the physical values of your circuit. This relations are correct,
