The selection of the rst current measurement channel's (IL1) polarity (direction).
The default setting is for the positive current to flow from connector 1 to connector
2, with the secondary currents' starpoint pointing towards the line.

The selection of the second current measurement channel's (IL2) polarity
(direction). The default setting is for the positive current to flow from connector 3 to
connector 4, with the secondary currents' starpoint pointing towards the line.
IL3
Polarity
0: -
1: Invert -
0: -
The selection of the third current measurement channel's (IL3) polarity (direction).
The default setting is for the positive current to flow from connector 5 to connector
6, with the secondary currents' starpoint pointing towards the line.
