Current transformer connections to two phase currents and two ground currents;
I
N/INs – ground current of the line,
I
G2 – ground current of the transformer starpoint
Important!
Grounding of the cable shield must be effected at the cable's side
For busbar-side grounding of the current transformer, the current polarity of the device is changed via address
0201. This also reverses the polarity of current input IN/INs. When using a cable-type current transformer, the
connection of k and l at Q8 and Q7 must be changed.
