Important! Grounding of the cable shield must be effected at the cable side
For busbar-side grounding of the current transformers, the current polarity of the device is changed via
address 0201. This also reverses the polarity of the current input IN/INs. When using a cable-type current
transformer, the connection of k and I at F8 and F7 must be exchanged.

Current transformer connections to two phase currents and two ground currents; IN/INs –
ground current of the line, IN2 – ground current of the transformer starpoint
