Figure C-5 Current transformer connections to two phase-current transformers and a ground-current
transformer; the ground current is taken via the highly sensitive and sensitive ground input.
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 trans-
former, the connection of k and l at Q8 and Q7 must be changed.
