Ground-Current Acquisition
(Address 50) This register defines the ground-current sensor which is either used or not used in the isolated/
resonant-ground connection. If the ground-current sensor is used for isolated/resonant-ground connection,
the ground current is measured. If the ground-current sensor is not used for isolated/resonant-ground connec-
tion, the ground current is calculated.
