It is necessary to ensure that potential difference between generator current COM terminal and
battery “-” terminal is maximally ± 2V. Therefore is strongly recommended to interconnect
these two terminals together.
Single phase application:
Connect CT according to following drawings. Terminals L2l and L3l are opened.
CT location
