NOTE: Only for “PG” and “SG” options: the current measuring inputs are galvanically insulated and therefore they can be connected to ground singly.

NOTE: For all models except for “PG” or “SG” the current inputs can be connected to the lines ONLY by means of current transformers. The direct connection is not allowed.
