**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. 

**ATTENTION:** only one ammeter input can be connected to earth, as shown in the electrical diagrams.
