According to product standard IEC 62109, the ground conductor must
correspond to the phase cross-section for phase cross-sections ≤16 mm²;
for phase cross-sections >16 mm², it must correspond to at least 16 mm².
The cable cross section must be dimensioned in accordance with the in-
stallation situation and the specifications of the battery manufacturer.
