* According to product standard IEC 62109, the ground conductor must
correspond to the phase cross-section for phase cross-sections ≤16 mm²,
while for phase cross-sections >16 mm², it must be at least 16 mm².
For a conductor cross-section of 1.5 mm
2
, the maximum permissible
cable length is 100 m.
** The cable cross-section must be dimensioned in accordance with the in-
stallation situation and the specifications of the battery manufacturer.
