* 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.
Permissible
cables for the
data communic-
ation connection
Cables with the following design can be connected to the terminals of the invert-
er:
-
Copper: round, solid
-
Copper: round, fine-stranded
IMPORTANT!
Connect the individual conductors to an appropriate ferrule if several individual
conductors are connected to one input of the push-in terminals.
