Max. cross-section of each conductor cable:
16 mm²
Min. cross-section of each conductor cable:
in accordance with the fuse rating on the AC side, but at least 2.5 mm²
The AC cables can be connected to the AC terminals without ferrules.
IMPORTANT! When using ferrules for AC cables with a cross-section of 16 mm²,
the ferrules must be crimped with a right-angled cross-section.
The use of ferrules with insulating collars is only permitted up to a max. cable
cross-section of 10 mm².
For a power category of 10-12 kW, an M32 PG gland (ø 7-15 mm) is fitted.
For a power category of 15-17.5 kW, an M32 PG gland is fitted (ø 18-25 mm) and
an M32 PG gland (ø 7-15 mm) supplied.
From a power category of 20 kW upwards, an M32 PG gland (ø 18-25 mm) is fit-
