Max. cross-section of each conductor cab-
le:
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.
In the case of an AC cable with a cross-section of 16 mm², ferrules can either not be used
or only used to a limited extent depending on the type of ferrule and crimping.
Type of AC cable The following types of AC cable can be connected to the AC terminals of the inverter:
IMPORTANT! The resistance in the leads to the AC-side connection terminals must be as
low as possible for optimal functioning of grid monitoring.
min. 2,5 mm² - max. 16 mm²
