AC terminals
PE Ground conductor / earthing
L1 Phase conductor
N Neutral conductor
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.
Type of AC cable The following types of AC cable can be connected to the AC terminals of the in-
verter:
-
Copper or aluminium: solid round conductor
-
Copper: fine-stranded round conductor, up to conductor
class 4
Preparing the
aluminium
cables for con-
nection
The AC-side terminals are suitable for connecting single-wire, round aluminium
cables. Because of the formation of a non-conductive oxide layer due to the re-
action of aluminium with air, the following points must be considered when con-
necting aluminium cables:
-
the reduced rated currents for aluminium cables
-
the connection conditions listed below
Always follow the cable manufacturer instructions when using aluminium cables.
When designing cable cross-sections, take local regulations into account.
Connection conditions:
1
Carefully clean the oxide layer from the bare end of the cable by scraping it,
e.g. with a knife
IMPORTANT! Do not use brushes, files or emery paper, as the aluminium
particles get trapped and can be transferred to other conductors.
2
Once the oxide layer is removed, rub the end of the cable with a neutral
grease, such as non-acidic and non-alkaline Vaseline
3
Immediately connect the cable end to the terminal
