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
IMPORTANT!
Repeat the procedure if the cable has been disconnected and is to be re-
connected.
AC terminals
Fronius Symo
Fronius Eco
PE
Ground conductor / earthing
L1-L3 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 fer-
rules 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-sec-
tion 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 fitted.
Cross-section of
the AC cable
When using an M32 metric screw joint (reducer removed):
cable diameter 11 - 21 mm
