Fronius Symo 15.0-3-M Installation Instructions

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
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 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-
