Permitted cables
for the data com-
munication area
Cables with the following design can be connected to the terminals of the inverter:
- Copper: round, solid
- Copper: round, fine-stranded
IMPORTANT!
Connect the individual conductors to an appropriate ferrule if several individual conduct-
ors are connected to one input of the push-in terminals.

Fronius recommends using at least CAT 5 STP (shielded twisted pair) cables and a maximum distance of
100 m (109 yd).
Cross section of
the AC cable
For a standard M32 metric screw joint with a reducer:
Cable diameter from 7-15 mm
When using an M32 metric screw joint (reducer removed):
cable diameter from 11-21 mm
(with a cable diameter of less than 11 mm, the strain-relief force is reduced from 100 N to
a maximum of 80 N)
