Fronius 10.0-3 208-240 - Permitted Cables

NOTE!
When connecting aluminum cables:
▶
Follow all national and international guidelines regarding the connection of aluminum
cables.
▶
Follow the instructions of the cable manufacturer, especially the note about whether
an annual check to ensure that the cables are firmly attached should be performed.
NOTE!
Form a min. 4 in. (100 mm) cable loop with all cables.
NOTE!
To ensure that the inverter operates without any problems:
▶
Make sure that the grid's neutral conductor is grounded. For insulated networks
(without grounding), this is not the case, and operation of the inverter is not possible.
▶
A neutral conductor is required for measurement purposes when operating the
inverter. The neutral conductor must have a current carrying capacity of at least 1 A.
Permitted cables AC cables with the following design can be connected to the AC terminals of the inverter:
Cu / Al Cu
- Copper (Cu) or aluminum (Al): round, solid
- Copper: round, stranded, up to conductor class 4
AC & DC = copper cables (Cu)
The following wire combinations can be used for wiring.
Select a sufficiently large cable cross-section based on the actual device output!
