Fronius Symo 15.0-3 208 - Permitted AC 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 net-
works (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
