Routing of the AC cables inside the inverter must be carried out from the
right side of the inverter.
Depending of the version of the AC panel installed on the inverter it will
be necessary to route the AC output and ground cables into different
ways:
- Single-core configuration (default): 3xM40 cable glands
"R", "S", "T" phases and a M32 cable gland
In this configuration the AC output and ground cables must be inserted
into the proper cable glands, trying to follow a logical order based on the
position of the internal connections:
R = Phase R (indicated with a label near the AC connection busbar
S = Phase S (indicated with a label near the AC connection busbar
T = Phase T (indicated with a label near the AC connection busbar
The ground connection can be made using the Protective earth point (int.)
