6.2.2 Connecting the AC Cable to the Sunny Central 350
The AC grid connection points are at the top of the AC cabinet.
The following illustration shows the connection points for the AC grid in the Sunny Central 350 as an
example.
Observe the field of rotation.
The field of rotation at the grid connection points must be right. If the field of rotation is not
right, the Sunny Central will output an error message.
Grid Structure
Sunny Centrals are configured for a TN-C grid connection. They can also be connected to
TN-S or TT grids. To do so, remove the jumper between N and PE on the grid connection.
An IT grid can be implemented specifically for each project. Contact the Sunny Central
Service Line.
Fuse Links
Fuse the grid connection cable at the nominal current indicated on the type plate. If the
specified nominal current differs from the nominal current of the fuse plug, use the fuse plug
with the next highest nominal current.
Position of the AC grid connection points
The exact position of the AC grid connection points differs depending on the model. The
exact position of the AC grid connection points can be determined with the help of the
equipment identifier and the circuit diagram enclosed.
