2.6 AC Grid Connection

These instructions for AC grid connection are for qualified
personnel only. To reduce the risk of electric shock, do not
perform any maintenance work other than that specified
in the manual unless you are qualified to do so.
For fuse and RCD information, refer to Section
5, page 41. AC fuse rating must not exceed the ampacity
of the conductors used.
IMI Detection
The inverter has a built-in IMI/RCMU (Insulation Monitoring
Interrupter / Residual Current Monitoring Unit). The inverter
acts on residual DC current and a sudden change in the
ground fault current. This functionality is activated during
normal operation.
Insulation Resistance Detection
The inverter has a built-in insulation resistance detection. The
insulation resistance detector performs a measurement of
the connected PV system resistance to ground before the
inverter connects to the grid. If the resistance is below the
grid code set value, the inverter will wait and re-measure the
resistance after a short while. When the resistance is above
the grid code set value, the inverter performs a self-test and
connects to the grid.

INFORMATION
Cables with multi-strand, fine-strand or extra
fine-strand conductors can be used for AC
connection (see figure 2.15 and 2.16). The cables
must be suitable for a temperature of at least 75°C.
When using fine-strand or extra fine-strand
conductors, bootlace ferrules must be used for the
connection.
