Any failure of the inverter when it is not connected to earth through the appropriate terminal is not
covered by the warranty.

The values are calculated in nominal power conditions, considering:
- loss of power along the line no greater than 1%.
- use of copper cable, with HEPR rubber insulation and positioned in open air.
For the connection to the inverter grid you need 3 connections: ground,
neutral and phase. The ground connection to the inverter is obliga-
tory.
Plug the grid cable into the inverter using the specific AC cable gland
and connect the AC output screw terminal block
Use a properly sized tripolar cable and check the tightness of the AC
cable gland

The cross-section of the AC line conductor must be sized in order to
prevent unwanted disconnections of the inverter from the grid due to
high impedance of the line that connects the inverter to the power supply
point; In fact, if the impedance is too high, it causes an increase in the
AC voltage that, on reaching the limit set by the country of installation,
causes the inverter to switch off.
The table shows the maximum length of the line conductor based on the
cross-section of this conductor:
