This section of the menu is available only for the Italian country standard.
The autotest according to the grid standard CEI-021 can be launched via
the menu on the display.
The conditions required to perform an Autotest are:

• You must not intervene in any way while the test is underway
• You must check that the equipment has a stable grid connection.
In the Autotest section of the SETTINGS menu, select the type of test the
equipment is to run from the following:
OV Test – parameters:
U>>; U>; U> (10Min)
Disconnection from the distribution grid due to "Over-voltage"
UV Test – parameters:
U<<; U<
Disconnection from the distribution grid due to "Under-voltage"
OF Test – parameters:

If one of the protections is disabled (from the Service menu), N/A (not
applicable) will appear next to the name of the test.
While one of the tests is being performed, the set limits will be gradually
increased/reduced (depending on the type of test) until the threshold at
which the inverter is disconnected from the grid is reached. The procedu-
res for running the Autotest comply with the legislation in force.
The display shows the message "Performing Test" when the test has
started.
