AURORA is in the disconnection phase; this happens whenever
the input power is too low to export power to the feed grid and
power the inverter control system as well.

2) AURORA Initialization and Grid Check
The unit is in the initialization phase: energy supply for the
inverter control system is high enough. AURORA is also
checking that starting conditions – such as input voltage, starting
time, etc. - necessary for the initialization process, are satisfied.
Grid check is then started.

3) AURORA Under Production
Once all electronic and safety self-tests are over, the unit starts the
exporting process.
As stated above, during this phase AURORA carries out an
automatic search and analysis of the wind turbine power curve
max power point tracking (MPPT).

4) Ground Insulation
The inverter signals a ground fault.
This can be due to an insulation defect in the wind input
connection.
Insulation Defect
An insulation fault condition has been detected in the input
wiring from the Wind Interface box or a corresponding
connection is conductive with the grounded potential.
WARNING: Trying to remove the fault by yourself is
extremely dangerous. The instructions below have to be
followed very carefully. In case you are not experienced or
skilled enough to work safely on the unit, contact a specialized
technician.
What to do after an insulation defect has been found
Whenever the red LED comes on, press the special multifunction
push-button next to the LCD side to reset it. If this fault can be
reset, the AURORA will continue working. If the fault cannot be
