2) Initialization and grid check
Initialization in progress: input power is sufficient to feed the
inverter; AURORA is verifying start-up conditions (for instance:
input voltage value, insulation resistance value, etc.) and grid
monitoring routine has been launched.

3) AURORA is feeding the grid
After completing a set of electronics and safety auto-test routines,
the inverter starts the grid connection process.
During this stage AURORA automatically tracks and analyzes the
maximum power point (MPPT) of the wind generator.

4) Ground insulation fault
AURORA indicates that insulation resistance was found to be too
low.
This may be due to an insulation fault in the connection between
the wind generator inputs and the ground.
WARNING
: Shock hazard! Do not attempt to correct this fault
yourself. The instructions below have to be followed very
carefully. Unless you are qualified to work on the equipment,
contact a service professional.
What to do after an insulation fault has been found
When the red LED turns on, try to reset the fault indication by
pressing the multi-function ESC button at the right side of the
display. If the inverter reconnects to the grid, the fault was due
to a one-time event. If this fault occurs frequently, have the
system inspected by a service professional.
If the inverter does not reconnect to the grid, open both
disconnect switches to place AURORA into a safe condition and
contact an authorized service center to have the system repaired.
