2) AURORA initialization and grid check
Initialization in progress: input power sufficient to feed the
inverter; AURORA is verifying start-up conditions (for instance:
input voltage value, insulation resistance value, etc.) and grid
check routine is 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.
As mentioned above, during this stage AURORA automatically
tracks and analyzes the maximum power point (MPPT) of the
photovoltaic field.

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 photovoltaic field inputs and the ground.
WARNING : Shock hazard! Do not attempt to correct this fault
yourself. The instructions below have to be followed very
carefully. In case you are not experienced or skilled enough to
work safely on the machine, contact a specialized technician.
What to do after an insulation defect has been found
When the red LED turns on, try to reset the fault indication by
pressing the multi-function ESC key at the side of the display. If
AURORA reconnects to the grid, the fault was due to a transient
event (such as condensation and moisture getting into the
panels). If this trouble occurs frequently, have the system
inspected by a specialized technician.
If AURORA does not reconnect to the grid, open both the DC
and AC disconnect switches to place AURORA into a safe
condition and contact an authorized service center to have the
system repaired.
