At the end of the first starting of the inverter, the wiring box must be configured using the
dedicated Aurora Manager software. The software and relevant manual for carrying out this
configuration are contained in the CD supplied with the inverter.
• At this point the b17 icon will flash, this indicates the start-up of the DC-
DC circuit (booster) part. This icon will remain permanently switched on
when the DC-DC will be operating at steady state (the flashing of the icon
usually lasts a few seconds).
Immediately after this, the b18 icon, which indicates the AC-DC circuit
(inverter) part, will also behave normally.
• Immediately after this the grid connection will start. During this phase
the icons will be displayed in sequence on the b21 board until the con-
nection of the inverter. After the inverter is connected, the icons on the
whole line b21 will come on steady.
If the inverter disconnects from the grid, the icons of the left side (cable
and plug) of the line b21 will stay on.
• Once the connection sequence has been completed, the inverter starts
to operate and indicates its correct operation by making a sound and by
the green LED coming on steady on the LED panel
is sufficient solar radiation to feed power into the grid.

• If the checking of the grid does not give a positive result, the unit will
repeat the procedure until all the parameters that allow connection to
the grid (grid voltage and frequency, insulation resistance) are within the
range. During this procedure, the green LED flashes.
