4 START UP
WARNING: Do not place any items on AURORA during operation.
WARNING: Do not touch the heat sink when the inverter is operating, as
some parts may be hot and cause burns.
Start-up procedure:
1) Switch the AC breaker ON. If the speed of the turbine is high enough to
generate at least 50V DC on the rectifier output, the AURORA inverter will turn
on (the display lights on). Note that the inverter is powered directly from the wind
generator; therefore if the turbine is not rotating, the inverter will turn OFF.
2) Switch the Grid DC breaker ON.
3) Once both breakers are ON, the inverter starts the grid connection sequence.
The check routine may take from 30 seconds up to several minutes, depending on
grid condition. The routine is indicated by the flashing green LED marked
POWER.
Three screens are shown on the display during the check routine:
• Measuring isolation resistance: “Measuring Riso…” , connection in
progress with progress indication.
• Grid voltage value and status compared to specified values
(within/outside range).
• Grid frequency value and status compared to specified values
(within/outside range).
4) When the connection sequence is completed, the AURORA inverter starts
operating. Normal operation is indicated by a warning sound and the green LED
staying permanently ON. This means that wind energy is sufficient to export power
to the grid.
• If the check routine gave a negative result, the inverter will repeat the
procedure until all grid voltage and frequency parameters and grid
configuration are found to be in the specified range. During this process,
the green LED will keep flashing.
