4 STARTING UP AND SWITCHING THE INVERTER OFF
WARNING: Do not place any items on the AURORA inverter during
operation.
WARNING: Do not touch the heat sink when the inverter is operating, as
some parts may be hot and cause burns.
4.1 Start-Up Procedure
WARNING: To start the inverter a DC voltage of at least 130V can be
supplied or, with no DC present but with grid voltage present, press on the
side key indicated as STBY SUPPLY for at least 2 seconds. The position of
the key is shown in Fig. 21. For further information on the use of the start-up key,
please refer to 4.2.
Depending on the DC input voltage present, the inverter behaves as follows:
a) When the inverter is switched off, it will start as soon as the input voltage
value of 130 Vdc is reached.
b) The inverter will display the message 'Waiting Sun' until the input voltage
exceeds the set Vin start value (see paragraph 5.5.6.8).
c) When the Vin start value is exceeded, the inverter will display the message
Vac absent if the grid is not connected or it will connect to the grid if it is
there.
d) The inverter will remain connected to the grid if the input voltage is between
70% of the Vin start set and 520 Vdc. If the input voltage value is outside this
range, the inverter disconnects itself from the grid.
The procedure for commissioning AURORA is the following:
1) Set the inverter's integrated DC disconnect switch (for the photovoltaic panels)
to ON
2) Set the AC disconnect switch (for the grid) external to the inverter to ON.
There is no specific order for closing the two switches.
