4 START-UP
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.
The start-up procedure is as follows:
1) Set the external DC disconnect, if present, (for the photovoltaic panels) to ON
2) Set the external AC disconnect (for the grid) to ON.
There is no specific order for closing the two disconnects.
WARNING
: This operation starts the connecting procedure for inverters. Do
not open the inverter or the switch box.
3) Once both disconnects are closed, the inverter starts the grid connection
sequence, unless the grid voltage and frequency parameters are found to be
outside the operating range as per the UL 1741 standard. The check routine is
indicated by the flashing green LED labelled POWER over the display.
The check routine may take from 30 seconds up to several minutes, depending on
grid condition. Three screens are shown on the display during the check routing:
•
“Measuring Riso…”, connection in progress with progress indication
(Riso = insulating resistance)
•
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; proper operation is indicated by a warning sound and the green LED
staying on steady. This means that sun radiation is sufficient to feed the grid.
5) If the grid check routine gives a negative result, the unit will repeat the
procedure until all grid voltage and frequency parameters and grid configuration
