4 START-UP
NOTE: do not lay any object on AURORA during operation.
WARNING: do not touch the heat sink during operation, some parts could be very hot and cause serious burns.
To turn on AURORA by turning ON the AC disconnecting means after allowing the wind turbine to turn.
1)To turn on the AURORA WIND Inverter the Wind Turbine via the Wind Interface Box must supply at least 50 VDC at the AURORA WIND Inverter Input Terminals.
2)When the control power threshold voltage is met the green power LED on the inverter will start to blink.
3)Switch the Ac disconnect to the ON position.
4)AURORA will start operating and the green LED labeled Power on the front panels will start blinking while the grid is checked to make sure that voltage, impedance and frequency parameters are within operating range requirements. The check can last several minutes depending on the conditions of the grid. During the check the LCD display will show a sequence of three screens, indicating:
•Remaining time for next connection.
•Grid voltage value and status (in or out of range)
•Grid frequency value and status (in or out of range)
5)If the grid check is successfully and the input power has remained above the 50 V control power threshold the inverter will connect to the grid.
6)Then the AURORA will export to the grid and the green Power LED will be continuously lit (provided there is enough wind input power to feed power to the grid).
7)If the grid check is not successful the unit repeats the check over and over again until acceptable grid parameters are found. During this procedure the green power LED keeps blinking. Measure the grid voltage and frequency and then verify the grid configuration of the unit.
