Diversion Load Connection
The value of the Diversion Load resistor is determined by the wind system
manufacturer using wind generator characteristics.
•
Connect the Brake – terminal to the corresponding terminal properly sized
diversion load.
•
Connect the Brake + terminal to the corresponding terminal of the properly
sized diversion load.
•
Measure the resistance between the Brake – terminal and the Brake + terminal.
•
The resistance value should be equivalent to the diversion load resistance
value.
3.4
Bulk Output DC Connections
The Bulk Output DC connections provide the input to the Aurora Wind Inverter. The
polarity of these connections is critical for proper operation and to prevent damage to
the Aurora Wind Inverter.
•
Connect the Bulk Out + terminal to the IN+1 terminal in the Aurora wind
inverter
•
Connect the Bulk Out- terminal to the IN-1 terminal in the Aurora wind inverter
•
Verify that the polarity of the wiring is correct.
3.5
Wind Input Connections
The wind turbine needs to be safety brake to a zero energy state before terminating
the wind input wiring in the WBI. Verify that no voltage is present before terminating
the wiring.
•
Wind Input 1 connect a single wire (Phase A) to the terminal
•
Wind Input 2 connect a single wire (Phase B) to the terminal
•
Wind Input 3 connect a single wire (Phase C) to the terminal
3.6
Commissioning Sequence:
The commissioning of the wind energy system must be performed by trained and
qualified wind energy professional due to the potential hazards involved.
3.6.1 Wiring Verification
•
Verify Diversion Load connections (if installed).
•
Verify Wind turbine input connections.
•
Verify Aurora Wind Inverter is correctly and fully installed.
