Note 1:  See power output chart

Note 2:  Warning: Do not exceed 10 KW  (45 FLA @ 220 V)

Note 3:  Generator power is routed through a transfer switch that arbitrates whether utility power or wind generated power is connected to the load based on wind speed.  The transfer switch disconnects utility power in a break before make configuration and connects 60 Hertz synchronized wind generator power to the load.

Note 4:  30 feet of clear vertical height relative to surrounding structures must be attained to reach rated power output.
