NOTES: -- For lines at 210 VAC or below an auxiliary boost transform er is required to adequate the line voltage to the Generator input.
-- For 80 kW Generators operating with lines at 400 / 415 / 440 VAC an auxiliary boost transformer is required to adequate
the line voltage to 480 VAC (or 530 VAC).
