Figure 19. Voltage Regulator Knob
3 Phase, 480V, 440V, or 416 Volt
This setting can provide 3-phase power at 480, 440, or
416 volts. After hooking up the hard wires to the lugs as
shown in Figure 20, 480 volts can be obtained the
voltage regulator knob turned toward maximum; 440 volts
can be obtained with the voltage regulator knob is turned
down; and 416 volts can be obtained with the voltage
regulator knob is at lowest setting.
