Voltage Selector Switch- 3 Phase 480/277V Position
The following are additional voltages available when the volt-
age selector switch is in the ‘3 phase 480/277V’ position.
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 22, 480 volts can be obtained with 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 the lowest setting.
Single Phase: 480V, 440V, or 416 Volt
This setting can provide single phase power at 480, 440, or
416 volts. After hooking up the hard wires to the lugs as
shown in Figure 23, 480 volts can be obtained with the volt-
age 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 the lowest setting.
Single Phase: 277V, 254V, or 240V
This setting can provide single phase power at 277, 254, or
240 volts. After hooking up the hard wires to the lugs as
shown in Figure 24, 277 volts can be obtained with the volt-
age regulator knob turned toward maximum; 254 volts can
be obtained with the voltage regulator knob is turned down;
and 240 volts can be obtained with the voltage regulator
knob is at the lowest setting.
