Voltage Selector Switch- 3 Phase 480/277V Position
The following are additional voltages available when the
voltage selector switch is in the 3 phase 480/277V
position. (See figure 25 below.)
3 Phase, 480V, 440V, or 416 Volt
The following connection, with the voltage selector switch
locked into the 3 phase 480/277V position (See Figure 26),
can offer THREE PHASE power at 480V, 440V, or 416V.
After hooking up the hard wires to the lugs as shown in
figure 28 below, 480V will be the voltage with the Voltage
Regulator Knob turned toward maximum. 440 volt will be
reached when the Voltage Regulator Knob is turned down,
and 416 volt when the Voltage Regulator Knob is toward
the lowest setting (See Figure 26).
Single Phase: 480V, 440V, or 416 Volt
The following connection, with the voltage selector switch
locked into the 3 phase 480/277V position (See Figure 25),
can offer SINGLE PHASE power at 480V, 440V, or 416V.
After hooking up the hard wires to the lugs as shown in
Figure 28 below, 480V will be the voltage with the Voltage
Regulator Knob turned toward maximum. 440 volt will be
reached when the Voltage Regulator Knob is turned down,
and 416 volt when the Voltage Regulator Knob is toward
the lowest setting (See Figure 26).
Single Phase: 277V, 254V, or 240V
The following connection, with the voltage selector switch
locked into the 3 phase 480/277V position (See Figure 26),
can offer SINGLE PHASE power at 277V, 254V, or 240V.
After hooking up the hard wires to the lugs as shown in
Figure 29 below, 277V will be the voltage with the Voltage
Regulator Knob turned toward maximum. 254 volt will be
reached when the Voltage Regulator Knob is turned down,
and 240 volt when the Voltage Regulator Knob is toward
the lowest setting (See Figure 26).
