Voltage Selector Switch- 3 Phase 240/139V Position
The following are additional voltages available when the
voltage selector switch is in the 3 phase 240/139V
position.
3 Phase, 240V, 220V, or 208 Volt
This setting can provide 3-phase power at 240, 220, or
208 volts. After hooking up the hard wires to the lugs as
shown in Figure 24, 240 volts can be obtained the
voltage regulator knob turned toward maximum; 220 volts
can be obtained with the voltage regulator knob is turned
down; and 208 volts can be obtained with the voltage
regulator knob is at lowest setting.
Single Phase: 240V, 220V, or 208 Volt
This setting can provide single phase power at 240, 220,
or 208 volts. After hooking up the hard wires to the lugs
as shown in Figure 25, 240 volts can be obtained the
voltage regulator knob turned toward maximum; 220 volts
can be obtained with the voltage regulator knob is turned
down; and 208 volts can be obtained with the voltage
regulator knob is at lowest setting.
Single Phase: 139V, 127V, or 120V
This setting can provide single phase power at 139, 127,
or 120 volts. After hooking up the hard wires to the lugs
as shown in Figure 26, 139 volts can be obtained the
voltage regulator knob turned toward maximum; 127 volts
can be obtained with the voltage regulator knob is turned
down; and 120 volts can be obtained with the voltage
regulator knob is at lowest setting.
