Voltage Selector Switch- 3 Phase 240/139V Position
The following are additional voltages available when the volt-
age 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 26, 240 volts can be obtained with 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 the 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 27, 240 volts can be obtained with the volt-
age 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 the 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 28, 139 volts can be obtained with the volt-
age 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 the lowest setting.
