DCA-25SSI — OUTPUT VOLTAGE SETUP

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.

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 21, 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.

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.
