DCA-25USI — GAUGE READING/TERMINAL PANEL CONNECTIONS

Voltage Selector Switch

The voltage selector switch (Figure 15) is located above the output terminal panel’s Hard Wire Hook-up Panel. It has been provided for ease of voltage selection.

Figure 15. Voltage Selector Switch

Voltage Selector Switch Locking Button

The voltage selector switch has a locking button to protect the generator and load from being switched while the engine is running. To lock the voltage selector switch, press and hold the red button located at the bottom of the switch.

CAUTION - CHANGINGVOLTAGES

NEVER change the position of the voltage selector switch while the engine is running. ALWAYS place circuit breaker in the open position before selecting voltage.

Generator OutputVoltages

A wide range of voltages are available to supply voltage for many different applications. Voltages are selected by using the voltage selector switch (Figure 15). To obtain some of the voltages as listed in Table 7 (see below) will require a fine adjustment using the voltage regulator (VR) control knob located on the control panel.

Table 7. Voltages Available

Three Phase	208V	220V	240V	416V	440V	480V
(Switchable)
Single Phase	120V	127V	139V	240V	254V	277V
(Switchable)

Maximum Amps

Table 8 shows the maximum amps the generator can pro- vide. DO NOT exceed the maximum amps as listed.

GFCI Receptacle Load Capability

The load capability of the GFCI receptacles is directly re- lated to the voltage being supplied at either the output termi- nals or the 2 twist lock auxiliary receptacles.

Tables 9 and 10 show what amount of current is available at the GFCI receptacles when the output terminals and twist lock receptacles are in use. Be careful that your load does not to exceed the available current capability at the recep- tacles.
