GENERATOR OUTPUTS

GENERATOR OUTPUT VOLTAGES

A wide range of voltages are available to supply voltage for many different applications. Voltages are selected by applying jumpers (6) to the voltage change-over board (Figure 12). To obtain some of the voltages as listed in Table 7 (see below) will require a fi ne adjustment using the voltage regulator (VR) control knob located on the control panel.

Voltage Change-Over Board

The voltage change-over board (Figure 12) is located on the control box, behind the generator control panel. This board has been provided for ease of voltage selection.

Figure 12. Voltage Change-Over Board

CAUTION

NEVER attempt to place jumper plates on the voltage change-over board while the generator is in operation. There exist the possibility of electrocution, electrical shock or burn, which can cause severe bodily harm or even death!

These calculations refl ect the maximum amount of current the generator can provide at each output terminal pair. To obtain the total generator amperage, multiply by 3.

Example 1: 488.6 amps @ 120V per output terminal pair X 3 = 1,486 amps

Example 2: 244.3 amps @ 240V per out put terminal pair X 3 = 733 amps
