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!
