Voltage Selector Switch
Voltages are selected using the Voltage Selector switch
(Figure 12) which is located above the output terminal
panel's hard wire hook-up panel. This switch has been
provided for ease of voltage selection.

CAUTION
NEVER change the position of the voltage selector
switch while the engine is running. ALWAYS place
the circuit breaker in the OFF position before selecting
voltage.
Voltage Regulator
To obtain some of the voltages listed in Table 7 will require
a fine voltage adjustment using the Voltage Regulator
control knob (Figure 13) located on the control panel.

GFCI Receptacle Load Capacity
The load capacity of the GFCI receptacles is directly related
to the voltage being supplied at either the output terminals
or the three twist-lock auxiliary receptacles.
Table 9 and Table 10 show what amount of power (kW) and
current (A) is available at the GFCI receptacles when the
output terminals and twist-lock receptacles are in use. Be
careful that your load does not exceed the available current
capacity at the receptacles.
