GENERATOR OUTPUTS
GENERATOR OUTPUT VOLTAGES
A wide range of voltages are available to supply voltage for
many different applications. Voltages are selected by using
the voltage selector switch (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 Selector Switch
The voltage selector switch (Figure 12) is located above
the output terminal panel’s Hard Wire Hook-up Panel. It
has been provided for ease of voltage selection.
Figure 12. Voltage Change-Over Board
Voltage Selector Switch Locking Button
To lock the voltage selector switch, press and hold the
red button located at the bottom of the switch. While
holding the red button down, insert a pad lock into the hole
next to the button to retain it in the inward locked position.
When the lock is removed, the red button is spring loaded
and will return to its normal outward unlocked position
switch.
CAUTION
NEVER change the position of the voltage selector
switch while the engine is running. ALWAYS place
circuit breaker in the OFF position before selecting
voltage.

Maximum Amps
Table 8 shows the maximum amps the generator can
provide. DO NOT exceed the maximum amps as listed..
GFCI Receptacle Load Capability
The load capability of the GFCI receptacles is directly
related to the voltage being supplied at either the output
terminals or the two 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
receptacles.
