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 13). To obtain some of the voltages as listed in Table 7 (see below) will require a

ne adjustment using the voltage regulator (VR) control knob located on the control panel.

Voltage Selector Switch

The voltage selector switch (Figure 13) is located above the output terminal panel’s Hard Wire Hook-up Panel. It has been provided for ease of voltage selection.

Generator Amperage

Table 8 shows the maximum amps the generator can provide. DO NOT exceed the maximum amps as listed..

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.

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.

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 2 twist lock auxiliary receptacles.

Table 9 and Table 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.
