4-Position Voltage Selector Switch (Optional) - Magnum MMG25FHZ Operating Manual

4-POSITION VOLTAGE SELECTOR SWITCH (OPTIONAL)

The voltage selector switch is located under the control panel, next to the connection lugs. This optional selector
switch is a four position switch that mechanically changes the connection between the generator output leads and
the connection lugs or optional cam lock connectors. Voltage ranges are selected by rotating the handle on the switch
to the desired voltage.
NEVER attempt to change the voltage selector switch while the engine is running! This will
cause severe arcing and damage to the switch and generator windings.
The connection lug door is equipped with safety interlock switches that will trip the main circuit breaker and disable
the voltage regulator, dropping the operator output to residual voltage, if the door is opened while the unit is operating.
Never attempt to disable or modify the lug door safety switches. Equipment damage,
Note: (The following applies to units without a convenience outlet buck transformer.) When the voltage selector
switch is in position for 480/277V 3Ø, voltage at the two GFCI duplex convenience outlets is 139 Volts, and the
voltage at the two twist-lock convenience outlets is 240/139 Volts. When the voltage selector switch is in position for
208/120V 3Ø, voltage at the two GFCI duplex convenience outlets is 120 Volts, and the voltage at the two twist-lock
convenience outlets is 208/120 Volts. When the voltage selector switch is in position for 120/240 3Ø (DELTA), voltage
at the two GFCI duplex convenience outlets is 120 Volts, and the two TWIST-LOCK OUTLETS SHOULD NOT BE
USED. When the voltage selector switch is in position for 120/240V 1Ø, voltage at the two GFCI duplex convenience
outlets is 120 Volts, and the voltage at the two twist-lock outlets is 120/240 Volts.
