4. Installation
4-3
Never use voltage selector switch during operation.
4.3.1 Proper Connection of Three-phase Four-wire Type Terminal
During operation, do not operate voltage selector switch. Voltage
selection during operation may cause abnormal voltage on the load
side to damage the load and may cause a fire.
In addition it could cause damage to generator and automatic
voltage regulator (AVR).
Be sure to shut off generator before using voltage selector switch.
When voltage selection is completed, lock the voltage selector
switch in position to prevent anyone from operating it.
NOTE;
When the voltage selector switch is in the single-phase 240/120V position, place the
ammeter change-over switch to the L1 or L3 position to read the output.
4.3.2 Auxiliary AC Power
In addition to the AC single-phase power from the output
terminals, an auxiliary AC power receptacle panel is provided.
To use these receptacles, place the voltage selector switch to the
single-phase 240/120V position and adjust the output voltage to
240V with the voltage regulator at the generator control panel.
