A040159-1

A040160-1

A040141

During operation, do not operate the 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 the generator before using the voltage selector 
switch.

When voltage selection is completed, lock the voltage selector 
switch in position to prevent anyone from operating it.
