3.3  Input Voltage Range Selection 
WARNING:  Voltages up to 360 VDC and 270 VAC are present in certain sections of 
this power source.  This equipment generates potentially lethal voltages. 
 
DEATH:  On contact may result if personnel fail to observe safety precautions.  Do 
not touch electric circuits when power is applied.  Servicing should only
