On line UPS Systems

In this Ups  there are two  switches  one is  main static switch  and another  is Ups  static  switch . in normal  operation the Ups  static switch  remains on. It will be off  if UPS  systems  fails. In  this  condition the main  switch  is used to bypass  the UPS.  The main  static  normally  remains OFF.
