eUpsMode : The eUpsMode defines whether persistent data are to be written and whether a quick shutdown
is to be performed. Standard value is eSUPS_WrPersistData_Shutdown, i.e. with writing of the persistent
data and then quick shutdown. (Type:
E_S_UPS_Mode [

shutdown. The tRecoverTime must be somewhat longer than the maximum holding time of the UPS, since
the UPS switches off even when the voltage returns
