Modes of  Operation 

There are three operation modes, which differ in the path of the energy flow. 
UPS block diagrams and the energy flow path in each operation mode is shown below: 

 

When UPS has no separate bypass mains input, bypass line is also fed from the mains input. Thus, if such 

a device is in question, mains input shall be comprehended when the bypass mains input is referred in the 

following sections of the manual.  
UPS behavior at the start-up is different from the usual operation. The UPS can only operate in bypass 

mode during start-up. So, in order for the UPS to start-up, frequency/waveform/rms value of the bypass 

mains voltage shall be in acceptable limits and bypass shall be enabled.
