4.4 EPO 

The  EPO  button  located  in  the  operator  control  and  display  panel  (with  cover  to  avoid 
disoperation, see Fig.4-5) is designed to switch off the UPS in emergency conditions (e.g., fire, 
flood, etc.).To achieve this, just press the EPO button, and the system will turn off the rectifier, 
inverter  and  stop  powering  the  load  immediately  (including  the  inverter  and  bypass  output), 
and the battery stops charging or discharging. 
If the input utility is present, the UPS control circuit will remain active; however, the output will 
be  turned  off.  To  completely  isolate  the  UPS,  users  need  to  open  the  external  mains  input 
supply to the UPS. 
 

  Warning   

When the EPO is triggered, the load is not powered by the UPS. Be careful to use the EPO 
function.
