4.4 EPO
The EPO button located in the operator control and display panel (with cover to avoid disoperation,
see Figure4-5) 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), 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 turn off the external mains input
supply to the UPS. Users can restart the UPS by powering the UPS again.
Warning
When the EPO is triggered, the load is not powered by the UPS. Be careful to use the EPO
function.
