Warning:
The load for the auto maintenance discharge should be 20%-
100%, if not, the system will not start the process automati-
cally.
8.4. EPO
The EPO button located in the operator control and display
panel (with cover to avoid disoperation, see Fig.55) 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.
