6.5. EPO.
The EPO button is located on the control panel and has the
function of turning off the UPS in emergency conditions (e.g.,
fire, flood, etc.). The EPO button has a protection to prevent
accidental activation, see Fig. 54.
When the button is pressed, the system will turn off the rectifier
and inverter, stop powering the load immediately (including
the inverter and bypass) and the battery will stop charging or
discharging.
If there is an input mains, the UPS’s control circuit will continue
to be activated but the output will turn off. To completely
isolate the UPS, disconnect the mains power input. To restart
the UPS, reconnect it.
When the EPO is tripped, the load stops being powered
by the UPS. Pay attention when using the EPO function.
