Emergency shutdown with EPO
The UPS Emergency Power Button is located on the front panel of the UPS and is used for
emergency shutdown in the event of a flood, fire, etc. The EPO circuit breaker immediately
extinguishes the rectifier, inverter and disconnects the UPS output and stops charging or
discharging the battery.
To start the UPS for normal operation after using EPO, restore the emergency stop to its normal
position and supply the UPS voltage. The power supply will start normal operation
automatically.
