4.7 Remote Emergency Power Off (REPO)
REPO turns off the UPS in case of any emergency conditions. In case of emergency, the REPO switch turns off the rectifier
and inverter and stops powering the load immediately. The battery stops charging and discharging.
To manually power off in an emergency, disconnect the terminal connecting the REPO port on the rear of the UPS.
If mains/utility power is connected to the UPS input, the UPS control circuit remains active even though output power is
disabled. To remove all mains/utility power, disconnect the external main input circuit breaker.
