    4．Operation 4.1 Operation Modes The UPS is a double-conversion on-line UPS that may operate in the following alternative modes： ◆Normal mode The rectifier/charger derives power from the AC Mains and supplies DC power to the inverter while floating and boosting charge the battery simultaneously. Then, the inverter converts the DC power to AC and supplies to the load.

  • Page 18: Turn On/Off Ups

    ◆ECO Mode When the UPS is at AC Mode and the requirement to the load is not critical, the UPS can be set at ECO mode in order to increase the efficiency of the power supplied. At ECO mode, the UPS works at Line-interactive mode, so the UPS will transfer to bypass supply.
  • Page 19 ◆ Turn ON Bypass breaker(D ual input version ). ◆ Turn ON Input breaker. If the Rectifier input is within voltage range, the rectifier will start up in 30 seconds then the inverter will start up after then. ◆ Turn ON UPS output switch If the rectifier fails at startup, the bypass LED will light up.
