5. Operating Instructions
5.1 Turning On the UPS
- Ensure the UPS is properly connected to the AC power source and all devices are connected to the UPS output.
- Press and hold the ON button on the front panel for approximately 2 seconds until you hear a beep. The UPS will perform a self-test and then switch to online mode.
5.2 Turning Off the UPS
- If the UPS is in online mode, press and hold the OFF button for approximately 2 seconds until you hear a beep. The UPS will shut down.
- To completely power off the UPS, disconnect the input power cord from the AC outlet after shutting down the unit.
5.3 ECO Mode
The ECO mode allows the UPS to operate with higher efficiency by bypassing the inverter when utility power is stable. This reduces energy consumption and operating costs. Refer to the detailed manual (if provided separately) or the UPS display for instructions on how to enable/disable ECO mode.
5.4 Emergency Power Off (EPO) Function
The EPO function provides an immediate shutdown of the UPS and all connected equipment in an emergency situation. This is typically activated by an external switch connected to the EPO port. Once activated, the UPS will power down instantly. To restart, resolve the emergency condition, then press the ON button.
