The load is supplied with AC power but not protected
in ECO mode.
2. If Bypass AC source not available:
LED is ON.
The audio alarm sounds intermittently.
The load is automatically supplied in Normal
mode via the Normal AC input.
3. Both Normal and Bypass AC sources not
available or out of tolerance:
LED is ON.
LED is ON.
The audio alarm sounds intermittently.
The load is powered by the battery power from the
UPS.
The display indicates the battery remaining
backup time.
