Normal Operation
During normal operation, the first line of your LCD Display shows which operating mode your UPS is in: Online, Economy, On Battery, or Bypass.
Online mode: The UPS provides AC power while utility power is available and switches to On Battery mode instantly (zero transfer time) if AC power is interrupted.
Economy mode: The UPS provides AC power at high efficiency while utility power is available and switches to On Battery mode quickly if AC power is interrupted.
On Battery mode: The UPS provides AC power from battery backup so long as battery power lasts. It switches back to Online or Economy mode if utility power is available and shuts down if it runs out of battery power.
Bypass mode: The UPS provides AC power while utility power is available. The UPS shuts down if AC power is interrupted.
The second line of the LCD Display shows basic power conditions. Push the SCROLL buttons to browse through these basic power conditions in the sequence shown below.

On Battery Alarm
When in the On Battery mode, the UPS will beep to inform you that it is using battery power to support connected equipment. If its batteries are at more than half capacity, it will beep every two seconds. If its batteries are below half capacity, it will beep twice a second. If its batteries are nearly depleted, the UPS will beep continuously.
To silence the On Battery Alarm, press the “ON/MUTE” button.
Overload Messages
When the UPS detects an output overload, its LCD will switch to the following display:
OVERLOAD!
LOAD=XXX% X.XXKW
The UPS will then begin a countdown. If the UPS is still overloaded at the end of the countdown, the UPS will automatically go to Bypass Mode to protect its inverter. The duration of the countdown varies with the severity of the overload, as follows:
| Overload Condition | Countdown Duration |
|
| 102% - 125% | 1 minute |
|
| 125% - 150% | 30 seconds |

| >150% | Immediate |
