On Battery Alarm
When in the On Battery Mode, the UPS power module will beep to inform you that it is using battery power to support
connected equipment. If its connected batteries are at more than half capacity, it will beep every two seconds. If its
connected batteries are below half capacity, it will beep twice a second. If its connected batteries are nearly depleted, the
UPS power module 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:
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
106% - 125%
1 minute
126% - 150%
30 seconds
>150%
Immediate
Bypass Messages
While in Bypass Mode, the UPS monitors its input voltage and passes that input power along to connected equipment. The UPS
will not provide battery backup in Bypass Mode.
If the output voltage deviates from an acceptable range (between 15% higher and 20% lower than nominal), the UPS
displays the condition on its LCD and stops supplying output power to its load. If power levels return to an acceptable level,
the UPS resumes supplying power to the load, and its LCD reports that output voltage was too high or too low at one time,
but has returned to nominal.
