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 Bypass

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.
