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.
