Why did my load drop when running a self-test?

In extreme cases, running the self-test could cause the UPS to shut down. On select models, a certain voltage range is required to maintain power to the unit. During the self-test, if voltage drops to an unusable range, the UPS could shut down. In order to avoid this, you should run a self-test at least once a month to detect a battery needing replacement. Please reference your owner’s manual for more information on how to perform a self-test on your unit.
