12. Troubleshooting In the event of an observed failure or unexpected behavior, first check external factors that may impact UPS system functionality (e.g., environmental conditions such as excessive temperature or humidity, installation or site changes with cabling). Additionally, ensure all breakers are switched to the "On" position. Section 9.4 Text Summaries and Explanations includes the list of event notifications that may be displayed in the Events screen, including those for many external factors. If there are no events displayed and the behavior is not shown in the events notifications or the table below, contact Tripp Lite Technical Support.
