Introduction 1 The Dellt Tower uninterruptible power system (UPS) protects your sensitive electronic equipment from basic power problems such as power failures, power sags, power surges, brownouts, and line noise. Power outages can occur when you least expect them and power quality can be erratic. These power problems have the potential to corrupt critical data, destroy unsaved work sessions, and damage hardware — causing hours of lost productivity and expensive repairs.
Providing outstanding performance and reliability, the UPS's unique benefits include: S Buck and Boost voltage regulation that ensures regulated voltage to your load by correcting voltage fluctuations. S Start‐on‐battery capability for powering up the UPS even if utility power is not available. S Maintenance is simplified by allowing the safe replacement of batteries without powering down the UPS. S Extended runtime with an optional External Battery Module (EBM) for 1000–1920W UPS models.

8 Troubleshooting The Dell Tower UPS is designed for durable, automatic operation and issues alarms to alert you whenever potential operating problems occur. Usually the alarms shown by the control panel do not mean that the output power is affected. Instead, they are preventive alarms intended to alert the user. Active alarms and active notices are accompanied by an audible buzzer.
Event Log Menu From the Event Log menu, you can access the last 50 events, which includes events, notices, and alarms, arranged from newest to oldest. Events are silent conditions that are recorded in the Event Log as status information, such as “Clock Set Done.” Events do not require a response. Notices and alarms are records of when events occurred and, if applicable, when they were cleared. S Notices, including active notices, are recorded in the Event Log.
