6 | Introduction Introduction The Dell t Line-Interactive Rack 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.
7 Introduction | 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.
8 | Introduction Finding Information CAUTION: The Safety, Environmental, and Regulatory Information document provides important safety and regulatory information.
9 Safety Warnings | Safety Warnings CAUTION: Before performing the procedures in this document, read and follow the safety instructions and important regulatory information in your Safety, Environmental, and Regulatory Information document.
10 | Safety Warnings S Unpacking the cabinet in a low-temperature environment may cause condensation to occur in and on the cabinet. Do not install the cabinet until the inside and outside of the cabinet are absolutely dry (hazard of electric shock).
11 Safety Warnings | WARNING: Additional instructions for Rack-Mounted Systems S Your rack kit has been approved only for the rack cabinet provided. It is your responsibility to ensure that installation of the equipment into any other rack complies with all applicable standards.
