1. Brief introduction--1--1.1 System and model descriptionThis Online Series is an uninterruptible power supply incorporating double-conversiontechnology. It provides perfect protection especially for computer equipment andcommunication systems of computerized instruments.Its true online double-conversion design eliminates all mains power disturbances. A rectifierconverts the alternating current from the utility power to direct current. This direct currentcharges the batteries and powers the inverter. On the basis of the DC voltage, the invertergenerates a pure sinusoidal AC voltage, which is constantly powering the loads.Computers and Peripherals are thus powered entirely by the UPS. In the event of powerfailure, the maintenance-free batteries power the inverter.This manual is designed for the product that the model designation rules as followed:Eaton E Series DX 1000H (X) (XL)Brand nameUPS seriesOutput capacity(VA)Code Batteries internal or externalNil Standard model with batteries internalXL Long backup time model with batteries externalSpecial code means receptacle and plug typeCode Voltage levelH 220-240V~The description followed in this manual is applicable to Eaton DX 10000HXL, DX 15000HXLand DX 20000HXL.This series are three-phase input and single-phase output long backuptime, which are able to connect with the external battery bank.PDF created with pdfFactory Pro trial version www.pdffactory.com
