0 About this Manual0.6 Abbreviations8 DS7 Soft starter 09/16 MN03901001Z-EN www.eaton.com0.6 AbbreviationsThe following abbreviations are used in this manual:0.7 Mains supply voltagesThe rated operating voltages stated in the following table are based on thestandard values.In ring networks (as found in Europe) the rated operating voltage at thetransfer point of the power supply companies is the same as the value in theconsumer networks (e.g. 230 V or 400 V).In star networks (as found in North America), the rated operating voltage atthe transfer point of the utility companies is higher than in the consumernetwork.Example: 120 V → 115 V, 240 V → 230 V, 480 V → 460 V.The wide tolerance range of the DS7 soft starters allows for voltage drops of10% and a voltage drop of additional 4 %, as well as an excess voltage of10 % that are permissible in consumer supply networks.The rated mains voltage operational data is always based on mainsfrequencies of 50/60 Hz (50 Hz - 5 % – 60 Hz +5 %).Abbreviation MeaningBG Construction sizeDS Default settingsDS7-SWD DS7 soft starter with SmartWire-DT(abbreviated designation for devices with part no.
