InstallationReplacement of Sepam 2000 D01 and Sepam 2000 D22Sepam 2000 D01 and D02 units may be replaced by a Sepam D22. The followingprecautions must be taken during the replacement operation.AssemblyThe sizes and drilling dimensions are the same regardless of the type of Sepam2000 used.Connection of phase inputsThe CCA 651 phase current input connectors may be kept or replaced by CCA 660connectors.Connection of neutral point current inputsIt is only necessary to connect the neutral point current inputs for the use of theF65 restricted earth fault protection.Other connectionsThey are all the same unless the control logic has been customized.Sepam 2000 D22 settingsprotectiontransformer differential (F601)restricted earth fault (F651)parametercontrol logictime delayparameterstatusrated frequencyCT ratioCT' ratioIo' sensortransformerdisturbance recordingcommunicationtime-taggingId/It = unchangedsetting unchangedsettings unchangedsettings unchangedsettings unchangedsetting unchangedthe setting is limited to the In and In' setting(CT rating)any setting for a D01setting unchanged for a D02S : transformer powerUn : rated voltage of winding 1 connectedto the ECMD2 boardUn' : rated voltage of winding 1 connectedto the ECMD2 boardIndex' : vector group of winding 2 comparedto winding 1setting to be defined according to operationavailable as of version 9940 SFT 2800for earlier versions, pretrig 9 is equal to 24periodssettings unchangedsettings unchangedCommunicationGiven the change of application, access to the settings by remote reading isdifferent for the following functions:functionsdifferencesdifférential transformer the function number is 60 instead of 59the number of settings is reduced from 3 to 1CT ratio the number of settings is reduced from 3 to 1CT' ratiotransformernew function with 4 settingsdisturbance recordingaccess to the setting prétrig1/14D21 - D22 - D31 - Installation - Use - Commissioning
