InstallationUse and connection of current inputs to CTs1 A or 5 A CT connectiondiagramThe current transformer (1 A or 5 A) secondarycircuits are connected to the CCA 660 connectoron theECMD module.The connector contains 3 core balance CT primarythroughtadapters to ensure impedance matchingand isolation between the 1 A or 5 A circuits andSepam 2000.The connector may be disconnected with the poweron since disconnection does not open the CT'ssecondary circuit.ESTOR21201918171615141312111098765432124-30 48-125 220-250V-DCAESTOR21201918171615141312111098765432124-30 48-125 220-250V-DCAESTOR ESB ECMDECMDECMDCE4021201918171615141312111098765432124-30 48-125 220-250V-DCA21201918171615141312111098765432124-30 48-125 220-250AV-DCBSW2SW1654321BABSW2SW1654321BABSW2SW1654321BA4321A+B24-30 48-125 220-250V-DC(communicationoption)87654INPUTS AND INPUTS AND INPUTS AND INPUTS AND CURRENTOUPUTS OUTPOUTS OUTPUTS OUTPUTS INPUTSESTOR3 ESTOR2 ESTOR1 ESB WINDING 3(1) (1)(1)Sepam 2000 D31only.3CURRENTINPUTSWINDING 22CURRENTINPUTSWINDING 11POWER SUPPLYECMDPCL1L2L3B4B1B5B2B6B31 2 3CCA 660Sepam 2000 current inputs.Selection of operatingmodes (microswitches)Sepam 2000 has several possible operating modes.The operating mode is selected via microswitches onthe rear of the device.
