InstallationConnection of voltage inputsThis concerns the types of Sepam 2000s that havevoltage inputs.Type S26* LT, XT.S36* XR, LR, LS, SS, SR, TR, TS.The phase and residual voltage transformers (VTs)are connected to the CCA 608 8-pin connectoron the 3U/Vo module. Sepam 2000 can functionwith 1, 2 or 3 VTs.The residual voltage can be measured by twomethods:c calculated by Sepam 2000 based on the phasevoltages,c wired directly to Sepam 2000 from a transformerwith broken delta-star windings.SW1 microswitch setting:The microswitches must be set beforethe Sepam 2000 is energized, accordingto the chosen connection diagram.N.B. Sepam 2000 S36 ou S35 TR and TS modelshave two VT connection inputs. Remember to setthe microswitches for both inputs.SONDE ESTOR ESTOR ESB 3U/V0 SONDE212019181716151413121110987654321A8PROBES212019181716151413121110987654321A24-30 48-125 220-250V-DC7INPUTS ANDOUTPUTS212019181716151413121110987654321A624-30 48-125 220-250V-DCINPUTS ANDOUTPUTS212019181716151413121110987654321A524-30 48-125 220-250V-DCINPUTS ANDOUTPUTS87654321ASW14VOLTAGEINPUT212019181716151413121110987654321A3PROBESECMBSW2SW1B654321A2CURRENTINPUT43 +21ACE40B24-30 48-125 220-250V-DC1POWER SUPPLY(communicationoption)* S25, S35 for earlier versions.Connection of 3 VTsThis arrangement does not allow residual voltageto be measured by the sum of the 3 phase voltages.Use the pocket terminal to set the Number parameterof the phase VT ratio heading in the Status menuto 3U.or1233U/V0U21U32U13V2DPCSW1A8A7A6A5A4A3A2A1P1S1P2S2microswitch settingvoltage inputsConnection of 3 VTs (residualvoltage measurement)123This arrangement enables Sepam 2000 to measuresystem voltages and calculate the residual voltagebased on the VT secondary voltages.It requires the use of 3 VTs with the primary betweenphase and earth.
