InstallationConnection of power supply and logic inputs and outputsConnection of powersupply and earthThe Sepam 2000 power supply is connected to theCCA 604 4-point terminal block on the CE40 modulesituated on the rear of the device.The power supply input is protected againstaccidental polarity inversion.Safety:The Sepam 2000 chassis must beearthed via the grounding screwsituated on the right side panel(rear view).Use a braid or cable fitted with a 4 mm eye lug.The eye lug fastening screw is already mountedon Sepam 2000 when it is delivered.(Should this screw be lost, never replace it by ascrew longer than 8mm).ESTOR21201918171615141312111098765432124-30 48-125 220-250V-DCAESTOR21201918171615141312111098765432124-30 48-125 220-250V-DCA87654INPUTS AND INPUTS AND INPUTS AND INPUTS AND CURRENTOUPUTS OUTPOUTS OUTPUTS OUTPUTS INPUTSESTOR3 ESTOR2 ESTOR1 ESB WINDING 3(1) (1)(1)Sepam 2000 D31onlyESTOR ESB ECMDECMDECMDCE4021201918171615141312111098765432124-30 48-125 220-250V-DCA21201918171615141312111098765432124-30 48-125 220-250AV-DCBSW2SW1654321BASW13BSW2654321BACURRENTINPUTSWINDING 2BSW2SW1654321BA2CURRENTINPUTSWINDING 14321A+1POWER SUPPLYB24-30 48-125 220-250V-DC(communicationoption)Connection of logic inputsand outputsThe logical data are connected to the CCA 621connector on the ESB and ESTOR modules.Check that the voltage applied to the inputs iscompatible with the permissible voltage indicatedby a dot on the subassembly.Cabling should be done in accordance withthe diagram given in the technical manual foryour Sepam (Sepam 2000 D22 or Sepam 2000D21 - D31).ESBCDGO2O1l2l1DPCAA21A20A19A18A17A16A15A14A13A12A11A10A9A8A7A6A5A4A3A2A1ESTORl18l17l16l15l14l13O14O13O12O11l12l11DPCAA21A20A19A18A17A16A15A14A13A12A11A10A9A8A7A6A5A4A3A2A1ESTOR21201918171615141312111098765432124-30 48-125 220-250V-DCAESTOR21201918171615141312111098765432124-30 48-125 220-250V-DC87654INPUTS AND INPUTS AND INPUTS AND INPUTS AND CURRENTOUPUTS OUTPOUTS OUTPUTS OUTPUTS INPUTSESTOR3 ESTOR2 ESTOR1 ESB WINDING 3(1) (1)(1)Sepam 2000 D31onlyAESTOR ESB ECMDECMDECMDCE4021201918171615141312111098765432124-30 48-125 220-250V-DCA21201918171615141312111098765432124-30 48-125 220-250AV-DCBSW2SW1654321BASW13BSW2654321BACURRENTINPUTSWINDING 2BSW2SW1654321BA2CURRENTINPUTSWINDING 14321A+1POWER SUPPLYB24-30 48-125 220-250V-DC(communicationoption)Example : ESTOR and ESB1/12D21 - D22 - D31 - Installation - Use - Commissioning
