S611 Soft Starter MN03902011E—May 2012 www.eaton.com 15120 Vac 50/60 Hz Control PowerThe S611 soft starter requires 120 Vac 50/60 Hz controlpower. The sealed in and inrush characteristics of the S611soft starter are summarized in the table below:Control Power RequirementsFor applications where one starter is used with one controlpower transformer (CPT), the CPT selected must be equal toor greater than both the sealed in and inrush requirements ofthe starters.● Max steady state for the CPT * sealed in power of thestarter● Outrush for the CPT * inrush power of the starterMultiple starters can be used with one CPT. If the applicationrequires the starters to start at the same time, the CPT mustbe sized for the sum of the sealed in and inrush power foreach starter.● Max steady state for the CPT * sum of the sealed in powerof all the starters● Outrush for the CPT * sum of the inrush power of all thestartersFormulas to calculate control power requirements are asfollows:● Definitions:● SI = Sum of seal incurrent● LS = Largest seal incurrent● LI = Largest inrush needed● TS = Total seal incurrent needed● LO = Largest outrush needed● TS = (SI – LS)LO = TS + LI● Max steady state for the CPT * SI● Outrush for the CPT * LOThe voltage on the S611 control power supply and controlinput terminals must be 120 Vac ±10% to provide properoperation of the soft starter.Control Wiring Application NotesCAUTIONOnly apply 120 Vac 50/60 Hz to terminal blocks TB1, TB2,and TB3. All control wiring is 22–12 AWG (0.33–2.5 mm2).Failure to follow this caution may result in damage to thecontrol circuit.1. Connect 120 Vac supply neutral to Neutral terminal,using a minimum wire of 14 AWG (2.5 mm2).2. Connect 120 Vac line to Line terminal, using a minimumwire of 14 AWG (2.5 mm2).Connecting a New or ReplacementUser Interface Module (UI)The S611 uses the User Interface Module (UI) to change theconfiguration of operating parameters with a display toindicate values and fault codes. By entering parameterchanges, parameter information is stored on the S611printed circuit board. By default, the UI may be removed atany time.The S611 may be configured to fault if the user interfacemodule is removed for any reason.Soft StarterFrameSealed Inrush Duration(ms)VA Watts VA WattsA 85 60 600 420 50B 85 60 600 420 50C 85 60 600 420 50D 85 60 600 420 50E 115 80 1200 840 50F 115 80 1200 840 50www.comoso.com
