12 S611 Soft Starter MN03902011E—May 2012 www.eaton.comTypical Control Wiring DiagramsEach diagram illustrates a typical wiring scheme for the options described. The additionalcomponents shown on the diagrams are not included, but may be purchased from Eaton.Mains power is not required to energize the control circuit of the S611. All protection andoperation parameters may be adjusted using only control power.Compliance with all local, state, and national codes is required if an external 120 Vac powersource other than the normal control power source is used to power the control circuit.Basic Connection Diagram for 120 Vac Three-Wire PushbuttonNotes:1. For a single conductor, a minimum wire of 14 AWG (2.5 mm2) should be used betweenthe control power transformer and the supply terminals.2. See “Using Auxiliary Contacts” section if it is desired to use a relay instead of anindicating lamp for terminals 13, 14, 95, 96 and 98.3. If an isolation or reversing contactor is used upstream of the S611, Eaton recommendsthat the operator uses the level sensing option (default value) of the Start ControlParameter Code in the Advanced Parameters Menu.ResetE-StopMaintainedMomentaryGround+24VD0D1CommonN–TapNeutralL–TapLineStartStopTB1120 VacSupplyUser InterfaceModuleTB4Comms Port A98 97 96 13 14Comms Port BTB5 (Connector)TB2RelaysTB3120 VacControlRelay 2 Relay 1N–NetworkL–NetworkN–PermissiveL–PermissiveN–StartL–StartN–ResetL–Resetwww.comoso.com
