InstallationS811+ Soft Starter MN03900001E—November 2012 19Network Control Terminal BlockThe network control terminal block provides connections D0,D1, and Ground for connection directly to a ModBus system.Additional networks may be accommodated by utilizingcommunications adapters.Typical Control Wiring DiagramsEach diagram illustrates a typical wiring scheme for theoptions described. The additional components shown on thediagrams are not included, but may be purchased fromEaton.Basic Connection Diagram for 3-Wire PushbuttonNotes1. A minimum wire of 14 AWG (2.5 mm2 ) should be usedbetween the 24 Vdc control power supply and thecontrol terminal block.2. See Using an Auxiliary Relay section below if it is desiredto use a relay instead of an indicating lamp for terminals13, 14, 95, 96 and 98.3. 120 Vac may be applied to terminals 13, 14, 95, 96,and 98.4. Add ferrite, Fair-Rite #0446176451 to DC Power Leadsand Control I/O Leads (all through one ferrite) at S811+.5. Functionality of terminals 1, 2, 3, and 4 are shown in thedefault configuration. These terminals are programmablefor other functions. In a 3-wire control system, at leastone terminal must be assigned to a Start command(RUN1) signal.6.
