Installation14 S801+ Soft Starter MN03900002E—November 2012 www.eaton.comControl Wiring Terminal BlocksCAUTIONOnly apply 24 Vdc to Control Power Terminal Block. Allcontrol wiring is 22–12 AWG (0.33–2.5 mm 2 ).CAUTIONDo not apply 120 Vac to Control Power Terminal Block.CAUTIONDo not apply 24 Vdc to Network communications TerminalBlock.Terminal Block Wiring CapacityS801+ Control Terminal Block WiringControl Terminal Block—DescriptionsThe S801+ Soft Starter has the following control terminal block control input andaux relay functions:Terminal Block Functions“–“ and “+” Control Power—Connect power supplynegative to pin “–” and to system ground. Connect +24 Vdcoutput to pin “+”. Verify that the 24 Vdc control powersource has the recommended capacity. Minimum controlvoltage is 18 Vdc.Note: To avoid voltage drop during bypass contactor inrush,a minimum of 14 AWG (2.5 mm2) wire should beused between the power supply and the “+” and “–”inputs at the S801+ terminal block.P-Permissive—Control Input 24 Vdc only (maintained).Permissive must be energized (+24 Vdc) to enable START orRUN operation of the unit from any source. If power isremoved from the permissive circuit at any time, the unit willbegin a STOP command. If a soft stop is selected, the softstop will begin and run to time-out.1–START—Control Input 24 Vdc only (momentary input with3 wire control, maintained for 2 wire control). Applying 24 Vdcto terminal 1 while P is energized will initiate a STARTcommand. As shipped from the factory this input is “level”sensitive.2–JOG—Control Input 24 Vdc only (momentary). Input 2 isJOG. Applying 24 Vdc to this input while P is energized willinitiate a JOG. JOG will follow the selected ramp profile aslong as the signal remains present. The unit will not close theinternal bypass contactors.3–Disable OL on Strt—Momentary application of +24 Vdc toTerminal 3 prior to a start raises the overload fault trip pointto 125% of the maximum rating of the frame size for thenext start only.4–RESET—Fault RESET Control Input 24 Vdc only(momentary). Input 4 is Fault RESET. Energizing this inputwill reset a fault only if no active faults are present.Wire SizeNumber ofConductors Torque Requirements22–14 AWG (0.33–2.5 mm2 ) 2 3.5 Lb-in (0.4 Nm)14–12 AWG (2.5–4.0 mm2 ) 1 3.5 Lb-in (0.4 Nm)Position Function Notes“–” 24 Vdc power “–” Power supply negative“+” 24 Vdc power “+” Power supply positiveP Permissive Hardwired STOP command1 Start Hardwired START command2 Jog Jog3 Overload Disable on START4 Reset Fault reset13 Relay, NO contact Changes state when unit achieves internal bypassoperation1495 Fault relay Changes state when unit fault trips9698
