Installation ‐ Power Wiring(100A model and above)Technical Manual: Smartstart® 6000 IMI0042 rev KPage 12Relocating the Internal CurrentTransformers for 6 wire operation.The Smartstart® 6000 comes standard with internalCurrent Transformers (C.T’s) for monitoring thecurrent during acceleration, deceleration and when inbypass.It is important that the Smartstart ® 6000 be wired in amanner to ensure the C.T’s are always monitoring themotor current. For this reason 9 terminals areprovided. This is important to ensure continualprotection of the soft starter, the motor and the load.The correct installation of the C.T’s is crucial foroptimum performance of the torque control system.In 6 wire operation, it is necessary to relocate the C.T’sexternal to the starter. For 6 wire operation the C.T’sare to be installed on the incoming line supply cablesso that the line current is monitored (not the phasecurrents).The Smartstart® 6000 must be purchased with C.T’sexternal by ordering ‘prepared for 6 wire’;Part no. Description:TF60015 Prepare for 6 wire: 6R100‐220TF60016 Prepare for 6 wire: 6R360‐830NOTE: 6 Wire using Internal CT’sIn some cases the CT’s may remain internal. This is subjectto the Motor FLC and the Soft Starter Rating. Refer toAppendix E Page 52 for more details.Installation of external C.T’sWhen relocating the C.T’s external to the soft starter itis important to ensure the following:1. C.T’s are installed on L1 & L32. C.T’s are installed in correct directionP1 label = line side3. C.T’s are terminated with correct phasing.S1 = RedS2 = BlackThe C.T’s supplied with the Smartstart ®6000 has alabel which shows the correct phase and direction.If the C.T’s are not installed correctly the starter willdisplay a fault or a ‘C.T Phase error’.Programming:Program the starter for 3wire or 6 wire operation. Theselection available for 6 wire is ‘Standard 6 wire’ or‘alternate 6 wire’, depending on the wiringconfiguration used. The wiring in this manual is drawnfor Standard 6 wire. Refer to page 21: parameter ‘M04Motor Wiring’.Energise the 3 Phase supply to the starter withoutattempting a start. Look for a “W05 MOTOR WIRING”warning and check the “MTR WIRING CHK” is‘CORRECT’ in the diagnostic menu.Check for correct installationThe Correct CT connection can be checked after thefirst motor start. A CT phase error may be identifiedunder the menu ‘Starter Diagnosis’. ‘+L1 / +L3’ shouldbe displayed.> If L2 is displayed move the CT from L2 phase.> If a “‐“sign is displayed, the direction of thecorresponding CT needs to be reversed.Incorrect CT installation will result in a “W07 CTPHASING” warning and affect the optimum starting ofthe motor.
