Remove and Install the Power Module Current Sensors for Frames 8...15

Replace the power module current sensors with the appropriate kit catalog number:
  • SK-RM-INVCS1-F8M, 622 A (compatible with power module catalog numbers 20-750-MIn-C302D302, 20-750-MIn-C367D361, 20-750-MIn-C460D430, 20-750-MIn-C540D505, and all 20-750-MIn-EnnnFnnn)
  • SK-RM-INVCS2-F8M, 1000 A (compatible with power module catalog numbers 20-750-MIn-C585D545, 20-750-MIn-C650D617, 20-750-MIn-C750D710, and 20-750-MIn-C770D740)
Follow these steps to remove and install the current sensors.
  1. Review the product advisories in Before You Begin.
  2. Remove power from the system.
  3. Open the corresponding enclosure door.
  4. Remove the power module from the enclosure.
  5. Remove the circuit board tray from the power module.
  6. Remove the six M8 x 20 mm Torx screws that secure the three flexible bus cables to the IGBT power terminals and pull the flexible bus cables through the opening in the current sensors.
  7. Remove the six M4 x 10 mm Torx screws that secure the three current sensors to the power module chassis and remove the current sensors.
