Remove and Install the LCL Filter Capacitor - Frame 5

Replace an LCL filter capacitor with one of the following kit catalog numbers:
  • SK-RM-LCLCP4-F5 (400V/480V, 30 kW/40 Hp and higher)
  • SK-RM-LCLCP6-F5 (400V/480V, 22 kW/30 Hp and lower, and all 600V/690V)
Follow these steps to remove and install the LCL filter capacitor.
  1. Review the product advisories in Before You Begin.
  2. Remove power from the system.
  3. Remove the cover from the chassis. See Remove and Install the Frame 5 Cover.
  4. Loosen the M5 hexagonal screws that secure the capacitor wires to terminals R, S and T on the capacitor terminal block at the top of the cap, and remove the wires.
  5. Remove the M12 hex nut that secures the capacitor to the mounting bracket.
  6. Cut the cable tie (A) that secures the capacitor to the bracket, and remove the capacitor.

  8. If the pad is damaged, remove the existing pad material and clean the surface of the chassis with a 50% isopropyl alcohol and 50% water solution.
  9. Install the new foam pad that is provided with the kit.
  10. Insert the three legs of the resistor (C) that is supplied with the kit into the terminal block at the top of the capacitor and secure the resistor.
