Remove and Install the LCL Filter Capacitor Assembly for Frames 8...15

Replace the LCL filter module capacitor assembly with the appropriate kit catalog number based on the installed LCL filter that is identified in this table. Each LCL filter module capacitor assembly kit contains one capacitor. It is recommended that you replace all capacitors in the module.

Follow these steps to remove and install the LCL filter capacitor assembly.
  1. Review the product advisories in Before You Begin.
  2. Remove power from the system.
  3. Open the corresponding power bay enclosure door.
  4. Remove the LCL filter module from the enclosure.
  5. Remove the wire access cover to more easily feed the wiring through the back of the chassis when a capacitor assembly is removed. Remove the eight M4 x 10 mm Torx screws that secure the capacitor wire access cover to the chassis and remove the cover.

  6. IMPORTANT: The interconnection wires cannot be removed from the terminal block on the top of the capacitor until the capacitor assembly has been removed from the chassis.
  7. For each capacitor in the LCL filter module, complete these steps:
    1. Loosen, but do not remove, the upper two M6 x 16 mm Torx screws that secure the capacitor assembly to the chassis.
    2. Remove the lower two M6 x 16 mm Torx screws that secure the capacitor assembly to the chassis.
    3. Lift the capacitor assembly up and off the top screws and slide the assembly out of the chassis.
    4. Disconnect the wires from terminals at the top of the capacitor and remove the capacitor assembly.

  8. TIP: The contents of the capacitor canisters is classified as not hazardous according to regulation (EC) 1272/2008 [CLP] and classified as not dangerous according to 76/548/ EEC / 1999/24/EEC.
  9. Install the LCL filter capacitor assembly in the reverse order of removal. Verify that the wire harness connections that route through the R, S and T current sensors connect to the correct terminal on the capacitor R, S and T.
