Warning

Only technicians who have been trained in High Voltage Awareness and have completed all required certification courses (if applicable) are permitted to perform this procedure. Proper personal protective equipment (PPE) and insulating HV gloves with a minimum rating of class 0 (1000V) must be worn at all times a high voltage cable, busbar, or fitting is handled. Refer to Tech Note TN-15-92-003, High Voltage Awareness Care Points for additional safety information.

Remove

  1. Drain the coolant from the power conversion system. See Ancillary Bay Coolant (Drain and Refill).
  2. Remove the pyrotechnic battery disconnect. See Pyrotechnic Battery Disconnect (Remove and Replace).
  3. Remove the high voltage controller. See Controller - High Voltage (Non-Structural Pack) (Remove and Replace).
  4. Release the clips that attach the harness to the hinge tray and hinges.
  5. Raise the hinge tray and remove the hinge tray from the hinges.
  6. Cut a slit halfway through 2 absorbent pads and surround each coolant input tube fitting with a pad.
  7. Use the coolant connector removal tool to spread the tube fitting clips wider than the barb on the power conversion system.
