  3. Use IPA wipes to clean the HV connector contact surface and the busbar HV connector contact surface of the residual Penetrox. Allow one minute of drying time for each surface.
    Informational PurposesAn informational icon, calling your attention
    Note
    A new busbar comes with Penetrox pre-applied to the HV connector; clean the contact surface of the busbar HV connector when reusing a busbar.
  4. Apply Penetrox onto the HV connector joints. Apply 2 drops of Penetrox A-13 (about 5mm in diameter) on each side of the hole on both leads, and spread evenly to ensure full coverage of the contact surface.
  5. Remove the inflatable air bag from under the HV header.
  6. Position the busbar kit connector, lower it onto the HV header while lifting the rear end of the busbar assembly to ease installation.
