13mm hex wrench
Torque wrench
Steps
  1. Perform a lockout on the powertrain.
  2. Verify the controller is fully de-energized.
  3. Disconnect the AMPSeal 34-pin connector at the front/head of the controller to disable its operation.
  4. Remove the power terminal bolts with the 13mm hex wrench.
    Warning Warning: Perform this operation as gently as possible, since the bolts conduct full powertrain current and are torqued low-spec at 12ft-lbs.
    Immediately cover the cable leads in a strong insulative sleeve to ensure that nothing conductive contacts them.
    Consider arc-over risks beyond simple contact if the system were energized for any reason.
    Warning Warning: Safe cover specifications for these leads is not yet determined. Arc flash can be lethal or destructive to equipment.
  5. Unbolt the controller from the frame's tail horns.
