Tesla Model 3: DC Input Assembly - HV Battery- Install
Install
- Install the DC input assembly to the penthouse, install the bolts (x4)
that attach the DC input assembly to the penthouse, and then mark the bolts
with a paint pen after they are torqued.
Torque 6 Nm
- Install new bolts (x2) to attach the DC input busbars to the fast charge
contactor busbars, and then mark the bolts with a paint pen after they are
torqued.
Torque 9 Nm

- Use the Hioki resistance meter to measure the resistance at the HV joint
between the positive DC input busbar and the positive (LH) fast charge
contactor busbar.
Note: The maximum acceptable resistance is 0.060 mΩ (60 μΩ). If the
resistance is above this value, escalate a Toolbox session, as appropriate.

- Use the Hioki resistance meter to measure the resistance at the HV joint
between the negative DC input busbar and the negative (RH) fast charge
contactor busbar.
Note: The maximum acceptable resistance is 0.060 mΩ (60 μΩ). If the
resistance is above this value, escalate a Toolbox session, as appropriate.
- Install the insulator for the DC input assembly.
- Connect the electrical harness to the DC input assembly connector.
- Install the pyrotechnic battery disconnect into the penthouse. See
Pyrotechnic Battery Disconnect (Remove and Replace).
