Close Wiring Compartments

  1. Before closing any installed hardware, take photos of the completed wiring in the Powerwall, Backup Switch, and main distribution board.
  2. Inspect the AC and PV wiring terminals to ensure all wire strands are properly inserted.
  3. Ensure that all conduit junctions and cable entry points are secure and properly sealed.
  4. Arrange all wires neatly inside the Powerwall wiring compartment.
  5. Install the air intake screen over the opening at the bottom of Powerwall, ensuring it snaps into place.
  6. Clean the front edge of the Powerwall enclosure with a microfiber cloth to remove any debris that might interfere with the seal.
  7. Carefully remove the glass front cover from its packaging and, using a microfiber cloth, clean the sealing gasket around the edge of the front cover to remove any debris that might interfere with the seal.

    CAUTION
    Take extreme care when handling the sealing gasket. Damage to or contamination of the gasket or its mating surface could compromise Powerwall's ingress protection, resulting in product damage.
  8. Carefully install the glass front cover:
    1. Align the lower mounting tabs with the two alignment shelves in the enclosure (A).
    2. Rotate the front cover toward the enclosure to engage the top mounting tabs with the enclosure (B). Maintain pressure (15-20 lb force) on the front of the cover to compress the sealing gasket.

      CAUTION
      Maintain pressure to keep the sealing gasket compressed until all fasteners are installed and tightened. If the sealing gasket is not compressed, the fasteners may thread form in the enclosure, breaking the front cover mounting tabs.
    3. Install and tighten the top (2X) T20 fasteners in the fastener slots (C).

      Note
      T20 fasteners (Tesla P/N 1847553-00-A) are included in the accessory bag:
      • Early revisions of the fasteners (left, below) are single use; to reuse these fasteners, remove the black gasket from the fastener (①)
      • Later revisions of the fasteners (right, below) do not include a gasket and can be reused without any alteration
      The gasket is not required and does not impact the enclosure rating of Powerwall 3.
    4. Install and tighten the remaining (4X) T20 fasteners in the fastener slots on the sides of the unit (D).
    5. Tighten each fastener to approximately 25 in-lb (2.8 Nm) or hand-tight.

      CAUTION
      Do not use an impact driver to torque the fasteners.
  9. Clearly label all circuit breakers.
