4. Run the 4-conductor communication cable, the high-voltage AC conductors and high-
voltage grounding conductor through the conduit or cable gland and pull them into the
Powerwall wiring compartment.
5. Run the other end of the 4-conductor communication cable, the high-voltage AC
conductors and high-voltage grounding conductor into the Backup Gateway enclosure.
6. On the Backup Gateway side, strip the end of the high-voltage grounding conductor and
insert it in the ground bar in the Backup Gateway enclosure (Fig 35). The ground bar is
identified with the following symbol:
in).
7. On the Powerwall side, strip the end of the high-voltage grounding conductor and insert it in
the Powerwall chassis ground lug (Fig 36). The ground lug is identified with the following
symbol: . Tighten the screw in the ground lug to 4.5 Nm (40 lb-in).
8. On each end of the 4-conductor communication cable, strip and insert the wires into the
provided 4-pin Phoenix connectors according to the following table and diagram (Fig. 34). On
the Powerwall side, use the black Phoenix connector.
