Step 12. Close the Wiring Compartments and Turn On the System

1. Before closing any installed hardware, take photos of the completed wiring in the
Powerwall, Gateway, and main switchboard.
2. Ensure that all conduit or cable gland junctions and cable entry points are secure and
properly sealed.
3. Arrange the communication and AC power wires inside the Powerwall wiring compartment.
4. Replace the cover on the Powerwall wiring compartment. Ensure that the cover seats
properly on the gasket so that the compartment is sealed. Using the provided Torx T20 bit,
tighten the fasteners to 1.5 Nm.
5. Replace the left side cover on Powerwall by pushing the top into place and working toward
the bottom to reattach it to the clips along the length of the unit.
6. Replace the Backup Gateway dead front panel and secure it firmly with the original screw.
Remount the Backup Gateway door, and latch it shut.
NOTE: If the Backup Gateway is installed outdoors or in a high-traffic area, the latch can be
locked or zip-tied shut.
7. Switch on the AC circuit breakers for the Backup Gateway and Powerwall.
8. Switch on Powerwall by moving the switch on the right side of the unit to the ON position.
When Powerwall establishes communication with the Backup Gateway, the LED on the right
side of Powerwall illuminates.
