Required Supplies; Step 1. Plan The Installation Site - Tesla Powerwall 2 AC Installation Manual

Required Supplies

•
Mounting bracket hardware (see "Step 3: Anchor the Powerwall Mounting Bracket")
• Conduit fitting or cable gland (depending on local electrical requirements)
• Conduit or raceway (depending on local electrical requirements)
• Minimum 300 V rated 4-conductor or double-insulated (with one twisted pair) shielded copper
(Cu) cable (for communication connection between Powerwall and the Backup Gateway)
• Minimum 600 V, 90 deg C rated copper (Cu) cable (for power connections to Powerwall and the
Backup Gateway)
• Siemens HS-style conduit hub (for sealed entry into the top of the Backup Gateway enclosure)

Step 1. Plan the Installation Site

The installation location for Powerwall must accommodate placement of the Backup Gateway
and meet all conditions described above in "Site Requirements." In addition, consider the
following points when choosing where to install Powerwall.
Wall mounting: Choose a wall capable of supporting the full weight of Powerwall, with one of
the following characteristics: wood studs at regular intervals, plywood sheeting of sufficient
thickness, solid concrete or masonry, or metal studs of sufficient gauge.
Floor mounting: Choose a level surface adjacent to a wall space that meets all the
requirements for wall mounting described above. Make sure the area is isolated from hazards
that may damage the unit, such as vehicle traffic or flooding.
Cable entry: Determine whether cables will be routed into Powerwall from the side or from the
back of the unit. With side cable entry, a conduit fitting or cable gland must be used to seal
the entry into the wiring compartment. With back cable entry, a wire cover should be used to
seal the entry into the wiring compartment.
NOTE: If Powerwall is mounted on a wall with studs spaced 24 in (610 mm) apart, cable entry
from the back of Powerwall may be blocked.
Backup Gateway configuration: Determine whether cable entry into the Backup Gateway will
be from the top, bottom, or side. (Optional: when cable entry is from the bottom half of the
enclosure, the back panel of the unit may be rotated 180 degrees to simplify cable runs.)
NOTE: For cable entry at the top of the Backup Gateway enclosure, an HS-style hub should be
used in order to maintain enclosure ingress protection.
Electrical service connection: The Backup Gateway is service entrance rated, and can be
located between the main switch and the switchboard.
