Powerwall 3 ships with (6) clamp-on ferrite
cores for AC wiring and the Powerwall Protective Earth. Additional ferrite cores are
factory-installed for the PV wiring and the Tesla Asset Controller (TACO) low voltage
harness.
CAUTION
Ferrite cores are
fragile; handle with caution.
CAUTION
Ensure all conductors
have been stripped properly so that no live conductors come in contact with the ferrite
cores.
Note
All ferrite cores provided with Powerwall 3 are split core; they can be opened
to be placed around the conductor(s) rather than threading them over the
conductor(s).
Install the small square clamp-on ferrite
core around the TACO factory-installed harness.
Note
If the ferrite core has already
been installed by the factory, skip this step. If the accessory bag contains an
additional small square ferrite core when there is already one installed on the
harness, the extra ferrite core can be recycled or saved as a spare.
Install (1) of the medium clamp-on ferrite cores
around L1 and N. Ensure the ferrite core is as close to the AC connector as possible
without bending or deforming the wires.
Install (1) of the medium clamp-on ferrite cores
around L1, N, and the Protective Earth.
Install the (1) small clamp-on ferrite core around the Protective Earth.
Install the (2) marked (with pink sticker)
medium clamp-on ferrite cores around L1 and N in the top of the wiring
compartment.
Secure all ferrite cores closed with
the provided cable ties.

and Protective Earth
Note
Ensure the ferrite cores are installed
as described here; for instance, do not clamp a ferrite core around only L1 or N when it
is required to be clamped around both L1 and N:
