Determine whether cables will be routed into Powerwall from either side or
the back of the unit. A conduit fitting or cable gland must be used to seal the entry
into the wiring compartment.
CAUTION
The Powerwall 3 knockouts are not expandable. Do
not drill into the Powerwall 3 enclosure or change any metal
surface for any reason.

The following diagrams provide measurements for:
Positioning conduit entry holes
relative to the Powerwall 3 bracket (the measurements
are the same for both knockouts)
Positioning conduit entry holes
relative to the floor (if mounting Powerwall 3 with its feet at the lowest
height setting and touching the floor)
To open a knockout, position the tip of a slotted screwdriver on
the inner perimeter of the knockout (on the outside of the enclosure). Hammer the
screwdriver to punch out the metal knockout; one well-placed strike is generally
sufficient to dislodge the knockout.
Note
Placing the screwdriver on the inner
perimeter of the knockout rather than the middle allows for the knockout to be
opened with significantly less force.
