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.

knockout.
