FINAL ASSEMBLY

Once the system is assembled,
close every remaining engineering boundary

The completion of door boards, seals, cables, interfaces, identification, mechanical co-operation and the final closure of environmental boundaries, and the “assembly completion” of large-scale Energy Storage Systems into a truly testable, verifiable and deliverable product state.

Final assembly is not cosmetic finish—it closes engineering boundaries into a verifiable product.

Process integrity and image evidence The end state must be proven.

Image point 01: The front left corner of the cabinet, the door gap and the placard status are recorded.

Release to test area When the mechanical boundary is closed, the system goes into electrical authentication.
