Power cable wires don't match instructions

Vertex 3D Printer Vertex - Assembly and user manual

I’m at step 14 of the instructions, and about to attach the power cable, but the colors of my cable do not match the colors in the instructions.

The instructions reference BROWN, BLUE, and GREEN wires, but mine are WHITE, BLACK, and GREEN.

I’m not sure how to wire this in correctly, has anyone else seen this?

I found this, hopefully it helps someone else who has the same thing:
