A,
No, you are not in trouble. The rule relates to the fact that the chassis of the Crio and the camera are both tied to the negative power lead of the battery. When these devices are mounted on the frame of the robot, then the frame becomes tied to the negative terminal of the battery. Certain sensors are also wired this way and the KOP sensor boards can contact the frame if not properly mounted. If you are worried then follow the procedure in the link above to find out for sure.
