It needs to be where it can be accessed easily. It would be sensible to figure out a way to put the breaker right next to the battery, and put them both right next to the Rockwell Automation power distribution block, and put that right next to the fuse panels, to keep wire lengths to a minimum. This will result in less robot weight (#6 wire is heavy), and shorter wires have less electrical resistance, which helps robot performance.
