Disabled robots moving

This doesn't follow from the robot rules as I read them.

Emphasis mine:

The only other mention of fans in the rules is a limit of a 20A breaker (R48, third row of table), the description of allowed fans (R29, last row: from a KoP, or part of COTS devices).

I can find no rule that requires that a fan ever be switched off apart from a main breaker disable; the rules appear to allow it to be run directly from the output of a PDP breaker, though not quite explicitly.

G1 (generic unsafe operation) is a possibility, but this should have been accompanied with a statement as to why it was unsafe/what had to be corrected. (e.g. a large unshrouded fan is an obvious safety hazard, even if it's behind a motor controller).

Edit: No, it may not be wired directly to the battery; you do have to go through a 20A or smaller breaker per R48.
