Under which rule? Just for being unsafe?

R40 very specifically says 24V relative to the negative terminal on the battery, not earth ground, and not the ground of your EL thing.

If there's an isolation transformer, like de_ says, you wouldn't be able to measure any voltage between your robot's negative battery terminal and any point in the EL wiring because your EL thing is completely isolated from the rest of the robot's electrical system. There's no path for current to flow from the EL system to the rest of the robot's electrical system because of that transformer.
