Clarification on R29!

[Crubotics]

R29 The PDP and all circuit breakers must be easily visible for Inspection

The rule in the 2015 Game Manual (Section 4: The Robot) is slightly ambiguous... can anyone elaborate on this?

Does the PDP have to be exposed entirely or can it be covered on all sides but easily revealed for inspection? Does it have to be easily visible during the game on the field for the Refs? Or if it is open for Inspection, can it be covered up for protection during the game?

Thanks,
