From the Manual, in the blue box after R07-A:


Under Rule <R07-A> whenever the ROBOT is on a flat floor, the BUMPERS must remain entirely within the BUMPER ZONE. But when the ROBOT is driving over a BUMP or RAMP and/or ELEVATED or SUSPENDED (or in the process of being ELEVATED or SUSPENDED) on the TOWER
• it is no longer constrained by Rule <R07-A>, and
• it is expected and allowed that the BUMPERS will travel outside (typically above) the BUMPER ZONE, and
• if the ROBOT is "frozen" (i.e. all moving parts halted) and placed on a flat surface, the BUMPERS do not have to be within the BUMPER ZONE.
Note that these effects are only in force when the ROBOT is actually driving over the BUMP or RAMP and/or ELEVATED or SUSPENDED (or in the process of being ELEVATED or SUSPENDED) on the TOWER (i.e. the body of the ROBOT must not be in its normal flat-floor attitude and elevation). Simply touching the BUMP, RAMP, or TOWER is not a sufficient condition to avoid violating Rule <R07-A>.
