I believe you are reading it correctly as "Do Not Hump".
I believe "Hump" is a railway term. I'm no expert in this but my guess is
that it refers to a humping yard where trains are sorted by pushing cars
over a hump, after which they gravity roll down a gentle incline and get
switched onto the appropriate siding so as to become part of the train
heading to it's intended destination.
The incline has to be steep enough so that a poor running car will roll, so
the really smooth running cars can build up enough speed to cause damage
when it meets the stationary train. It may be undesirable to take this risk
with a payload so one would advise the railway to not sort using a humping
yard.
But then, I could be all wrong.
