I've found both of the above comments to be correct. Last year I moved from Alaska in the dead of winter. The temperature was -15 F when everything was packed into a steel box which went by barge to Seattle, then trucked to up-state New York.
All of the components were given a day in their new home to thaw, I checked closely for condensation, plugged them in, and had no problems.
