Tiltwatch Question

You must ask this question of the manufacturer, that is the only useful answer. Those devices are used to indicate that the equipment has possibly been mishandled. Sometimes people use them just to indicate that it might have been dropped, but sometimes they are used to indicate the possibility that the structure has been tilted too far to where things like bus bar supports are compromised from the flexing of the structure itself. Tilting it to get it in the door may do the same thing, or at least indicate to the manufacturer that it may have and thus releasing them from any responsibility.
