In order not to damage open mounting parts (e.g. pipes and busbars), take the following
measures when removing the foil and the load securing devices:
● Remove the foil and load securing devices carefully.
● Remove the packaging immediately prior to installation. Protect the cabinets against dust
until they have been commissioned. To do this, cover the ventilation openings and keep the
doors closed.
● Do not remove the safety instructions and center of gravity specifications from the cabinet.
