Reusing the transport unit
Reusing the transport unit To transport the vacuum circuit-breaker again, the pallet with carton or the wooden

Do not reuse severed tensioning straps or plastic wrap.
Pack the vacuum circuit-breaker in reverse order:
• Attach the vacuum circuit-breaker safely to the pallet using the appropriate
tools.
• Cover with foil and seal with adhesive tape.
• Attach accessories pack.
• Attach carton securely to the pallet base.
• Screw the wooden case back together.

Note
Risk of corrosion damage if stored improperly!
If the storage conditions listed below are met, the vacuum circuit-breaker can be
stored for up to a year in its transport unit.
If the storage conditions are not met, the vacuum circuit-breaker cannot be stored
in the transport unit any longer than 6 months.
If storage of longer than one year is planned, unpack the vacuum circuit-breaker
from the transport unit. Further storage may necessitate fresh corrosion
