Shipment and Storage
2 Shipment and Storage
2.1 Packaging
To permit the goods to be shipped safely, economically and in accordance with
regulations, they will be made ready for shipment by Siemens prior to actual
packing. Taking into account the various influences on the goods (climate
conditions, total duration
of transport and storage, method of transport), several
different types of packaging are used. The type of packaging is quoted on the
dispatch note and described below.
Packaging:
-Overseas cases made from treated wood orfiberboard suitable for air freight,
sea freight and transportation via road, load bearing capacity 1,000 kg/m2 top
cover area. They are re-usable.
-reinforced cardboard boxes will be used for reduced packaging requirements,
e.g. land transport
2.2 Marking
The packaging has symbols which give instructions for safe transport and proper
storage. For the dispatch
of non-hazardous goods, the following symbols apply.
These symbols must be strictly observed.

as an advisor or supervisor. Transportation remains exclusively the re spo nsibility of
the freight forwarder.
2.3.1 Transport to site
10
& WARNING
Risk of load tipping when loading and un load in g heavy goods
(espe
ci ally if using winch es ,jacks and crowbars, etc.) -danger to life!
• Secure loads during transport.
• Stabilize the transport vehicle with props or jacks during lo ad i ng an d

-Fork-lifts
-Mobile and/or stationary cranes
-Ropes and chains.
All goods must be properly secured during transport to the site.
Special care has to be taking f-or the 3-phase Design 27 switch unit for rated
voltages up to 27 kV. It must only be fixed on the outer fixture seatings of the
housing (see Fi
g. 2) and must not be transported while standing on the parki ng feet
(23).
Note:
It is therefo re advised to use the pa ll et wh ich is part of the
