Preparation for use
7.1 Transporting
To achieve mutual optimal weakening of the magnetic fields (magnetic interference fields)
the original and individual packaging of two secondary sections must always be stacked on
one another in pairs, alternating according to the following diagram. In each case, edge A-B
of the lower individual package must be placed on the edge C-D of the upper individual
package.
Figure 7-1 Packing for secondary sections and correct stacking
The precondition for correctly stacking two secondary sections is an offset within a
secondary section pair of less than 1 cm, which must be guaranteed for the complete
duration of the air transport. To achieve this, fix the original individual packaging, e.g. using
adhesive packaging tape. When required, use transparent adhesive packaging tape in order
not to cover any safety instructions.
If the individual packages with the secondary sections are not stacked pairwise alternating
on top of one another, the magnetic fields strengthen one another. If the offset within a
secondary section pair is larger than 1 cm during the complete duration of the air transport,
then the magnetic fields also strengthen one another.
In bulk packaging, secondary section pairs (each pair stacked alternating, according to the
diagram "Packaging for secondary sections and correct stacking") can be arranged as
required.
