2.4 Temporary storage
2.4.1 General warnings and cautions
CAUTION
The packing must be kept indoors immediately
after arrival. The conditions must meet the
environmental requirements of the IEC 60721-3-1
Standard, classification 1K3
CAUTION
The vapour corrosion inhibitors placed in the units
for protection against humidity during temporary
storage and transport must not be removed until
installation is completed
CAUTION
The duration of the protective effect of the packing
is limited to a few months when stored indoors in a
dry place. ABB should be consulted in the case of
longer storage periods or if the storage conditions
differ from those indicated
2.4.2 Optimum storage conditions
Definition: Optimum temporary storage, without
negative consequences, depends on compliance
with the minimum requirements for the units and
packing materials.
