Completeness and correctness. (Check against order and delivery documents)
Any possible damage in transit and material losses.
Abnormality, if any, must be notified immediately to: ABB, Nasik , forwarding agents
and the insurance company.
2.2 Operating Mechanism
The operating mechanism should be unpacked on arrival. If it is not going to be stored in an
approved storage (Note 1), the heating elements must be connected permanently to the
electric supply to protect the control equipment from corrosion or freezing damage.
2.3 Circuit-Breakers
The breaker should be stored in their original transport units, where they are well protected
from damage. The unit shall be prevented from standing in water. The breakers which are
stored outdoors, should be covered with at least a tarpaulin. The tarpaulin should not be
placed directly onto the galvanized surface. An air gap should be left to prevent
condensation.
The minimum allowed ambient tem perature for the Outdoor Vacuum Circuit Breaker is
-30°C.
2.4 Spare parts
The spare parts shall be stored indoors in an approved storage (Note 1), in their original
units. This is particularly valid for rubber sealing parts, which must also be protected from
sunlight in order to prevent them from ageing. Rubber sealing can be stored only for a
limited period, so avoid storage of these parts. Structures may be stored outdoors.
Note 1:
We define an approved storage with:
Roof
Solid ground
Relative humidity less than 50%
Temperature 20°C (± 10° C)
