in accordance with IEC Standard
Storage
5. Storage
If it needs to be stored, the material must be placed on dry
ground or damp-proof insulating material, still in its original
packing, in order to prevent any damage during storage.
After prolonged storage, clean all the insulating parts
carefully before commissioning the equipment. The
enclosure should be cleaned with a clean, dry lint-free cloth.
Figure 5.1. Storage conditions detail
Storage must always be INDOORS, with the following
conditions recommended:
1.
Ambient air temperature should not exceed 40 ºC
and its mean value, measured in a period of 24 hours,
should not exceed 35 ºC.
2. The ambient air temperature should not drop below
- 5°C. There are also cubicles with storage temperature
up to -15°C and up to -25ºC.
3. The switchgear must be protected from direct solar
radiation.
4.
Maximum altitude is 1000 m.
5.
The environmental air must not have any significant
contamination from dust, smoke, corrosive and/or
inflammable gases, vapours or salt.
6. The switchgear must be protected from the rain, and
the humidity conditions must be as follows:
a. The average relative humidity value, measured over
a period of 24 hours, must not exceed 95 %.
b. The average water vapour pressure value, measured
over a period of 24 hours, must not exceed 22 mbar.
c. The average relative humidity value, measured over
a period of one month, must not exceed 90 %.
d.
The average water vapour pressure value, measured
over a period of one month, must not exceed
18 mbar.
7.
During transport, vibrations caused by external factors
or seismic movements must be insignificant.
Any other conditions must be notified beforehand, since
the equipment must be factory-adjusted to atmospheric
pressure at the destination. If this is not the case, the
manometer needle may indicate an incorrect value, even if
the equipment's internal pressure is correct.
