5. Storage
If it needs to be stored, the equipment must be placed on
dry ground or on top of damp-proof insulating material, still
in its original packaging, ensuring it is not damaged during
the storage period.
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 5.7.
Storage conditions detail
Storage must always be INDOORS, with the following
conditions recommended:
1.
Ambient air temperature should not exceed 104 °F
(40 °C) and its mean value, measured in a period of
24 hours, should not exceed 95 °F (35 °C).
2.
The ambient air temperature should not drop below
23 °F (- 5 °C).
3.
The switchgear must be protected from direct solar
radiation.
4.
Maximum altitude is 3250 ft / 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 should be as follows:
a.
The mean relative humidity value, measured over a
period of 24 hours, must not exceed 95 %.
b.
The mean water steam pressure value, measured in
a period of 24 hours, must not exceed 2.2 kPa.
c.
The mean relative humidity value, measured over a
period of one month, must not exceed 90 %.
d.
The mean water steam pressure value, measured in
a period of one month, must not exceed 1.8 kPa.
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 the
atmospheric pressure. Otherwise, the needle may
indicate an incorrect value (red scale), even though
the value of the equipment internal pressure is correct.
Otherwise, the manometer needle may indicate
an incorrect value, even if the equipment’s internal
pressure is correct.
