5 Storage conditions
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.
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.

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 ºC.
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 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
at the final destination or during transport.
Otherwise, the pressure switch may indicate an
incorrect value, even if the equipment's internal
gas pressure is correct.
