3 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.
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.

Detail of storage conditions
Storage should always be INDOORS, with the following
recommended conditions:
1.
Ambient air temperature must not exceed 40°C and
its average value measured over a 24 h period must
not exceed 35°C.
2.
Ambient air temperature must not drop below - 5 °C.
Cubicles with storage temperature up to - 40 ºC are
also available.
3.
The switchgear must be protected from direct sunlight.
4.
The altitude will be no higher than 1000 m.
5.
The ambient air must not be significantly polluted
by dust, smoke, corrosive and/or flammable gases
vapours or salt.
6.
The switchgear must be protected from rain and the
humidity conditions are as follows:
-
Average relative humidity value, measured in a
24 hour period, must not exceed 95%.
-
Average steam pressure value, measured in a
24 hour period, must not exceed 2.2 kPa.
-
Average relative humidity value, measured in a
1-month period, must not exceed 90%.
-
Average steam pressure value, measured in a
1-month period, must not exceed 1.8 kPa.
7.
During transport, vibrations due to external causes or
seismic movements will be insignificant.
Any other conditions must be notified
beforehand, since the equipment must
be factory-adjusted to the atmospheric
pressure at the destination or during
transport. Otherwise, the manometer needle
may indicate an incorrect value, even if the
equipment's internal gas pressure is correct.
