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.
the following conditions recommended:
• Ambient air temperature should not exceed 40 ºC
and its mean value, measured in a period of 24 hours,
should not exceed 35 ºC.
• The ambient air temperature should not drop
below - 5 ºC. There are also cubicles with storage
temperature up to - 40 ºC.
• The switchgear must be protected from direct solar
radiation.
• Maximum altitude is 2000 m.
• The environmental air must not have any significant
contamination from dust, smoke, corrosive and/or
inflammable gases, vapours or salt.
• The switchgear must be protected from the rain,
and the humidity conditions should be as follows:
o the mean relative humidity value, measured over a
period of 24 hours, must not exceed 95%.
o The mean water steam pressure value, measured in
a period of 24 hours, must not exceed 2.2 kPa.
o the mean relative humidity value, measured over a
period of one month, must not exceed 90%.
o The mean water steam pressure value, measured in
a period of 1.8 hours, must not exceed 1.8 kPa.
• 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 manometer needle may indicate an incorrect value, even if the equipment’s
internal gas pressure is correct.
