B – INSTALLATION SITE CHARACTERISTICS
Following the recommendations below will ensure the capacitor bank works correctly:
Min./max. temperature: -5°C to +40°C
Average temperature over 24 hrs: +35°C
Max. altitude ≤ 2000 m
Environment:
o Maximum humidity rate ≤ 80%
o Free of dust
o No corrosive products present
Ventilation:
o 200 mm minimum space must be left around the ventilation louvres
(wall, ceiling, other elements)
o The air intakes and outlets must not be blocked
o Ventilation of the capacitor bank is provided by the flow of air:
Air intake via the bottom, as the ventilation louvres are located on the
front and back as well as on the sides.
Outlet via the top:
Banks without detuned reactors natural extraction
through the louvres on the front and back as well as on
the sides.
Banks with detuned reactors forced extraction
(1)
through the fans located on the enclosure roof.
(1)
Natural extraction for SAH type enclosures with power ≤ 150 kVAr.
Any failure to follow procedures and warnings to the letter can lead to premature
failure, explosion, or an outbreak of fire in the equipment, and will automatically
invalidate the enclosure warranty.
