Installations Above 2000 Metres; Installations With A High Level Of Humidity - ABB REACT 2 Series Product Manual

I
nstallations above 2000 metres
On account of the rarefaction of the air (at high altitudes), particular
conditions may occur that should be considered when choosing the
place of installation:
going into derating because of high internal temperatures.
of high operating voltages (DC input), can create electric arcs (electrical
discharges) that may damage the device.
As the altitude increases, the failure rate of some electronic components
increases exponentially.
The inverter operates normally up to 2000 meters.
Above 2000 meters the inverter works in derating (second curve derating by altitude).

nstallations with a high level of humidity
Never open the inverter in the case of rain, snow or a level of humidity >95%.
Always carefully seal all unused openings.
Even though the device is equipped with an anti-condensation valve,
air with extremely high levels of humidity can lead to the creation of
condensation inside the inverter.
As the inverter is almost completely insulated from the outside,
condensation can also form after installation in certain weather conditions.
cooling and therefore a greater likelihood of the device
