Installations 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:
• Less efcient cooling and therefore a greater likelihood of the device
going into derating because of high internal temperatures.
• Reduction in the dielectric resistance of the air which, in the presence
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 because of cosmic radiation.
All installations at altitudes exceeding 2000 metres are not recommended on the basis of the
criticalities indicated above.
Installations 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 conden-
sation inside the inverter.
As the inverter is almost completely insulated from the outside, conden-
sation can also form after installation in certain weather conditions.
