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:
• Less efficient 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 pres-
ence of high operating voltages (DC input), can create elec-
tric arcs (electrical discharges) that may damage the device.
As the altitude increases, the failure rate of some electronic compo-
nents increases exponentially because of cosmic radiation.
All installations at altitudes exceeding 2000 metres are not recommended on the basis of the
criticalities indicated above.

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 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.
