Environmental checks
• Consult the technical data to check the required environmental condi-
tions (protection rating, temperature, humidity, altitude, etc.)
• Installation of the unit in a location exposed to direct sunlight must be
avoided (otherwise the warranty will be cancelled) as it may cause:
- power limitation phenomena in the inverter (with a resulting decreased
energy production by the system)
- premature wear of the electrical/electromechanical components
- premature wear of the mechanical components (gaskets) and of the
user interface (display)
• Do not install in small closed rooms where air cannot circulate freely
• Always ensure that the ow of air around the inverter is not blocked so
as to prevent overheating.
• Do not install near ammable substances (minimum distance 3 m)
• Do not install near walls made of wood or other ammable substances.
• Do not install in rooms where people live or where the prolonged pres-
ence of people or animals is expected, because of the high noise that
the inverter produces during operation. The level of the sound emission
is heavily inuenced by where the inverter is installed (for example: the
type of surface around the inverter, the general properties of the room,
etc.) and the quality of the electricity supply.
• Avoid electromagnetic interference that can compromise the correct op-
eration of electronic equipment, with the consequent hazards
Final installation of the equipment must not compromise access to any disconnection devices
that may be located externally.
Please refer to the warranty terms and conditions to evaluate any possible warranty exclu-
sions due to improper installation.
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 equipment.
As the altitude increases, the failure rate of some electronic components
increases exponentially because of cosmic radiation.
All installations at altitudes of over 2000 metres must be assessed case by case considering
the aforesaid criticalities.
