3 INSTALLATION AND CONNECTION

3.1 MECHANICAL INSTALLATION

3.1.1 Environmental Conditions

Avoid:
Direct exposure to sunlight, rain, high humidity or sea-air.
„
Inflammable or corrosive gases or liquids.
„
Excessive vibration.
„
Dust, metallic particles or oil mist.
„
Environment conditions permitted for the operation of the inverter:
Temperature surrounding the inverter: 0 ºC to 50 ºC – IP20.
„
For temperatures surrounding the inverter higher than the specifications above, it is necessary
„
to apply a 2 % of current derating for each degree Celsius, limited to an increase of 10 ºC.
Air relative humidity: 5 % to 90 % non-condensing.
„
Maximum altitude: up to 1000 m (3.300 ft) - rated conditions.
„
From 1000 m to 4000 m (3.300 ft to 13.200 ft) – 1 % of current derating for each 100 m above
„
1000 m of altitude.
Pollution degree: 2 (according to EN50178 and UL508C), with non-conductive pollution.
„
Condensation must not originate conduction through the accumulated residues.
