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 ( 32 ºF to 122 ºF) – 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 (50 ºF).
Air relative humidity: 5 % to 95 % 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.

3.1.2 Positioning and Mounting

The external dimensions and fixing holes, and the inverter net weight (mass) are shown in
B1 on page 123.
Mount the inverter in the upright position on a flat and vertical surface. Allow the minimum
clearances indicated in
air. Do not install heat sensitive components right above the inverter.
