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 around the inverter: 0 ºC (32 ºF) up to the rated temperature indicated in
„
B4 on page 135:
- 200 V Line: from 0 ºC to 50 ºC (32 ºF to 122 ºF).
- 400 V Line: from 0 ºC to 40 ºC (32 ºF to 104 ºF).
For temperatures surrounding the inverter higher than the specifications above, it is necessary
„
to apply a 2 % of current derating for each degree Celsius (1.1 % for each degree Fahrenheit),
limited to an increase of 10 ºC (18 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
„
(330 ft) above 1000 m (3.300 ft) of altitude.
From 2000 m to 4000 m (6.600 ft to 13.200 ft) above sea level – maximum voltage derating
„
(127 V / 240 V / 480 V, according to the model, as indicated in
1.1 % for each 100 m (330 ft) above 2000 m (6.600 ft).
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, likewise the inverter net weight (mass) are shown in
Figure B1 on page 141.
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.
