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 liquids or gases.
„
Excessive vibration.
„
Dust, metallic particles or oil mist.
„
Environmental conditions permitted for the operation of the inverter:
Temperature surrounding the inverter: from -10 ºC (14 ºF) to the nominal temperature specified
„
in Table B.2 on page
For temperatures surrounding the inverter higher than the specifications above, it is necessary
„
to apply a 2 % of current derating for each Celsius degree, 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) - nominal conditions.
„
1000 m to 4000 m (3.300 ft to 13.200 ft) - 1 % of current derating for each 100 m (328 ft)
„
above 1000 m of altitude.
From 2000 m to 4000 m (6.600 ft to 13.200 ft) above sea level - maximum voltage reduction
„
(240 V for 200...240 V models, 480 V for 380...480 V models and 600 V for 500...600 V models)
of 1.1 % for each 100 m (330 ft) above 2000 m (6.600 ft).
Pollution degree: 2 (according to EN 50178 and UL 508C), with non-conductive pollution.
„
Condensation must not originate conduction through the accumulated residues.

3.1.2 Positioning and Mounting

The external dimensions and the drilling for the mounting, as well as the net weight (mass) of
the inverter are presented in
to Figure B.4 on page
B.7 on page
Mount the inverter in the upright position on a flat and vertical surface. First, put the screws on
the surface where the inverter will be installed, install the inverter and then tighten the screws
observing the maximum torque for the screws indicated in
Allow the minimum clearances indicated in
air circulation. Do not install heat sensitive components right above the inverter.
