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.4 on page 162 and Table B.5 on page 164.
Inverters for mechanics A to E: for temperatures surrounding the inverter higher than the
specifications in Table B.4 on page 162, it is necessary to apply of 2 % of current derating
for each Celsius degree, limited to an increase of 10 ºC (50 ºF).
Inverters for mechanics F: for temperatures surrounding the inverter higher than the
specifications in Table B.5 on page 164, it is necessary to apply of 1 % of current derating
for each Celsius degree, until 50 ºC (122 °F) and 2 % of current derating for each Celsius
degree, until 60 ºC (140 °F).
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 Figure B.2 on page 170. For further details of each frame size,
refer to Figure B.5 on page 175, Figure B.6 on page 176, Figure B.7 on page 177, Figure
B.8 on page 178, Figure B.9 on page 179 and Figure B.10 on page 180.
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 Figure B.2 on page 170.
