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.
„
From 2000 m to 4000 m above sea level - maximum voltage reduction (127 V / 240 V, according to the model,
„
as specified in Table B.1 on page
Pollution degree: 2 (according to EN50178 and UL508C/UL61800-5-1), 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
Mount the inverter in the upright position on a flat and vertical surface. Allow the minimum clearances indicated in
Figure B.2 on page 96, in order to allow the circulation of the cooling air. Do not install heat sensitive components
right above the inverter.
ATTENTION!
When installing two or more inverters vertically, respect the minimum clearance A + B (as shown
„
in Figure B.2 on page
lower inverter does not affect the top inverter.
Provide independent conduits for the physical separation of signal, control and power cables (refer
„
to Section 3.2 ELECTRICAL INSTALLATION on page

3.1.2.1 Cabinet Mounting

For inverters installed inside cabinets or metallic boxes, provide proper exhaustion, so that the temperature remains
within the allowed range. Refer to the dissipated powers in
As a reference, Table 3.1 on page 13
