3.2 WATER-COOLED UP11W G2 MECHANICAL INSTALLATION

The power units must be installed in the drive panel appropriately, allowing easy extraction and reinstallation in
case of maintenance. The mounting must be such to avoid damage during the panel transportation.

3.2.1 Environmental Conditions

Avoid:
Direct exposure to sunlight, rain and high humidity.
„
Inflammable or corrosive liquids or gases.
„
Dust, metal particles or oil suspended in the air.
„
Environment conditions permitted for operation:
Ambient temperature: 0 °C to 45 °C (32 ºF to 113 ºF) - rated conditions (measured around the inverter). From
„
45 ºC to 55 ºC (113 ºF to 131 ºF) - 0.5 % of current derating for each Celsius degree above 45 ºC (113 ºF).
Coolant input temperature: 0 ºC to 45 ºC (32 ºF to 113 ºF) according to the coolant used. From 45 ºC to 55 ºC
„
(113 ºF to 131 ºF) - 1 % of current derating for each Celsius degree above 45 ºC (113 ºF).
Coolant flow: 20 l/min.
„
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.
