INSTALLATION
This chapter describes the procedures for the electrical and mechanical
installation of the CFW-08.
These guidelines and suggestions must be followed for proper CFW-08
operation.
3.1.1 Environment
The location of the inverter installation is an important factor to assure
good performance and high product reliability. For proper installation, we
make the following recommendations:
Avoid direct exposure to sunlight, rain, high moisture and sea air.
Avoid exposure to gases or explosive or corrosive liquids;
Avoid exposure to excessive vibration, dust, oil or any conductive
particles or materials.
Environmental Conditions:
Temperature : 32...104ºF (0 ... 40ºC) - nominal conditions. 32...122ºF
(0 ... 50ºC) - with 2% current derating for each 1.8ºF (1ºC) degree
above 104ºF (40ºC).
Relative Air Humidity: 5% to 90% - non-condensing.
Maximum Altitude: 3,300 ft (1000m) - nominal conditions.
3,300...13,200 ft (1000 ... 4000m) - with 10% current reduction for
each 3,300 ft (1000m) above 3,300 ft (1000m).
Pollution Degree: 2 (according to EN50178 and UL508C)
NOTE!
When inverters are installed in panels or in closed metallic boxes, adequate
cooling is required to ensure that the temperature arounds the inverter will
not exceed the maximim allowed temperature. See Dissipated Power in
Section 9.1.
