INSTALLATION AND CONNECTION

This chapter describes the procedures for the electrical and
mechanical installation of the CFW-10.
These guidelines and suggestions must be followed for proper
operation of the CFW-10.
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 : 0ºC to 50ºC (32ºF to 122ºF) - nominal
conditions.
Relative Air Humidity: 5% to 90% - non-condensing.
Maximum Altitude: 1000m (3,300 ft) - nominal conditions.
From 1000m to 4000m (3,3 ft to 13,200 ft): with 1% current
derating for each 100m (330 ft) above 1000m (3,300 ft).
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.
