Positioning And Mounting - WEG CFW-11 User Manual

Installation and Connection
From 2000 m to 4000 m (6.600 ft to 13.200 ft) above sea level - derating of maximum voltage of 1.1 %
for each 100 m (330 ft) above 2000 m (6.600 ft).
Humidity: from 5 % to 95 % non-condensing.
Pollution degree: 2 (according to EN50178 and UL508C) with non-conductive pollution. Condensation
shall not originate conduction through the accumulated residues.

3.1.2 Positioning and Mounting

Consult the inverter weight at the
8-5.
Mount the inverter in the upright position on a flat and vertical surface.
External dimensions and fixing holes position according to the

First mark the mounting points and drill the mouting holes. Then, position the inverter and firmly tighten the
screws in all four corners to secure the inverter.
Minimum mounting clearances requirements for proper cooling air circulation are specified in
page 3-4.
Do not install heat sensitive components right above the inverter.
ATTENTION!
When arranging two or more inverters vertically, respect the minimum clearance A + B
