Installation Guide
8 | CFW-11
ENGLISH
Do not install heat sensitive components right above the inverter.
NOTE!
The detailed description of all models (IP2X/IP55) of
the CFW-11 frequency inverter is found in the user's
manual, available for download on www.weg.net.
CABINET MOUNTING
Surface assembly:
Provide adequate exhaustion so that the internal cabinet temperature
remains within the allowed range for the inverter operations
conditions.
The power dissipated by the inverter at its rated condition is specified
in table A.1, A.2, A.3 and A.4 “Dissipated power in Watts – Surface
Mounting”.
The cabinet minimum air cooling flow requirements are as shown
in table 1.
The position and diameter of the mounting holes are according to
figure 1.

Flange mounting:
The losses specified in table A.1, A.2, A.3 and A.4, “Dissipated power
in Watts - Flange mounting” will be dissipated inside the cabinet. The
remaining losses will be dissipated through the back side.
