3.1.2 Cooling
Enough free space shall be left above and below the frequency converter to ensure
sufficient air circulation and cooling. You will find the required dimensions for free
space in the table below.
If several units are mounted above each other the required free space equals C + D
(see Installation space). Moreover, the outlet air used for cooling by the lower unit
must be directed away from the air intake of the upper unit.
The amount of cooling air required is indicated below. Also make sure that the tem-
perature of the cooling air does not exceed the maximum ambient temperature of
the converter.
*. Min clearance A and B for drives for
MI1 ~ MI3 can be 0 mm if the ambient
temperature is below 40 degrees.
Figure 3.5: Installation space
A = clearance around the freq. converter (see also B)
B = distance from one frequency converter to another or distance to
cabinet wall
C = free space above the frequency converter
D = free space underneath the frequency converter
NOTE!
See the mounting dimensions on the back of the drive.
Leave free space for cooling above (100 mm) , below (50 mm) , and on the sides
(20 mm)
of Vacon 10! For MI1 - MI3, side-to-side installation allowed only if the am-
bient temperature is below 40 °C
