5.2 Cooling
Enough free space should be left around the frequency drive to ensure sufficient air circulation
and cooling. The required dimensions for free space are in the table below.
If several units are mounted above each other the the required free space between the stacked
units equals C + D (see figure below). Moreover, the outlet air used for cooling by the lower unit
must be directed away from the inlet air to be used by the upper unit.

Table 5-9. Mounting space dimensions
A = clearance around the freq. converter (see also A 2 and B)
A 2 = clearance needed on either side of the frequency converter
for fan change (without disconneting the motor cables)
* = min. clearance for fan change (without disconnecting the
motor cables) between two frequency converters
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
