5.2 Cooling

Enough free space should be left around the frequency converter 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 required free space 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.

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
