When variable frequency drives with internal fans are installed vertically over
each other, an air baffle must be placed between the devices. Failure to do
so may expose the device on top to a thermal overload caused by the guided
air flow (device fan).

Table 3:
Recommended values for minimum clearances and required cooling air (see fig. 21,
22)
The values specified in
Table 3 are recommended values for an ambient
temperature of up to +50 °C with an IP20 degree of protection or +40 °C
with an IP66 degree of protection, an installation altitude of up to 1000 m,
and a switching frequency of up to 8 kHz.
￫
Devices with high magnetic fields (e. g. reactors or
transformers) should not be installed close to the variable
frequency drive.
