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).

Deflector due to increased circulation caused by device fan
￫
Devices with high magnetic fields (e. g. reactors or
transformers) should not be installed close to the variable
frequency drive.
