For sufficient ventilation of the components you have to comply with the
minimum distances below. At components without integrated braking
resistor, there will be temperatures of up to 105 °C at the air outlet (B)
(with an air intake temperature of 45 °C).

additionally take power
at braking resistor into
account
1) for additional mounting parts, such as HAS, see dimensional
drawings
2) integrated braking resistors require additional distance
Fig. 6-6: Minimum distance for ventilation
Note: If there are different minimum distances for the individual
components in a drive system, the greatest value determines
the minimum distance to be observed.
For components with integrated braking resistor (supply units, DC bus
resistor units, HCS02 drive controllers) their higher outlet temperatures
have to be taken into account.
To determine the required distances the resulting outlet temperatures are
indicated in diagrams in the technical data of the components.
Input value in the diagrams is the generated power of the braking
resistors or the individual output current. See exemplary diagram below:
