3.4 Cooling
The AC drive produces heat in operation and is cooled down by air circulated by a fan. The cooling
concept is independent of the motor fan.
Enough free space shall be left around the AC drive to ensure sufficient air circulation and cooling.
Different acts of maintenance may also require a certain amount of free space.
The minimum clearances given in Table 9 must not be exceeded. It is also important to ensure that
the temperature of the cooling air does not exceed the maximum ambient temperature of the con-
verter.
Contact local VACON

distributor for more information on required clearances in different instal-
lations.
