4.1.5.1 General
Fields of application
-
Application of coolers without separately driven fan:
- If e.g. the cooling air is so contaminated that it is not possible to use
separately driven fans. The performance as well as the service life of the
fan would be reduced.
-
High enclosure with thermal separation:
- If thermal separation is required because of the heat generation in the
control cabinet and if the enclosure class of the cooling unit must be
higher than IP41.
-
Application of controllers directly in the machine with reduced assembly
depth:
- Machine components adopt the cooling function.
-
The drive concept provides common cooling units (water cooler, forced-air
cooler, etc.) for all controllers.
-
Because of technical reasons, the convection cooling is not suitable for
continuous powers > 22 kW. Here, forced cooling (e.g. water cooling) is
required.
