Cooling components

Depending on the cooling type, matching supplementary fan units and fan
components must be selected.
A differentiation is made between three different cooling types.
1. For internal cooling, the complete heat loss remains in the electrical cabinet
2. For external cooling, the power module power losses are dissipated
3. For hose cooling, the complete power loss is dissipated externally through a
Fig. 2-4 System configuration with 400 V fan (only for 300 mm modules)
Warning
!
The fan may only be commissioned, if it is electrically connected with the
module housing (the PE of the fan is connected via the module housing).
Caution
!
Cooling is not guaranteed if the fan rotates with the wrong direction of rotation
(refer to the arrow)!
