Cooling components

Depending on the cooling method used, additional fan units and fan compo-
nents, specifically designed for the system, must also be ordered.
A differentiation is made between three different cooling types.
1. For internal cooling, the complete power loss remains in the electrical cabi-
2. With external cooling, the power module power loss (thermal) is externally
3. For pipe cooling, version with 300 mm wide modules with internal cooling,
The mounted fan is connected directly to the control cabinet line supply.

Warning
!
The fan may only be commissioned if it is electrically connected to the module
housing (PE fan via module housing).
Caution
!
If the fan has an incorrect direction of rotation (see arrow) then cooling is not
guaranteed!
