Horizontal installation

SINAMICS S120 Liquid Cooled units can operate in a vertical position with the unit resting
on its rear panel.
To prevent heat concentrations inside the units in this mounting position, an external fan
needs to be installed which is capable of removing heated air from the devices.
A baffle (referred to below as air distribution baffle) must also be mounted above the unit.
This ensures that the air is sucked through the IP20 covers in an even distribution over the
entire length of the device, thereby ensuring that even components at the bottom left of the
module remain within the permissible tolerance range (see Figure below).
The components required for a horizontal mounting position can be seen in the Figure
below.
Figure 7-1
The height h (the distance between the module top edge (horizontal) and the air distribution
baffle A) must be in the range 25 mm < h < 60 mm!
