Allowed Mounting Position
a
Mounting surface
G1
Normal mounting positions. The natural
convection supports the forced cooling
air current. This avoids the generation of
pockets of heat in the component.

Turned by 90° from vertical to horizontal
mounting position

Sizing of Enclosure and Control Cabinet
Multiple-Line Design of the Control Cabinet
Arrangement of the devices, air guides/drip protections, fans
Pay particular attention to the maximum allowed air intake temperature of devices
when they are arranged in multiple lines in the control cabinet.
If possible, place devices with a high degree of power dissipation (e.g. supply units with
braking resistors, DC bus resistor units)
● in the top line and
● near the outlet air aperture to the cooling unit
Mount air guides between the lines to
● protect the devices in the upper lines against the warm outlet air of the devices be‐
neath and
● protect the devices beneath against penetration of liquids (e.g. dripping condensa‐
tion water or leaking cooling liquid)
