The sample below clearly shows the maximum permitted ambient air temperature
at a specific power loss for different cabinet designs.

The following device configuration should be installed in a cabinet:
• Central unit, 150 W
• Expansion modules, each with 150 W
• Load power supply under full load, 200 W
This results in a total power loss of 650 W.

The diagram in the figure below shows guide values for the permitted ambient air
temperature of a cabinet with the dimensions 600 mm x 600 mm x 2,000 mm,
depending on power loss. these values only apply if you maintain the specified
installation and clearance dimensions for racks (rails).
