2 Assembly and installation
The frequency inverters are available in various sizes depending on their output. Attention must be
paid to a suitable position when installing.
The equipment requires sufficient ventilation for protection against overheating .For this the minimum
distances from adjacent components above and below the frequency inverter, which could obstruct
the air flow apply.
(above > 100 mm, below > 100 mm)
Distance from device: Mounting can be immediately next to each other.
Installation position: Always install the frequency inverter vertically on a plane surface.
Warm air must be vented above the device!
Figure 1: Installation spacings
If several inverters are arranged above each other, it must be ensured that the upper air entry
temperature limit is not exceeded ( Section 7 "Technical data"). If this is the case, it is
recommended that an "obstacle" (e.g. a cable duct) is mounted between the inverters so that the
direct air flow (rising warm air) is interrupted.
Heat dissipation: If the frequency inverter is installed in a control cabinet, adequate ventilation must
be ensured. The heat dissipation in operation is approx. 5 % (according to the size and equipment of
the device) of the rated power of the frequency inverter.
