2 Assembly and installation
SK 500E frequency inverters are available in various sizes depending on the output. Attention must be
paid to a suitable position when installing.
The equipment requires sufficient ventilation to protect against overheating. For this the minimum
guideline 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. However, for the use of
brake resistances mounted below the frequency inverter (not possible with …-CP devices), the greater
width must be taken into consideration, particularly in combination with temperature switches on the
brake resistor!
Installation position: The installation position is normally vertical. It must be ensured that the cooling
ribs on the rear of the frequency inverter are covered with a flat surface to provide good convection.
Warm air must be vented above the device!

If several inverters are arranged above each other, it must be ensured that the upper air entry
temperature limit is not exceeded (chapter 7). 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
impeded.
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.
