The following tables list the maximum permissible thermal resistance R
th
of the external heat sink and
the device-specific energy dissipation P
d
of the external heat sink. The thermal resistance R
th
is given
in the unit Kelvin per Watt (K/W). The value of R
th
can typically be taken from the data sheet of the
external heat sink. Additionally, the thermal radiation (energy dissipation, interior) of the frequency
inverter is indicated in the table.

The thermal resistance values and the technical data apply in the following conditions:
− No airflow.
− Clearance of approx. 300 mm above and below as well as 100 mm on both the left and right side
of the frequency inverter.
The energy dissipation values are also valid for the switching frequencies of 4, 8, 12 and 16 kHz, as at
these operating points, the output current is reduced.
