WARNING
5 5
Pay attention to the requirements that apply to
integration and the field mounting kit. Observe the
information in the list to avoid serious injury or
equipment damage, especially when installing large
units.
CAUTION
The adjustable frequency drive is cooled by air
circulation.
To protect the unit from overheating, it must be ensured
that the ambient temperature does not exceed the
maximum temperature stated for the adjustable frequency
drive, and that the 24-hour average temperature is not
exceeded. Locate the maximum temperature and 24-hour
average in chapter 9.6.2 Derating for Ambient
Temperature.
If the ambient temperature is in the range of 113–131 °F
[45 °C–55 °C], derating of the adjustable frequency drive
becomes relevant, see chapter 9.6.2 Derating for Ambient
Temperature.
The service life of the adjustable frequency drive is
reduced if derating for ambient temperature is not taken
into account.
