Mechanical Installation - Danfoss VLT 2800 Series Operating Instructions Manual

Mechanical installation

Please pay attention to the requirements
that apply to installation.
The frequency converter is cooled by means of air cir-
culation. For the unit to be able to release its cooling
air, the minimum free distance above and below the
unit must be minimum 100 mm . To protect the unit
from overheating, it must be ensured that the ambient
temperature does not rise above the max. temperature
stated for the frequency converter and that the 24-hour
average temperature is not exceeded. The max. tem-
perature and 24-hour average can be seen in General
technical data. If the ambient temperature is in the
range of 45 °C - 55 °C, derating of the frequency con-
verter is to be carried out. See Derating for ambient
temperature. Please note that the service life of the
frequency converter will be reduced if no allowance is
made for the derating for ambient temperature.
Integration
All units with enclosure IP 20 must be integrated in
cabinets and panels. IP 20 is not suitable for remote
mounting. In some countries, e.g. in the USA, units
with enclosure NEMA 1 are approved for remote
mounting.
Spacing for mechanical installation
All units require a minimum of 100 mm air between
other components and vents of the enclosure.

VLT 2800 Series
Side-by-side
All VLT 2800 units can be installed side-by-side and in
any position, as the units do not require ventilation on
the side.
NB!
With the IP 21 solution all units require a
minimum of 100 mm air on each side. This
means that side-by-side mounting is not
allowed.
