Mechanical Installation - Danfoss VT2800 Series Design Manual

Mechanical installation

Please pay attention to the requirements
that apply to installation.
The frequency converter is
cooled by means of air circulation. 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. temperature
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 converter
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.
