■ Mechanical installation
Please pay attention to th e 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 a ir, the minimum free
distance above and below the unit must be m
inimum
100 mm . T o protect the unit from overheat ing, it
must be ensured that the ambient temperature does
not rise above the m ax. 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 Derat ing for ambient
temperature. Pleasenotethattheservicelifeofthe
frequency converter will be reduced if no allowance is
made for the derating for ambie nt temperature.
■ Integration
All units with enclosure IP 20 must b e integrated
in cabinets and panels. IP 20 is not suitable
for remote mounting. In some countries, e.g.
in the U SA, units with enclosure NEMA 1 are
approved for remote mount ing.
■ Spacing for mechanical installation
All units require a minimum of 100 mm air between
other c omponents and vents of the enclosure.
■ 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 m inimum of 100 mm air on each
side. This means that side-by-side
mounting is n
ot allowed.
