Installation
■ Installation of VLT 5072-5202 400-500 V
Compact IP20/IP00
Cooling
All Compact units in the above-mentioned series
require a minimum space of 225 mm above and
below the enclosure and must be installed on a
plane, vertical surface (no spacers).
Side-by-side
Compact IP 00/IP20
All units in the above-mentioned series can be installed
side by side without any space between them.
■ Ventilation when Panelmounted
The quantity of air needed to cool VLT 5000 Crane
can be calculated as follows:
1. Add up the values of P
for all VLT 5000 Crane
to be installed at the same panel (
P )[W]
2. Determine the air inlet temperature (t
IN
)andthe
air outlet temperature (t
OUT
)[ºCorK]
3. Calculate the necessary air quantity in m

• The output from the fan must be located above
the highest mounted frequency converter
• Remember to take pressure drops over filters
into account and that the pressure decreases
as the filters are choked
• The max. cooling air temperature (t

)must
be lower than 55ºC. The average of day/night
temperature may be 5ºC lower than that stated
in VDE 160. The cooling outlet temperature
(t
