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
) and the
air outlet temperature (t
OUT
) [ºC or K]
3. Calculate the necessary air quantity in m
3
/h:
Insert t
OUT
- t
IN
in Kelvin
•
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
IN
) 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
OUT
) may not exceed 60ºC
