Support the plinth of the cabinet all round.
The air duct must be able to supply a sufficient volume of cooling air. See technical data for
the minimum air flow values.
WARNING!
Make sure that the incoming air is sufficiently clean. If not, dust goes into the
cabinet. The outlet filter on the cabinet roof prevents dust from going out. The
collected dust can cause drive malfunction and danger of fire.

The option adds air outlet ducts to each cubicle of the cabinet line-up. The outlet diameter
(and quantity) of the ducts depend on the cubicle width. The ducts used are from the Veloduct
series by FläktGroup.

The ventilation system must keep the static pressure in the air outlet duct sufficiently below
the pressure of the room where the drive is located in order that the cabinet fans can produce
the required air flow through the cabinet. Make sure that no dirty or moist air is able to flow
backward to the drive in any case, even during off-time or while servicing the drive or the
ventilation system.
