Figure 7-3-1 6kV Air Cooling Tube
In case of high ambient temperature or poor ventilation, it is necessary to install the circulation fan or the
corresponding industrial air conditioning. In order to reduce the ambient temperature of VFD, a concentrated
ventilation tube could be installed by the customer. The hot air can be ejected outdoors by the centrifugal blower
through the ventilation tube. The concentrated ventilation tube is directly connected to cooling blowers on the top
of the cabinet, as shown in Figure 7-4.
