Back cooling
Using the channel from the back allows easy installation in for example control rooms. The unit
mounted to the rear of the enclosure allows a similar easy cooling of the units as the duct cooling
principle. The hot air is ventilated out of the back of the enclosure. This offers a solution where
the hot cooling air from the frequency converter does not cause heating of the control room.
