Back cooling
Using the channel from the back allows for easy installation in control rooms, for example. The
unit mounted at the rear of the enclosure allows for the cooling of the units just as easily as the
duct cooling principle. The hot air is ventilated out of the back of the enclosure. This offers a
solution in which the hot cooling air from the adjustable frequency drive does not cause the control
room to heat up.
NOTE
A small door fan is required on the Rittal cabinet to provide additional cooling within
the drive.
