PowerXL FR7 and FR8 Series VFD
Cooling and free space around the AC drive
The AC drive produces heat in operation. The fan circulates air and
decreases the temperature of the drive. Make sure that there is
sufficiently free space around the drive.
Some free space in front of the drive is also necessary for
maintenance. You must be able to open the cabinet door. When you
have 2 or more drives, you can install them side by side.
Make sure that the temperature of the cooling air does not become
higher than the maximum ambient operating temperature or lower
than the minimum ambient operating temperature of the drive.
The air must move freely and efficiently through the cabinet and the
drive. There must be a minimum of 20 cm (7.87 in) of space above
the drive without obstacles that can stop the airflow. Make sure that
the hot air goes out of the cabinet and does not come back into the
cabinet.
