Design Guide | iC7 Series Air-cooled System Modules
In the system modules with integration units, there are 2 methods to arrange inlet and outlet airflow. The inlet airflow can enter from the
front or from below of the product. To allow cooling air to enter from the front, remove the air inlet covers of the integration unit.
The outlet airflow can exit the system module directly from the top or through a top duct. The top duct is available as an accessory.
Attach the top duct to the cabinet roof and back wall.

Steering the Airflow
Cooling air must be taken in through the ventilation gaps on the door and blown out at the top of the enclosure. To steer the hot air from
the power unit to the outlet at the top of the enclosure and prevent it from circulating back, follow these instructions.
1.
Install air guides in the gaps between the power unit and the cabinet walls. Place the air guides below the air outlet gaps at the
sides of the module.
