Description
The cable ducts’ height is less than 40 mm / 1.57 in.
The cable ducts’ height is greater than 40 mm / 1.57 in.
The length of the required spacer is calculated as follows:
L = H - 40 mm / 1.57 in.
L = length of the spacer
H = height of the cable duct
If more than two devices (even when the minimum vertical clearance of 100 mm is observed) are installed one above the other, additional ventilation measures are required to ensure even temperature distribution. The illustration below shows the minimum clearance in the event that the DIN rails are not installed on spacers.
