In this installation guide for the R3G500-FA28-03 EC Centrifugal Fan, it's crucial to pay attention to the tightening torque specifications. For PVC cables, the recommended torque is 1.5 ± 0.2 Nm. However, if you're using different cable materials, be prepared to adjust the torque accordingly. Ensure that the minimum cable diameter is 4 mm and the maximum is 10 mm, requiring a tightening torque of 4 ± 0.6 Nm.

Additionally, keep in mind that the inlet ring, part number 50355-2-4013 with a pressure tap (k-factor: 375), is not included in the delivery. Also, observe the max clearance for screws, which is 20 mm, to secure a proper installation. Follow these guidelines for a successful setup and operation of your centrifugal fan.
