Installing the fan
1. Position the replacement fans on the fan support. Note the direction of the airflow from
bottom to top (the arrow on the fan must point to the inside of the module).
2. Push the fan support and fan into the device. The connecting cables must not be crushed
when doing this.
3. Tighten the oval head screws at the fan support (tightening torque: 1.8 Nm).
4. Insert the connecting plugs so that you can hear them engage.
5. Put the fan cover on. The connecting cables must not be damaged when doing this.
6. Screw the countersunk screws on the fan cover and tighten them crosswise (tightening
torque: 1.8 Nm).
