1.8 Replacing the fan kit
1. Disconnect the power supply to the B&R industrial PC (unplug the power cable!). Isolate from all potential
sources of electrical power!
2. Touch the housing or ground connection in order to discharge any electrostatic charge from your body.
3. Press in the indicated latching mechanisms ➀ while pulling out the fan kit ➁ at the same time.
4. A new fan kit can now be installed. Align the fan kit parallel to the Panel PC and press it in until it latches.
Make sure the fan kit is inserted so that the connections match up.
5. If a fan kit is being installed for the first time (i.e. fan kit previously not used in device), then it must still be
programmed. To do so, follow the instructions in the "Programming fan kit data" section.
If a fan kit has been removed from the device and is not being replaced, then its data must be deleted. To do
so, follow the instructions in the "Deleting fan kit data" section.
Information:
If a fan kit has been replaced, then an incorrect serial number will be displayed. To display the
correct serial number, the fan kit data must be deleted and reprogrammed.
6. After the fan kit has been programmed, the BIOS default values must be loaded and the settings saved. For
additional information, see "Save & Exit" on page 223.
