To connect a standard 3-pin connector fan to the module, use one of the following adaptor cables:
KAB-HSP 200 mm (PN 96079-0000-00-0)
KAB-HSP 40 mm (PN 96079-0000-00-2)
If the input voltage is below 13 V, the maximum supply current to the on-board fan connector is 350 mA. The
maximum supply current is limited to 150 mA if the input voltage is between 13 V and 20 V.
Always check the fan specification according to the limitations of the supply current and
supply voltage.
