On-board Fan Connector
The modules 3-pin fan connector powers, controls and monitors a fan for chassis ventilation.
Fan connector specification:
Part number (Molex) J3: 53261-0371
Mates with: 51021-0300
Crimp terminals: 50079-8100

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-module 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 output current.
