Connection Options
There are three options for connecting the fan of the PC to the CPU 41x-2 PCI (X3,
X4, or X5) - depending on the connector type. Together, the X3, X4 and X5
connections provide a maximum of 500 mA at 12 V. The current for the fan is
supplied from the PC motherboard or, if the PC is switched off, from the optional
external 24 VDC supply.
The X2 to X5 terminals are located on the smaller of the two printed circuit boards.
The terminals have the following meaning:

1. Remove the connector that is connected to the fan in the PC or is connected
from the motherboard or power supply and connect it to X3, X4, or X5,
depending on the connector type.
2. Three fan cables are shipped with the product. Select the appropriate cable
and insert it onto the terminal on the motherboard or power supply that has
been made available.
Use the 4-pin cable if the connection to the motherboard or the power supply is
a 3-pin connection.
3. Insert the other end of the cable onto X2 on the PC board of the CPU 41x-2
PCI.
Now, the PC fan will be operated by the CPU 41x-2 PCI, even if the PC is switched
off.
Connecting the Fan in Multi-Slot Operation
If you are operating more than one CPU 41x-2 PCI, connect the fan to one of the
CPUs 41x-2 PCI.
Warning
The CPU 41x-2 PCI, on which the fan is used always has to be connected to
the external 24 VDC power supply.
