6.4.8.1 Use logic control output
The connected devices can be powered with the internal 10 V with the connected
device connected to a logic output.

If the connected devices require a different voltage, these devices can be powered
with an external power source. The negative output of the external power source
must be connected to the GND of the system; the positive output is connected to
the device.
