Connecting an External Power Supply
You can optionally connect an external power supply to the NI-9361 to provide
current for the devices that you connect to the module. Install a 2 A maximum, fast-
acting fuse between the external power supply and the Vsup terminal.
Note Refer to the NI-9361 Specifications for more information about the
Vsup pins.
Caution Do not remove or install modules if the connected external
power supply is powered on.
