Setting Up the NI roboRIO
Connecting to Power
The NI roboRIO requires an external power supply that meets the specifications in the
Power
Requirements
section of the
NI roboRIO Specifications
. The NI roboRIO filters and regulates
the supplied power and provides power for all of the I/O and user voltage. The NI roboRIO
has one layer of reverse-voltage protection.
Complete the following steps to connect a power supply to the chassis.
1.
Ensure that the power supply is turned off.
