Setting Up the NI roboRIO
Wiring Power to the NI roboRIO
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.
Caution
Do
not
install or remove the power connector from the front panel of the
NI roboRIO
while power is applied.
2.
Connect the positive lead of the power supply to the V terminal of the COMBICON power
connector shipped with the NI roboRIO, and tighten the terminal screw. Figure 3 shows the
terminal screws, which secure the wires in the screw terminals, and the connector screws,
which secure the power connector on the front panel.

Powering On the NI roboRIO
When you apply power, the NI roboRIO runs a power-on self test (POST). During the POST,
the Power and Status LEDs turn on. The Status LED turns off, indicating that the POST is
complete. If the LEDs do not behave in this way when the system powers on, refer to the
LED
Indications
section.
