Wiring Power to the NI cDAQ-9134
The NI cDAQ-9134 requires an external power source as described in the Power Requirements
section. The NI cDAQ-9134 filters and regulates the supplied power and provides power to all
of the I/O modules. The NI cDAQ-9134 has a primary power input, V1, and a secondary
power input, V2. The POWER LED on the front panel identifies the power input in use. When
the LED is lit green, V1 is in use; when the LED is lit yellow, V2 is in use.
Caution Do not connect V2 to a DC MAINS supply or to any supply requiring a
connecting cable longer than 3 m (10 ft). A DC MAINS supply is a local DC
electricity supply network in the infrastructure of a site or building.
Complete the following steps to connect a power source to the NI cDAQ-9134.
1. Make sure the power source is turned off.
2. Install the ferrite (National Instruments part number 711849-01, included in the shipping
kit) across the negative and positive leads of the power source, approximately 50 mm to
75 mm (2 in. to 3 in.) from the ends of the leads near the NI cDAQ-9134.
3. Loosen the connector screw flanges and remove the power screw terminal connector plug
from the NI cDAQ-9134.
Note Do not tighten or loosen the terminal screws on the power connector
while the power is on.
4. Connect the positive lead of the primary power source to the V1 terminal of the power
connector plug and tighten the terminal screw.

5. Connect the negative lead of the primary power source to one of the C terminals of the
power screw terminal connector plug and tighten the terminal screw.
6. Optionally, you can connect the positive lead of a secondary power source to the
V2 terminal and the negative lead to the other C terminal.
7. Install the power connector plug on the front panel of the NI cDAQ-9134 and tighten the
connector screw flanges.
8. Turn on the external power source(s).
The cDAQ controller uses V1 if the voltage across V1 and C is 9 V or greater. If the V1-to-C
voltage drops below 9 V, the NI cDAQ-9134 switches to V2. If the V2-to-C voltage is less
than 9 V, operation may be interrupted.
Note If the NI cDAQ-9134 is using V1 and a secondary power source is connected
to V2, there is a small leakage current on V2. The leakage current depends on the
V2-to-C voltage. Refer to the NI cDAQ-9134 Specifications for nominal values of
this leakage current
If the power source is connected to the power connector using long wiring with high DC
resistance, the voltage at the power connector may be significantly lower than the specified
voltage of the power source.
The C terminals are internally connected to each other but are not connected to chassis ground.
You can connect the C terminals to chassis ground externally. Refer to the Power
Requirements section for information about the power supply input range. Refer to the Safety
Guidelines section for information about the maximum voltage from terminal to chassis
ground.
