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.

4| ni.com | NI cDAQ-9134 Safety, Environmental, and Regulatory Information

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.

Caution Removing power without shutting down the NI cDAQ-9134 for Windows

can corrupt the embedded Windows system drive.
