Note
The maximum power consumption specification is based on a fully populated
system running a high-stress application at elevated ambient temperature, and with
all C Series modules and USB devices consuming the maximum allowed power.

Wiring Power to the NI cDAQ-9132
The NI cDAQ-9132 requires an external power source as described in the
section. The NI cDAQ-9132 filters and regulates the supplied power and provides power to all
of the I/O modules. The NI cDAQ-9132 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-9132.
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-9132.
3.
Loosen the connector screw flanges and remove the power screw terminal connector plug
from the NI cDAQ-9132.
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.
