Powering the NI WSN-3226 Device
The NI WSN-3226 device can be powered by either an external power supply or four AA alkaline or
lithium batteries. Refer to the
requirements.
If both battery and external power are connected, the NI WSN-3226 functions from the external power
input. The device is designed to provide battery backup in the event of loss of external power and will
automatically switch to battery power when external power is lost.

Caution
Using the incorrect battery type causes an explosion risk. Do not use rechargeable batteries.
Refer to the
batteries.
Note
When using the NI WSN-3226 device on battery power, you should configure the device as
an end node so that it sleeps most of the time. Running a device configured in router mode from
battery power greatly reduces the battery life. The device ships from the factory configured as an end
node. For more information about how to switch the node from an end node to router mode, refer to
Configuring WSN in MAX, available from Start»All Programs»National Instruments»NI-WSN.
2.
Install four AA alkaline or lithium batteries in the device, making sure to install them with the
correct polarity. Figure 12 shows the battery polarity markings inside the device battery
compartment.
3.
Reinstall the battery compartment cover and tighten the retention screw.
