Step 6: Attach External Cables
NI IP Rated Cables
Table 1 lists the optional cable accessories for use with the NI 9921/9922. Go to ni.com for more
information about these accessories.
Building and Connecting IP Rated Cables
You can order IP rated cables from NI or you can use the field termination connectors that are shipped
with the NI 9921/9922 outdoor IP enclosure to make your own cable lengths.
Caution Only use the connectors provided with the NI 9921/9922 when building your cables.
The following field termination connectors are included in the NI 9921/9922 kit for creating custom
cable connectors:
• One M12 power female field termination connector kit (connects to power)
• One M12 power end cap
The following field termination connectors are also included with the NI 9922:
• One Ethernet field termination connector kit. Refer to documentation included in the Ethernet field
termination connector kit for assembly instructions.
• One Ethernet end cap
• One M12 trigger male field termination connector kit (connects to trigger)
• One M12 trigger end cap
Note Be sure to route the wires through the plastic and rubber sealing grommets and the backshell
before connecting to the screw terminals on the M12 field termination connectors.
Building an M12 Field Termination Cable
To build an M12 field termination cable with the connector included with the NI 9921/9922, refer to the
following sections.
Female M12 Field Termination Cable
On the M12 power female field termination connector, connect the positive lead of the primary power
supply to Pin 4 and the negative lead to Pin 3.

1. Connect external IP rated cables to the external Ethernet connector and the external M12 power and
trigger connectors.
2. The two-piece gland system allows prefabricated cables to route I/O out of the NI 9921/9922.
When the correct cable gland is selected, it meets a minimum IP rating of IP54. For more
information about IP ratings, refer to the Understanding IP Ratings section. Glands with two holes
route two cables at once. Blank glands are also provided, allowing for custom cable configuration.
Note To ensure that the NI WSL-9000 Series device meets specified requirements, use one of the
glands to route ground outside of the NI 9921/9922 outdoor IP enclosure.
To use the two-piece gland system, complete the following steps:
1. Choose the appropriately sized grommet for the cable diameter width. Blank plugs are provided for
use with custom cable sizes.
2. Place the grommet around the cable.
3. Press the grommet containing cable into the open cable gland.
4. Press the two halves of the cable gland together until they lock together.
5. Place the provided seal over the thread and place the cable gland into the holes, as shown in
Figure 10.
6. Secure the gland with the provided nut.
Step 7: Attach the Cover
The cover of the NI 9921/9922 is equipped with captive screws. Use a #2 Phillips screwdriver to install
the cover as shown in Figure 11.
