NI 9921/9922 Outdoor IP Enclosure Installation Guide
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
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.

Press the grommet containing cable into the open cable gland.
4.
Press the two halves of the cable gland together until they lock together.
