Note For Ethernet-only use, attaching the antenna on the NI 9925 is optional; it does
not affect IP rating. However, attaching the antenna does offer protection to the
antenna connector on the enclosure.
12. Screw the antenna onto the external antenna connector until it bottoms out as shown in
Figure 6B.
13. Slide the antenna IP sleeve down the antenna and over the antenna IP boot until the antenna
IP sleeve touches the enclosure as shown in Figure 6C.
14. Connect an external IP rated RJ45 Ethernet cable to the external Ethernet connector on the
NI 9925 as shown in Figure 7. Refer to the IP Rated Cables section for information about
ordering and making custom IP rated RJ45 Ethernet cables.

NI 9925 as shown in Figure 7. Refer to the IP Rated Cables section for information about
ordering and making custom IP rated M12 power cables.
Note When either the external M12 power connector or external Ethernet connector
on the NI 9925 is not in use, cover that connector with the compatible end cap.
16. Connect the I/O cable(s) from the C Series module and route through one or both of the
I/O openings. Refer to the IP Rated Cables section for information about making and
connecting IP rated I/O cables.
17. Connect a ground wire to the chassis ground screw on the cDAQ chassis as described in the
NI cDAQ-918x/919x User Manual. Route the ground wire through one of the I/O openings,

as described in the Building IP Rated I/O Cables section. Terminate the ground wire to the
nearest earth ground or grounded structure.
Caution For I/O openings on the NI 9925 that are not in use, use the blank grommets
in the cable clamps to seal the openings and maintain an IP54 rating.
18. Reattach the enclosure cover by tightening the captive screws with a number 2 Phillips
screwdriver.
IP Rated Cables
This section contains information about using the field termination connectors that are shipped
in the NI 9925 outdoor IP enclosure kit to make your own cable lengths. You can order IP rated
cables and accessories from NI.
Building an IP Rated M12 Power Field Termination Cable
One M12 power female field termination connector kit is included in the NI 9925 kit for creating
a custom M12 power cable. To build an M12 field termination cable, complete the following
steps.
Caution Only use the connectors provided with the NI 9925 to build your cables.
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
connector.
1. Build the M12 power female field termination connector by connecting the positive lead of
the primary power supply to Pin 4. The pin number is marked on the inside of the field
termination connector, next to the respective terminal, as shown in Figure 8.
Figure 8. M12 Power Female Field Termination Connector Pinout
2. Connect the negative lead to Pin 3, as shown in Figure 8.
Note When the external M12 power connector on the NI 9925 is not in use, cover
the connector with the M12 power end cap.

Building an IP Rated RJ45 Ethernet Cable
The Ethernet field termination connector kit is included in the NI 9925 kit for creating a custom
IP rated RJ45 Ethernet cable. Refer to the SCPFE Wiring/Assembly Instructions document
included in the field termination connector kit for instructions about how to build an IP rated
Ethernet cable.
Caution Only use the connectors provided with the NI 9925 to build your cables.
Note When the external Ethernet connector on the NI 9925 is not in use, cover the
connector with the Ethernet end cap.
Building IP Rated I/O Cables
The two-piece clamp system, consisting of a cable clamp and a grommet, allows prefabricated
cables to route I/O out of the NI 9925. When the proper grommet is selected, the clamp system
meets a minimum IP rating of IP54. Grommets with two holes route two cables at once. Blank
grommets are also provided, allowing for custom cable configuration. For more information
about IP ratings, refer to the Understanding IP Ratings section.
Caution Only use the connectors provided with the NI 9925 to build your cables.
Note To ensure that the NI cDAQ-9181/9191 chassis meets specified requirements,
use one of the clamps to route ground outside of the NI 9925 outdoor IP enclosure.
Caution For I/O openings on the NI 9925 that are not in use, use the blank grommets
in the cable clamps to seal the openings and maintain an IP54 rating.
To use the clamp system, complete the following steps:
1. Choose the appropriately sized grommet for the cable diameter width. Blank grommets are
provided for use with custom cable sizes and to seal unused I/O openings.
2. Place the grommet around the cable(s) leaving enough length to go through the enclosure
hole and into the C Series I/O module, as shown in Figure 7.
3. Open the cable clamp. You may need to pry it open with a 0.125 in. flathead screwdriver.
4. Press the grommet containing the cable into the open cable clamp.
5. Press the two halves of the cable clamp together until they lock together.
6. Place the gasket over the clamp thread, thread the cable(s) through the enclosure hole, and
insert the clamp into the enclosure hole.
7. Secure the clamp system with the provided nut.

information about these accessories.
Understanding IP Ratings
Proper use and installation of an NI cDAQ-9181/9191 chassis in an NI 9925 outdoor IP54
enclosure provides a minimum IP rating of IP54 from outdoor and industrial environments. An
IP rating of IP54 protects against entry by dust particles and splashing water from all directions.
The two-digit ingress protection (IP) rating is defined by the IEC 60529 standard and specifies
the degree to which the enclosures protects against entry of dust (represented by the first digit)
and splashing water (represented by the second digit), as shown in Table 2.
