The modular design of the kit lets you disconnect the devices at either the end of the drop
cable, or at the tap port located on the tap body, without disrupting communications to the
rest of the network. You can permanently disconnect a tap from a device by installing a tap
dummy load (1786-TCAP) at the tap end of the drop cable.
TIP
IMPORTANT
The 1786-TCAP is compatible only with the 1786-TCT2BD1 drop
cable. You can use the 1786-TCT2BD1 drop cable with the
1786-TPRT2T tap body.
No more than one tap should be disconnected at the body at a time and
no more than 10% of the taps in a network may be terminated with tap
dummy loads (1786-TCAP). Failure to adhere to these rules may cause
excessive network errors and/or loss of network communications.

ControlNet IP67 Tap and Cable Assembly Kit Installation Instructions 5
Why Use Sealed Media Components?
Sealed media components are ControlNet taps and TNC connectors, rated to IP67, that are
suitable for use in harsh environments. IP67 is an industry-standard protection rating that
describes the degree of protection provided to the components within the IP67-rated device.
The IP67 rating means that the components are dust- and water-tight and water-immersible.
While the tap bodies and TNC connectors in all three versions of the kit are water-tight, the
BNC connector in the 1786-TCT2BD1 kit is not. Use the BNC version of the kit
(1786-TCT2BD1) in applications in which you can mount the BNC connector inside a
cabinet, or in another non-harsh environment. The sealed tap body contained in all versions
of the kit can be mounted in any environment requiring an IP67 rating.
ATTENTION
Be sure to mate or terminate all connections. The taps and drop
cables are rated to IP67 only when properly mated. Unterminated
connections could be a source of contamination. Use the gray dust
caps supplied in this kit to terminate unused connections. Never
install extra taps in IP67 environments because there is no way to seal
and protect the tap connections.
The IP67 rating is guaranteed only when you use Rockwell
Automation-supplied connectors and heat-shrink tubing.

6 ControlNet IP67 Tap and Cable Assembly Kit Installation Instructions
Here are some example applications in which you would use the dust- and water-tight
ControlNet IP67 Tap and Cable Assembly kit:
ATTENTION
TIP
• robotic welding
• bottling
• automotive paint spray booth
• food processing (with washdown)
• metal processing
• wastewater treatment facility
• automotive manufacturing
• paper/pulp processing
IMPORTANT
Contact your Rockwell Automation representative for information on
chemical environments in which the taps are suited for use. Cutting
fluids and oils are not recommended for use with the taps.
Because TNC connectors have a greater operational vibration
tolerance than BNC connectors (10g vs. 2.5g), TNC connectors are
recommended for applications with a great deal of vibration, such as
stamping or automotive presses.
For information on how to plan and install your ControlNet cable
System, see the ControlNet Coax Media Planning and Installation Guide,
publication CNET-IN002.

Select a Location to Install Sealed Components
Use these guidelines to select where to install the components.
IMPORTANT
ATTENTION
IMPORTANT
• Be certain that the installation location is convenient for routing your cable and meets
the bend radius of the coax trunk line.
• Do not install sealed components so that the dropline cable is routed over any ac
power terminals on nearby modules.
ControlNet is an isolated system. Connectors and the shield must not
come in direct contact with a metal enclosure or other grounded
equipment. The 1786-BNC2TNC and 1786-TNCJI4 isolated bulkhead
connectors (available from Rockwell Automation) provide an isolation
from ground when properly installed.
Do not allow any metal portions of the tap, such as the universal
mounting bracket screws or connectors to contact any conductive
material. This contact could cause noise on the network.
Do not cut, lengthen, or substitute the drop cable supplied in this kit.
Doing so may diminish the integrity of your ControlNet network
connection.

10 ControlNet IP67 Tap and Cable Assembly Kit Installation Instructions
1. If your installation requires IP67-rated connectors, slide the heat-shrink tubing onto
the cable.
2. Place the crimp ferrule on to the cable.
3. Strip the cable using the 1786-CTK stripper tool.
4. Trim the center conductor to the required length as directed on the connector bag.
5. Push the flare tool onto the cable with a slight twisting motion (with sufficient inward
pressure to expand the braid).
41888
Push the flare/calibration tool gently and rotate
slightly onto the connector while applying pressure.
This will work the base of the connector underneath
the wire braid slowly.
6. Place the center pin over the center conductor.
IMPORTANT
Be certain that the center pin slips onto the center conductor completely.
The back shoulder of the center pin should be up against the white
insulation. If it is not, recheck the length of the center conductor.

7. With the center pin in place, use the crimp tool to crimp the pin into place.
The smaller hexagonal crimping notch is for crimping
the center pin onto the center connector.
41903
Check for braid strands that could
cause a short to center conductor.
8. Slide the ControlNet connector onto the cable. Push the connector body on tight
until the center pin tip is flush with the inner ground ring.
9. Slide the crimp ferrule over the three outer shields and connector base until it meets
the shoulder on the connector.
10. Using the crimp tool, crimp the ferrule. Position the crimp tool on the ferrule as close
as possible to the connector base and ferrule meeting line. Press the tool tightly
around the ferrule until the crimp tool allows release.
TIP
TIP
The larger hexagonal crimping notch is for crimping the ferrule which
holds the connector to the cable.
Many network problems are due to improperly installed connectors.
You should have tight-fitting connectors on the ends of all your
cables. Pull the connector to verify that it is attached. If it is loose or
comes off, snip off the connector and install a new one. The
connector should withstand a minimum 60lbs pull force if properly
installed.

11. Inspect the cable at the TNC connector end for any loose cable braids. Loose braids may
cause voids in the heat-shrink tubing.
Sometimes strands will be too long and
protrude out of the ferrule. Using the
Exacto blade, trim the excess length off
flush with the connector body.
12. Place the heat-shrink tubing with heat-active glue (provided in the IP67 Tap and Cable
Assembly Kit) over the TNC connector body and cable.
IMPORTANT
Use only the ACUM heat-shrink tubing provided in the kit. Do not
substitute other types of heat-shrink tubing. Substitutions may cause a
loss of the IP67 rating.
Apply Heat-shrink Tubing
1. Follow these guidelines when heating the tubing:
ATTENTION
a. Place the tubing against the shoulder of the TNC connector.
b. Allow the heat gun to come to a temperature of between 110 and 160 degrees Celsius.
c. Hold the cable assembly approximately 2 inches away from the heat exhaust area of
the heat gun while shrinking the tubing.
d. Continuously rotate the cable assembly around the heat exhaust area of the heat gun.
The entire process should take about 4 minutes.
Be careful when using heat guns. High temperatures can lead to burns,
risk of fire, or other property damage.
Publication 1786-IN017B-EN-P - May 2004
ControlNet IP67 Tap and Cable Assembly Kit Installation Instructions 13
e. Inspect the heat-shrink tubing to ensure that there are no voids where the glue has
incompletely melted. Voids could cause a loss of the IP67 rating.

2. Attach the trunk line to the tap. Tighten the trunk-line connector to 1 N-m (0.74
ft.-lbs.).
IMPORTANT
Be sure to install the dust cap on any unused connectors. Doing so will:
• prohibit the center conductor or the outer conductor from
inadvertently shorting to ground during installation
• provide partial environmental protection if a tap is left disconnected
for a prolonged time
