FIRE HAZARD.Heat guns and flameless heating
tools can cause fire or explosion in hazardous
areas. Be sure there are no flammable materials
or vapors in the area before using these tools.
Follow all site safety guidelines when working in
hazardous areas.
Component approvals and performance are based
on the use of specified parts only.
HEALTH HAZARD.Overheating heat-shrinkable
tubing or SolderSleeves will produce fumes that
may cause irritation. Use adequate ventilation and
avoid charring or burning. Consult MSDS RAY3122
and RAY5103 for further information.

• Wrap 1/4 inch (6 mm) wide masking tape 1-1/4 inch
(31 mm) away from roped cable end.
• Cut back rope fibers to tape edge as shown. Do not
damage the four wrapped (red, yellow, gold) wires.
• Us a butane lighter to remove the insulation
from the two gold wires. Move the flame
slowly over the last 1/2 inch (13 mm) of
each gold wire.
• Remove the residue from
gold wires using 28 AWG
slot on wire stripper.
• Remove masking tape closest to roped cable end and
unravel rope fibers.
• Using needle nose pliers, pull the four wires from their
grooves exposing 5/8 inch (16 mm) of the grooved core.
• Cut off 1/2 inch (13 mm) of the core without
damaging the wires.
• Grasp the wire tips with the needle nose pliers.
• Pull the wires back into their grooves and
lightly tug to straighten without stretching.
• Carefully strip 1/4 inch (6 mm)
of insulation from each of
the red and yellow wires
(use 26 AWG slot).

• Use the ohmmeter to measure the
resistance between the gold wires. The
resistance must be greater than 20
megohm (meter may read: ∞, O.L., etc.).
• If the measurement is less than 20
megohm, check that the cable is not
wet or contaminated, and make sure
the wires are not touching each other.
Repeatmeasurement.
• Note the large tab cutout around
rim of connector. Position the
large tab at 12 o’clock position,
seebelow.
• Use permanent ink marker to mark
flat portion of connector body
behind the large tab.
• For the pin connector (Part A) only,
slip the spinner ring, large hole first,
onto the connector.
• Attach TT-MET-MC and TT-FET-MC
(Parts F and G) to socket and pin
connector (Parts B and A) to use
as a holder to avoid burning fingers
while applying heat.
• Keep wires in the same order that they
exit from the cable end.
• Slide a SolderSleeve splice (small end
first) onto each wire, all the way to the
cable end.
• The solder ring must lie over bare
conductor, not insulation.
• Wire ends
must extend
beyond the
solder rings.
• Once yellow wire is aligned correctly to the mark on
connector body, the red wire will be opposite to it
and all wires will be in their correct positions.
• Orient the connector and push
aligned connector posts into the
SolderSleeves.
• Verify the SolderSleeve ends
are inside the back of
the connector.
• Make sure the solder
bands are in contact
with connector posts
and the wires.

• Heat the SolderSleeves until they have shrunk fully and
the solder rings have melted and flowed. Keep the heat
source moving to avoid charring the connector.
• Carefully remove assembly from heat. Hold connector
and cable steady and allow to cool. Moving solder joint
when hot can weaken the connection.
• Push the taped rope end toward the
connector to remove any slack in
therope.
• Heat shrink 1/4 inch (6 mm) of the tube onto the
connector, moving the heat source around the tube to
heat evenly.
• Leave a small gap (1/16 inch) (1.5 mm) between the tube
and the ribbed section of the connector.
• Do not overheat. The tube may slip off of the connector
if it is overheated.
• Allow to cool before proceeding.
• Slide an SCT labeled heat-shrinkable tube over the assembly.

• Finish shrinking the tube, starting at the end opposite
theconnector.
• Do not apply heat directly to the rope.
• Heat the tubing end until adhesive melts and beads
on the rope.
• Inspect the exposed adhesive at the tubing/rope
interface. If a void is visible, use a glove or rag to
squeeze the tube slightly and fill the void with
molten adhesive.
• Keep heating the tubing section in the middle of tube
until fully recovered.
• Avoid reheating the already shrunk section on the
connector body.
• Proceed to the next step before the tube cools.
• While the tubing is still hot, place tubing in the smaller
opening of the crimp tool (1). Align opening with
SolderSleeve/cable area. Crimp SCT tubing to cool and
seal. Open and rotate crimp tool 90 degrees and crimp
again to ensure proper adherence to the cable.
• While the tubing is hot, align the large opening of the
crimp tool (2) over the roped portion of cable (with the
end of the tube halfway into the tool). Fully close
thetool.
• If the tubing has moved more than 1/8 inch (3 mm) off
the threaded connector, push the hot tubing back to the
original position while supporting assembly using
“holder” end termination. You may have to reheat the
tube. Hold the crimp tool in place while it cools the tube.
• Apply heat to tubing one last time to soften the creases
made by the crimp tool. Do not overheat.
• Remove the crimp tool and let the assembly
finishcooling.
• Allow the assembly to fully cool.
• Remove the end termination.
• For the pin connector, the spinner ring must turn freely.
If necessary, gently use pliers to break it free.
CAUTION: Burn Hazard. Do not get hot adhesive on
your bare skin. The hot adhesive will burn your
skin.

Electrical Test
• Attach the mating test-tool-half to the connector to be tested.
• If both cable ends have connectors, attach a mating end
termination at the opposite end. If there is no connector on the
opposite cable end, prepare it according to steps 1 through 6 and
twist together wires 1 & 2. Also join wires 3 & 4.
• Use an ohmmeter to measure the resistance between the test
tool posts.
• The resistance between the 2 longest posts or the 2 shortest
posts should be ≈ 2.5x cable length (ft) (i.e. A 100 ft. (30 m)
cable should measure ≈ 250 Ω between the two longest posts
and ≈ 250 Ω between the two shortest posts.)
• The resistance between the 2 intermediate length posts should
be greater than 20 megohms.
• If the assembly fails any of the resistance tests;
1) Check the twisted wires at the opposite able end.
2) If necessary, cut off and discard the connector and install a
new one.
• Before mating the connector assemblies, slide the unlabeled
shrink tube (Part E) onto one of the cables. Connect the pin
and socket connectors together firmly. Center the unlabeled
shrink tube over the pin/socket connection. Heat shrink
the tube over the connection, beginning in the center and
shrinking towards the ends until the tube fully conforms to
the shape of the connection and adhesive flows from each
end of the tube.
•
• Avoid overheating Part E. The thin wall unlabeled shrink
tubing requires less heat than the SCT cable shrink tubing.
• Let the entire connector area cool before handling the cable.
Note: Do not leave connector open to environment. If the
connector becomes wet or contaminated, it will need to
bereplaced.
CAUTION: Burn Hazard. Do not get hot adhesive on
your bare skin. The hot adhesive will burn your skin.
