The terminating module is designed to be used with the modular plug dual terminator (shown in Figure 1)
terminates the modular plugs listed in Figure 2 to create a cable assembly. During termination, terminators
1320840-1 and 1320840-2 are capable of testing the cable assembly for electrical circuit continuity. Terminator
1320840-3 will not provide electrical circuit continuity testing. Read these instructions completely before using
the module.
NOTE
Dimensions in this instruction sheet are in metric units [with U.S. customary units in brackets]. Figures are not drawn to scale.
For detailed information about the modular plug dual terminator, refer to customer manual 409-10010.
For information on modular interconnection system products, refer to Catalog 82066.
Refer to the applicable application specification for cable stripping and module plug crimp requirements:

When reading this document, pay particular attention to DANGER and CAUTION statements.
DANGER
Denotes an imminent hazard which may result in moderate or severe injury.
CAUTION
Denotes a condition which may result in product or equipment damage.
Reasons for re-issue of this instruction sheet are provided in Section 7, REVISION SUMMARY.
1. DESCRIPTION
These terminating modules fit interchangeably into the modular plug dual terminator. Each module features
dual nest areas for positioning the modular plugs, inserters for terminating the contacts, and stuffers for
terminating the primary and secondary strain reliefs. Since each feature is independently adjustable, crimp
heights can be adjusted to meet FCC specifications.
2. INSTALLATION
1. Install the modular plug dual terminator according to 409-10010.

2. Disconnect the air supply.
DANGER
To avoid personal injury, always
disconnect the air supply
before attempting to install or remove the module from the
terminator. A lockout valve has been provided in the air line.
3. Remove the plastic guard from the module by removing four screws and two terminals from the limit
switch (refer to the module customer drawing for location).
4. For terminators -1 and -2 (only), refer to Figure 3, and:
a. Connect the cable from the automatic circuit tester to the back of the module, and tighten the
screws to secure cable.
b. Check that the two single-wire terminations on the limit switch to the left of the tester cable (viewing
from the back of the module) are firmly connected to the limit switch at the top-most and bottom-
most terminals (normally-closed position). Verify that the green wire of the tester cable is
connected to the terminator and to a suitable ground on an AC outlet.
c. Set up the automatic circuit tester according to 409-10010.
5. Position the module so that the T-slot at the top will slide onto the arm of the terminator so that the
module rests on the base plate of the terminator. Tighten the screws at the bottom front of the module,
securing the module to the base plate.
6. Re-connect the air supply to the terminator (regulated air supply of 551 to 689 kPa [80 to 100 psi] at
0.47 liters/sec [1.0 scfm]).
7. Re-install the plastic guard onto the module.
8. Run samples according to 409-10010 to inspect the crimp height and strain reliefs of each modular
plug.

9. Adjust the contact inserters (for proper crimp height measurement) and strain relief stuffers as follows
(refer to the applicable application specification for crimp height):
a. Lift the module ram mechanism off the module for ease in making adjustments.
NOTE
If adjustments must be made after module installation, first remove the module, and then remove the ram. See Figure 4.
b. Slightly loosen the two 8-32 socket head cap screws at the front of the ram (inserters and stuffers
are held to the ram by these screws) so that adjustments can be made.
10. Set the crimp height as follows:
a. Loosen the locking setscrews at the back of the ram head, and loosen the back-up setscrews
counterclockwise
at least one full turn (one full turn equals approximately 0.18 mm [.007 in.]).
b. Rotate the contact inserter adjustment screws
clockwise
to adjust the inserter downward until the
inserters are at the correct crimp height for the modular plug. One full turn equals approximately
0.18 mm [.007 in.]. Refer to the application specification for the crimp height.
c. Tighten the locking setscrews and back-up setscrews.

11. Adjust the primary strain relief stuffers as follows:
a. Loosen the 8-32 socket head cap screws enough to make the required adjustments.
b. Rotate the applicable primary strain relief adjustment screws (refer to Figure 4)
clockwise
to adjust
the primary strain relief stuffers downward. One rotation equals approximately 0.64 mm [.025 in.].
12. Adjust the secondary strain relief stuffers as follows:
a. Loosen the secondary strain relief adjustment screws enough to make the required adjustments.
b. Rotate the screws
clockwise
to adjust the secondary strain relief stuffers downward. One rotation
equals approximately 0.64 mm [.025 in.].
c. Hold
all
strain relief stuffers in their up-most position, and tighten the 8-32 socket head cap screws
(that hold the indenters and stuffers in place).
d. Re-position the ram on the module.
3. TERMINATING, TESTING, AND INSPECTING MODULAR PLUG
1. Strip the cable insulation outer jacket to the dimension given in Figure 2. Do not strip the insulation
from the individual conductors. Refer to the applicable application specification for shielded cable
stripping requirements.
2. Insert stripped cables into the modular plugs, and insert the cables and modular plugs into the module
nests. Make sure of the following:
— the cable conductors are oriented to the applicable contact slots before inserting the conductors
into the modular plugs,
— the cable conductors are bottomed in the contact slots of the modular plugs, and that they remain
bottomed throughout the cycling of the terminator, and
— the modular plugs bottom in the module nests; the modular plug release tab must snap firmly into
place.
3. Press the foot switch to cycle the terminator.
4. When termination is complete:
For terminators -1 and -2 (only), the tester will automatically examine the cable assembly and respond
with either a short tone or a long tone (refer to Figure 5). After the cable assembly is tested, hold the
cable assembly release down, and remove the cable assembly from the module.
CAUTION
Removing the cable assembly before a tone has sounded may cause good terminations to test as failures.
NOTE
Any coupled cable assembly may be tested or re-tested by inserting and latching the modular plugs into the nest areas and
pressing the TEST pushbutton.
For terminator -3, hold the cable assembly release down, and remove the cable assembly from the
module.
5. Inspect the crimps on the modular plugs using an indicator with a 0.25-mm [.010-in.] diameter needle-
point probe. Refer to the application specification for crimp height and other terminated modular plug
criteria.
Problems associated with bad cable assemblies should be recorded to aid in troubleshooting. Check
for the source of recurring problems in the following order:
a. Check the settings against the test cable.
b. Check that the correct combination of cable and plugs is being terminated.
c. Check crimp height and strain relief settings. If necessary, make corresponding adjustments to the
module.
d. Check that the spring plungers are all correctly resting on the contact probes.
e. Inspect and replace any defective mechanical tooling parts.
