1. Strip the cable according to the dimensions
indicated in the table on page 3. For connectors
with solder contacts, the length L should be
reduced to correspond with interior contact
lengths.

2. Slide the following onto the cable: bend relief if
provided, collet nut ➀, collet ➁, metal washer ➂
flexible gasket ➃, and earthing cone ➄. In the
case of a shielded cable, fold back the shielding
around the whole circumference of the earthing
cone.
3. Slide the elbow inner shell ➆onto the cable as
shown. Arrange together the collet ➁, washer ➂,
gasket ➃and earthing cone ➄over the cable.
Verifying that the shield remains around the
earthing cone circumference, cut off any surplus.
Verify also that the cable jacket remains correctly
located under the flexible gasket. Fit the collet
subassembly into the elbow inner shell ➆. Screw
on the collet nut ➀respecting the tightening
torque (table on page 3). Fix the bend relief - if
provided - onto the collet nut.

4. For solder contacts, solder the conductors to the
contacts, making sure that the insulator ➇and the
cable remain clean.

5. Fit the insulator assembly into the slot of the
elbow inner shell ➆. Position the midpiece ➅on
the insulator ➇. The window must be positioned
exactly on the insulator’s notch. Make sure that
the insert carrier forms a cylinder with the elbow
inner shell.

6. Fit the pre-assembly into the connector housing ➉
by holding the collet nut, and giving it a slight
rotation and pressure until the midpiece’s key is
inserted into the housing’s slot situated under the
red keyway dot.
Using the appropriate tooling (see catalog), to
ensure that internal components do not turn in
housing, screw on the hex cap with appropriate
torque (see page 3). For plugs F●●, hold the front
nose of the plug with plier DPF to ensure that the
internal components do not turn in the housing.

4. For crimp contacts, Fix the appropriate positioner
onto the crimping tool (see catalog) and set the
selector to the number corresponding to the AWG
of the conductor used.
Fit the conductor into the contact; make sure that
conductor is visible through the contact's
inspection hole. Slide the contact-conductor
assembly into the open crimping tool; make sure
that the contact is pushed fully into the positioner.
Close the tool.
Remove from crimping tool and check that
conductor is secure in contact and shows in
inspection hole. Arrange the contact-conductor
assemblies according to the insert marking (see last
page for example), avoiding any twisting of the
conductors.
Fit the contacts gently into the insulator ➇; check
that no conductor overlaps another and push the
contacts into the insulator. Check that all the
contacts are correctly located in the insulator: 1) by
verifying the alignment of the contacts at the front
of the insulator and 2) by gently pulling on the
insulator; the contact alignment must remain in
correct position.
