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 ➆ onto the cable as
shown. Arrange together the collet ➁, washer ➂,
gasket ➃ and earthing cone ➄ over 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 ➀ respecting the tightening
torque (table on page 3). Fix the bend relief - if
provided - onto the collet nut.
