1. Slide clamp nut and ‘0’ ring over cable.

2. Trim cable to dimensions shown being careful not to nick the braid.

ABC

6,35 (.250)

4,78 (.188)

3,18 (.125)

3. Thumb braid out radially to expose the cable dielectric.

4. Slide sleeve over dielectric and under braid until sleeve is flush with braid. N.B. When using

cables with inflexible jackets it is permissible to make two 3,17 (.125) long longitudinal slits in the

outer jacket.

5. Trim braid flush with flange of sleeve.

6. Trim back dielectric to dimension shown.

7. Tin center conductor (DO NOT OVER TIN).

8. Fit insulator over center conductor with counterbore in direction shown.

9. Place a small solder preform made from 0,26 - 0,31 (.010 - .012) dia. (28 swg) multi-core solder

in rear of contact on center conductor. Heat to make solder connection ensuring shoulder of

contact is flush against rear insulator. Do not allow solder to protrude outside spill hole.

10. Fit front insulator if not part of body.

11. Thread on body and tighten clamp nut to 1.02 Nm (9 in. lbs.).
