11. As necessary, remove the protective coverings from the ends being mated. Align the inner conductor with the protruding inner conductor from the previous section. Engage the coupling stud and rotate the driver ring to draw the connection together. Turn the driver ring by hand until the contact surfaces are snug.

CAUTION: TO PREVENT MISENGAGEMENT, THE INNER CONDUCTORS SHOULD BE ALIGNED WELL. The driver ring should turn freely during initial tightening.

12. Attach the inner conductor tool (#220335) to the inner conductor of the previous section, with the edge of the tool about 0.25 inch (6 mm) from the edge of the driver ring.

CAUTION: NEVER ATTACH THIS TOOL MORE THAN 0.5 INCH (12 MM) FROM THE DRIVER RING EDGE. This can result in damage to the inner conductor.

13. Use the driver-ring torque wrench (#220047) to tighten this connection to a torque between 250 and 275 ft-lb. The inner conductor tool is used to hold the inner conductor of the previous section stationary and the torque wrench is used to turn the driver ring. (Tightening is easier if the arm of the inner conductor tool is kept out of the way of the torque wrench arm.)

CAUTION: USE THESE WRENCHES ONLY. They are designed to prevent damage to the inner conductor and driver ring. Also, DO NOT ROTATE THE INNER CONDUCTOR TOOL during tightening. For a low-level installation, a tool rest is available to hold the arm of the inner conductor tool fixed.



14. This is a high contact pressure connection. After tightening, brush completely around the connection (between the driver ring and the inner conductors) to remove any small fillings that occur from the wiping action of the contacting surfaces. Use a soft horsehair brush or equivalent. 		15. Butt one end of the pretension gauge (#220043) against the strain insulator of the previously installed section and rotate the strain insulator until the edge of the driver ring is aligned with the opposite end of the gauge. This sets the proper strain on the inner conductor of the previously installed section.



16. Check the installation of the flange O-rings and reinsert them into their corresponding grooves as required. If necessary, draw a small bead of adhesive (#10866-122) to hold the O-ring in its groove.



Then apply a thin, approximately 1/64 inch (0.4 mm), continuous coating of Alumashield® (#203233-4) from the middle of the flange holes to the outer edge of the connector flange.

CAUTION: THE MATING FLANGE SURFACES AND THE INSIDE OF THE CABLE SECTIONS MUST BE CLEAN. Inspect these visually and remove any dirt, adhesive, or other foreign material before beginning the steps to join the outer conductors.

17. Carefully slide the outer conductor until the flanges are about 1 inch (25 mm) apart.
