1.1 Clean cable jacket over a length of about 400 mm and cut cable end with a saw.
1.2 Remove jacket and take care of demanded length of return wires.
1.3 Wrap one layer of mastic onto the jacket, bend back the grounding wires and overlap
one layer with rest of mastic. Fix grounding wires with a cable tie.
1.4 Cover mastic with one layer Vinyl–tape up to the end of cable jacket.
1.5 Remove semi–con layer and check insulation diameter range.
1.6 Cut insulation acc drawing and bevel the edge.

3.1 Thoroughly clean the core insulation, using a suitable cleaner and a lint–free cloth.
3.2 Apply a thin layer of lubricant to the core insulation and the inside diameter of the cable
adapter.
10.1 Clean and apply lubricant to the insulating plug and the Tee connector interface.
10.2 Insert the insulating plug into the connector and engage the threads of the clamping
screw.
10.3 Tighten the insulating plug to a torque of 40 Nm, using a torque wrench and 24 mm
socket wrench.
10.4 Slide PST–tube onto the connector body and start shrinking 35 mm from the end
of the body.
10.5 Twist the screen wires and attach a lug.

5.1 If the conductor is aluminium, thoroughly wire brush the exposed conductor.
5.2 Immediately insert the conductor into the crimp barrel as far as it will go. Ensure
that the flat of the copper face is parallel to the face of the bushing.
5.3 Crimp the connector starting at the shoulder, as shown. Rotate the crimping tool
90 degrees for each successive crimp. Or use indent deep crimping according to
toolmanufacturer instruction.
5.4 Remove any excess grease that may come out of the crimp connector.
9.1 Push the Tee connector onto the bushing until it is fully seated.
9.2 Insert the long threaded end of the clamping screw through the hole of the crimp
connector and into the threaded hole of the bushing, taking care to avoid cross–
threading.
9.3 Tighten the clamping screw to a torque of 50 Nm, using a 22 mm socket wrench.
