Step 2
1. Remove 225 mm of the insulation screen.
2. Remove 77 mm of core insulation.
3. Cut a 45° chamfer onto the end of the cable
insulation.
Step 3
1. Thoroughly clean the core insulation, using a suitable
cleaner and a lint-free cloth.
2. Wrap several layers of electrical tape over the end of
the conductor.
3. Apply a thin layer of lubricant to the core insulation
and the inside diameter of the cable adapter.
4. Slide the cable adapter onto the cable, black end
first, until the grey end is 85 mm from the end of the
cable. Remove the electrical tape from the conductor.
Step 4
1. If the conductor is aluminum, thoroughly wire brush
the exposed conductor.
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.
3. Crimp the connector starting at the shoulder, as
shown. Rotate the crimping tool 90° for each
successive crimp.
4. Remove any inhibitor that may come out of the crimp
connector.
Step 5
1. Clean the outer surface of the cable adapter and the
interior of the cable end of the tee connector with a
lint-free cloth. Apply a thin layer of lubricant to both
surfaces.
2. Push the tee connector over the cable adapter as far
as it will go. Ensure that the hole in the top of the
crimp connector is visible through the interface end
of the tee.
3. Connect one of the screen wires to an earthing eye
on the tee connector.
