10. Remove the plastic mast butt adaptor section of the mast base assembly (if fitted) by
unscrewing the M6 Phillips head screw on the side. Straighten the cable as much as
possible then carefully slip the first 1.2 m length of heatshrink over the cable until the end
of the heatshrink tube covers and overlaps the semi-conductive tape (over the black
outer sheath) by at least 3 cm (Figure 26). Ensure that the semi-conducting tape is not
damaged or lifted during this process. Using a gas torch or heat gun, carefully shrink the
lower end of the heatshrink into the correct position and gradually work up towards the top
of the heatshrink ensuring there are no pockets of air trapped under the heatshrink.
Note: Ensure that the heat gun or gas torch is not pointed in the same area for too long as this
will burn the heatshrink. Also be careful around the ends of the tube as too much heat will
damage the black outer sheath, semi-conductive tape and black insulation.
Figure 26.
11. Place the 2nd 600 mm heatshrink tube into place over the cable, again ensuring that
the semi-conductive tape is not damaged, overlapping the previous heatshrink tube by
approximately 6 cm. Shrink about 7 cm of the upper end of the heatshrink into place so that it
will sit flush with the base of the plastic mast butt adaptor when fitted back into place. Note:
That there is a mark on the lower finial connector indicating where the heat-shrink needs to
be fitted to. Shrink the rest of the heatshrink from the top down, ensuring that it overlaps the
previous piece of heatshrink by at least 6 cm Figure 27. Ensure the rest of the heatshrink has a
smooth overall finish. Note: Do not bend the cable while the heat shrink is still hot.
Note: If required, feed the cable through the mast sections & guying ring prior to refitting the
mast butt adaptor. Replace the plastic mast butt adaptor section of the mast base assembly
back onto the lower finial connector and ensure that the M6 Phillips head screw is tight and secure.

12. The lugged HVSC Plus is now ready to be connected to the base of the Guardian Plus
terminal. Screw the terminal onto the completed terminal base assembly and secure with
the supplied M6 locking grub screw.
