3. Installation of the cold lead to the heating cable with the connection set
3.1 Slide 127mm tube and 203mm black
heat shrinkable tube over end of the plug-
in cord.
3.5 Lightly score completely around and
then pull down inner jacket. The length is
45mm.
3.3 Bend heating cable to break jacket at
score then peel o outer jacket.
3.7 Skive matrix material from conductors
with utility knife.
3.10 Trim the front bus wires to 7mm.
3.12 Remove release paper from strips,
wrap one strip of mastic around the black
wire against the end of the splice.
To provide a water block, then repeat
for the white wire squeeze the mastic
together.
3.14 Make sure the adhesive will appear
at both ends. Immediately after shrinking,
pinch rst one end of the tube and then
the other end.
3.16 Wrap black cloth tape evenly around
crimp and splice. Cover crimp completely.
3.18 Plug the grey cap onto the opposite end of the cable. Never
shortcut the cable ends. The jelly will ensure the insulation of the
connection.
3.9 Center the 15mm × 25mm
heatshrinkable tube over the end of
heating cable as
shown. Immediately after shrinking, pinch
with pliers between wires while tube is still
hot. Hold for 10 seconds to ensure seal.
3.2 Lightly score completely around and
then down outer jacket. The length is
70mm.
3.6 Bend heating cable to break jacket at
score, then peel o inner jacket.
3.4 Unravel the braid back to the out
jacket. Straighten the braid and twist into a
“pigtail”.
3.8 Slide the 3.2mm × 25mm shrink tubes
over bus wires. To shrink tubing move
heat source continuously from side to
side. While shrinking, ensure that tubes
remain up against black.
3.11 Use insulated bus wire crimps or
a crimp tool to connect black and white
wires to bus wires of heating cable.
Polarity does not matter.
3.13 Center the 127mm heat shrinkable
tube over the splice. Shrink the tube
completely.
3.15 Use crimp tool to connect braid to
ground wire.
3.17 Center the 203mm heatshrinkable
tube over and shrink the tube completely.
Make sure the ring of adhesive will appear
at both ends. Total heating time should be
about 3 minutes.
