Practical tting instructions
It is very essential to follow this instruction
very carefully that when nished no connections are missing or wrong with the risk of
the cable not working or being overheated.
Therefore, read the entire instruction to the
end before you start.
A temperature of 150°C ± 30° is necessary to
skrink the crimp tubes. A hot air gun with a
temperature regulator is the most appropriate
tool.
However, a blow torch with a moderate ame
or a gas lighter can also be used.
Preparation of the heating cable
1. Remove the outer sheath from the cable
with a wire stripper.
Min. 50 mm
2. Pull the screen back over the cable and
cut away, (with a knife) the conductor
insulation.
Min. 35 mm
3. Using side-cutting pliers, carefully cut the
inner layer of the material between the
two conductors away, making sure not to
damage them when doing so.

4. Pull the conductors to the side and cut the inner layer
away so that it is ush with the rst layer of insulation.
5. Twist the conductors so that the remaining material
loosens.
6. Carefully cut away any remaning material and trim the
tips of the conductors. Cut a small triangle in the inner
material as shown in the diagram.
Min. 10 mm
7. Untangle the screen and then twist it together. Position it as shown in the diagram.Make sure that none of
the earth wires are in contact with the conductors.
8. Mount the crimp tube, type 3/1, L=15 mm, onto the
conductors.
9. Crimp the tubes
10. Pull the crimp tube, type 12/3, L = 20 mm over the
cable so that it meets the outer sheath at the one
end and protrudes at least 5 mm out over the inner
layer of material at the other end.
11. Crimp the tube.
12. Press the tube with at bit pliers between the con-
ductors until glue is visible.
