Ready-making of the heating cable
The heating cable is stripped over a 1.
length of 90 mm.
The screen is released and twisted. 2.
Following this, remove the outmost
80 mm of the primary insulation. Use
knife.
The core material is removed from 3.
the conductors, also from the
outmost 80 mm. Be careful no to
damage the conductors.
Crimp tube 4/1, L=70 mm is pulled on 4.
to the two stripped wires.
The crimp tube is crimped down from 5.
the core material towards the cable
end.

Ready-making of the heating cable
Crimp tube 9/3, L=20 mm is pulled 6.
in over the two conductors, all the
way to the twisted screen in order to
cover approx. 10 mm of the primary
insulation and approx. 10 mm of the
conductors.
The crimp tube is crimped down and 7.
immediately after this the outmost
10 mm are squeezed together on the
middle with flat pliers.
Yellow/Green, L=50 mm tube is 8.
pulled in over the twisted screen.
Now the heating cable is ready for 9.
direct connection.
