Self-regulating heating cables with

a non-heating service cable




• The connector which connects the cold end and the heating circuit must not be

installed in a bend. The radius of any bend in the cable must not be shorter than
is set for the individual types. Bending should be applied to the flat side.

• If the heating cable or the supply cord is damaged, it must be replaced or

repaired by the manufacturer, their service technician or a similarly-qualified
person in order to avoid the occurrence of a hazardous situation. Do not install
the cables using nails and screws! Connection of the cables must only be carried
out by a qualified person.

• The heating cable must be fed through a Residual Current Device, with a

nominal actuating current of l ∆ n ≤ 30mA. We recommend that every heating
unit/heating circuit should be equipped with an independent Residual Current

• During operation, the cable must not be exposed to temperatures which are

higher than is set for the individual types.

• The installation must enable the disconnection of the cables at both poles.

• Before the installation and after it, the measurement of insulating resistance

between the heating conductor and the protective braiding must be carried out;
the measured value must not be lower than 0.5 MΩ. Write down the measured
values in the Certificate of Warranty.

• We will carry out a test of cable functionality at full line voltage after completion of

the installation.

• Announce



to the producer or supplier immediately and stop all


• Before the use of the heating cable, the label information must be checked to

make sure that they are in accordance with the required product.

• The supplier must inform the other suppliers involved in the construction work

about the placement of the heating unit and about the risks which arise from it.

• Any use of the cable other than what is described in these instructions needs to

be consulted with the producer.

• The shielding of the heating cable must be connected with a protective conductor

according to valid regulations.

• At low temperatures, if the cable is not flexible enough, it is possible to heat it.

The temperature during the installation must not drop under -10°C or -30°C
according to the type of cable.

• The surface where the heating cables will be installed must be clean and free of

any sharp objects.

• The self-regulating heating cables won’t switch off completely, even during

summer temperatures, and so we recommend their regulation with a thermostat.
