CABLE HEATING CIRCUITS
GENERAL TERMS AND CONDITIONS

The heating part of the cable heating circuit may not be shortened or otherwise adjusted in any
way. Only the cold connection ends may be shortened, as needed.

The connector joining the cold connection end and the heating circuit must not be installed in a
bend. The heating cables may neither touch nor cross one another. The minimum distance
between the cables is 30 mm, and the diameter of a bend must be at least six times greater than
the cable’s diameter.

If the heating or power supply cables are damaged, they must be replaced or repaired by the
manufacturer, its service technician or a similarly qualified person in order to prevent a
dangerous situation from arising.

The heating cable must be supplied with electricity by means of a residual current circuit
breaker with rated actuating current of I∆n≤30mA. We recommend that each heating
unit/circuit be equipped with a separate residual current device.
 The heating cables may be stored at temperatures up to the resistance of the jacket (70°C) and
installed at a temperature of greater than -5. When in use, the cables may not be exposed to
temperatures exceeding 70°C.

Before and after laying the cables, it is necessary to measure the resistance of the heating
circuits. The measured values should be equal. Record the measured values in the certificate
of warranty. The tolerance of the measured values is ±5–10%.

Before and after laying the cables, it is necessary to measure the insulation resistance between
the heating conductor and the protective braiding. This measured value may not be less than
0.5 MΩ. Record the measured values in the certificate of warranty.

In case of any discrepancies, you should report these immediately to the manufacturer or
supplier and discontinue the work completely.

Before using the heating cable, it is necessary to check whether the data on the label is in
accordance with your requested product.
