Installation Guide Heating cables
1 Introduction
In this installation manual, the phrase "heating cable" refers
to heating cables in readymade lengths; heating cables
on drums; heating cables on mesh; and preshaped taped
heating cables.
2 Safety instructions
Heating cables must always be installed according to local
building regulations and wiring rules as well as the guide-
lines in this installation manual.
• De-energize all power circuits before installation and service.
• Residual current device (RCD) protection is required. RCD trip
rating is max. 30 mA.
• The screen from each heating cable must be earthed in
accordance with local electricity regulations
• Heating cables must be connected via a switch providing
all pole disconnection.
• The heating cable must be equipped with a correctly sized
fuse or circuit breaker according to local regulations.
3 Installation guidelines
• It is not recommended to install heating cables at tem-
peratures below -5°C.
• Heating cable bending diameter must be at least 6 times
the cable diameter. Do not bend connections.
4 Mechanical class
M1— For use in applications with low risk of mechanical
damage according to IEC 60800:2009, e.g. installed on even
surfaces and embedded in screeds with no sharp objects.
M2 — Can be used in applications with high risk of mecha-

• Never exceed the maximum heat density (W/m) for the
actual application.
• Caution! Do not use M1 classified cables in areas subject to
high mechanical loads or impact.
The presence of a heating cable must
• be made evident by affixing caution signs in the fuse box
and in the distribution board or markings at the power
connection fittings and/or frequently along the circuit line
where clearly visible (tracing).
• be stated in any electrical documentation following the
installation.
• Free end from cold lead must be protected by installer to
avoid water from coming in.

C — High mechanical strength according to IEC 60800:1992.
MMM — Marking for high mechanical protection class ac-
cording to NF C 32-330:2002
consequential or incidental damages including, but not limited
to, damages to property or extra utility expenses. An extension
of the warranty period following repairs undertaken cannot
be granted. The warranty shall be valid only if the WARRANTY
CERTIFICATE is completed correctly and in accordance with the

1) Heating cables/mats can be customized for the specific project, depending on voltage, required output, length of heating
cable and length of cold leads.
Note: It is the full responsibility of the installer/designer to use proper cold lead dimensioned for the purpose and assembly
sets that establish sufficient mechanical strength, flammability resistance and water tightness - and to design the heating
unit with correct output for the specific application to avoid overheating of the cable or building materials.
2) The heating cable shall only be installed in concrete or used while fully covered with non-flamable material eg. soil, water
or similar.
Regarding other types of applications please contact your local Danfoss sales company.
