Safety instructions

Heating cables must always be installed according to
local building regulations and wiring rules as well as the
guidelines 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.
• Never exceed the maximum heat density (W/m or W/m²)
for the actual application.
3 Installation guidelines
• It is not recommended to install heating cables at
temperatures below -5°C.
• Heating cable bending diameter must be at least 6 times
the cable diameter. Do not bend connections.
4 Mechanical class

applications, on steel reinforcing grids, in concrete with
sharp stones, roof and gutters, etc.
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
according to NF C 32-330:2002
