Installation Instruction
ECiceguard 18 self-limiting heating cable
ECiceguard 18 is a self-limiting cable, which is
mainly used for ice and snow melting on roofs and in
gutters and down pipes.
Self-limiting heating cables are designed with a
temperature dependant resistant element between
two parallel copper conductors.
When the conductors are connected to the
mains, a current goes through the temperature
dependant resistant element which will then heat. As
the element is heated the resistance value rises caus-
ing the current to decline and heating is reduced.
This explains the self-limiting effect.
This limiting of the output takes independently
place on the entire length of the cable according to
the actual ambient temperature.
If the ambient temperature rises the heating
effect of the cable is reduced. Due to this self-limiting
capability, overheating of the cable can be avoided,
also if two heating cables are touching or crossing.

Safety instructions
Heating cables must always be installed accord-
ing 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 regula-
tions
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.

As self-limiting heating cables always give off a
small amount of effect, it is recommended to con-
nect the heating cable via a thermostat to disconnect
the mains when heating is not required.
ECiceguard secures against ice formations in
roof gutters:
•
No water damages on/in the house
•
No falling icicles or icebound roof gutters
•
No risks for pedestrians
•
No repair costs after winter
For further information about application of
self-limiting heating cables or other Danfoss products,
please see the Danfoss heating cable compendiums.

Never exceed the maximum heat density (W/m)
for the actual application.
Caution! Do use M2 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 con-
nection fittings and/or frequently along the circuit
line where clearly visible (tracing);
•
be stated in any electrical documentation
following the installation.
