Elements may not touch or cross themselves or
other elements and must be evenly distributed
on areas.
The elements and especially the connection must
be protected from stress and strain.
The element should be temperature controlled
and not operate at ambient temperature higher
than 10°C in outdoor applications.

Calculating C-C distance
The C-C distance is the distance in centimetres from
the centre of one cable to the centre of the next.
C - C [cm] =
Area [m2]
x 100 cm
Cable length [m]
or
C - C [cm] =
Cable output [W/m]
x 100 cm
Heat density [W/m2]
• Max. C-C distance for roof and gutter systems
is 10 cm.
• Heating cable bending diameter must be at
least 6 times cable diameter.
• The actual cable length may vary +/- 2 %.

Planning the installation
Draw a sketch of the installation showing
• element layout
• cold leads and connections
• junction box/cable well (if applicable)
• sensor
• connection box
• thermostat
