Fenix ELSR-M - Manual

N144/R01(17.04.08)
Self-regulating heating cables with
a non-heating service cable
ELSR-M-15-2-BO
ELSR-N-20-2-AO
ELSR-N-30-2-AO
GENERAL CONDITIONS
• The connector which connects the cold end and the heating circuit must not be
installed in a bend. The radius of any bend in the cable must not be shorter than
is set for the individual types. Bending should be applied to the flat side.
• If the heating cable or the supply cord is damaged, it must be replaced or
repaired by the manufacturer, their service technician or a similarly-qualified
person in order to avoid the occurrence of a hazardous situation. Do not install
the cables using nails and screws! Connection of the cables must only be carried
out by a qualified person.
• The heating cable must be fed through a Residual Current Device, with a
nominal actuating current of l ∆ n ≤ 30mA. We recommend that every heating
unit/heating circuit should be equipped with an independent Residual Current
Device.
• During operation, the cable must not be exposed to temperatures which are
higher than is set for the individual types.
• The installation must enable the disconnection of the cables at both poles.
• Before the installation and after it, the measurement of insulating resistance
between the heating conductor and the protective braiding must be carried out;
the measured value must not be lower than 0.5 MΩ. Write down the measured
values in the Certificate of Warranty.
• We will carry out a test of cable functionality at full line voltage after completion of
the installation.
• Announce any discrepancies to the producer or supplier immediately and stop all
work.
• Before the use of the heating cable, the label information must be checked to
make sure that they are in accordance with the required product.
• The supplier must inform the other suppliers involved in the construction work
about the placement of the heating unit and about the risks which arise from it.
• Any use of the cable other than what is described in these instructions needs to
be consulted with the producer.
• The shielding of the heating cable must be connected with a protective conductor
according to valid regulations.
• At low temperatures, if the cable is not flexible enough, it is possible to heat it.
The temperature during the installation must not drop under -10°C or -30°C
according to the type of cable.
• The surface where the heating cables will be installed must be clean and free of
any sharp objects.
• The self-regulating heating cables won’t switch off completely, even during
summer temperatures, and so we recommend their regulation with a thermostat.
