Anti-condensation heaters
EF-HFE series
O P E R A T I N G
DESCRIPTION AND FUNCTIONING
The heaters are composed by an extruded aluminium heat sink
and a self-regulating PTC heating element; the heat dissipation
occurs through forced convection and irradiation.
The device is used to avoid the temperature falling below permitted
limits and to avoid the condensation inside electrical cabinets by
maintaining the temperature above the dew point.
Its functioning must be controlled by a thermostat to avoid
unsuitable temperatures being reached inside the electrical
cabinet.
INSTALLATION
WARNING
· The installation, running and maintenance of the heaters must be
carried out according to the instructions contained in this manual,
exclusively by experienced and qualified personnel, and must
observe national standards relating to electrical power supply
units;
· There must be an incorporated disconnect mechanism within the
power supply network;
· Verify that the environmental conditions and the voltage are within
the ranges specified in the data sheet of the product;
· The device cannot be repaired. If it is defective it must be
replaced entirely;
· The lateral distance from adjacent components must be greater
than 50mm;
· In order to guarantee the correct flow of air of the component
when in operation, a distance of at least 100mm must be kept
from the elements positioned above and beneath the heater.
Moreover, when it is in operation the heater must not be covered;
· During the installation you should ensure that the components
close to the heater do not deteriorate because of the heat
produced by the heater;
· For an optimal distribution of the heat the forced convection
heater must be installed in a vertical position, in the lower part
of the electrical cabinet, with the electrical connection at the
bottom;
· It must be possible to open the cabinet in which the heater is
mounted with a key or a tool;
· The heaters must not be used in the event of aggressive air in the
environment (due to abrasive or corrosive substances);
· Any use other than that for which the heaters were designed or
any amendments to the heaters are not permitted.
· Warning: Metal surfaces can be hot (after activation) -
Burn hazard!

MOUNTING
The heaters have a 35mm, DIN 46277/3 - EN50022 clip-on bar
mounting system.
To attach the heating element to the support insert the lower part
of the clip, which has an elastic element with a metal wire, to the
metallic rail, then exert upward pressure to bring the clasping device
on the upper part of the plastic clip into position (Diagram A).
ELECTRICAL CONNECTION
The heaters have a three-pole plug produced with pressure
terminals which are suitable for hosting only 60/75°C copper (Cu)
conductor and wire ranges between 0.5 ÷ 2.5mm
solid.
The connecting electrical wires must be suitable for their intended
use and sized on the basis of the characteristics of the heater (we
recommend the use of wires with an insulating silicon sheathing for
high temperature applications).
These terminals must be manually operated as the use of any
mechanical tool could damage the element (Diagram B). In the
start-up phase there is a high absorption of electrical current as a
result of the characteristics of the heating elements used (PTC).
Therefore it is necessary to use a time-delay or anti-surge fuse of a
suitable sizing.
