Definition of special terms
Energizer
– An appliance that is intended to periodically deliver
voltage impulses to a fence connected to it.
Fence
– A barrier for animals or for the purpose of security,
comprising one or more conductors such as metal wires, rods or
rails.
Electric fence – A barrier which includes one or more electric
conductors, insulated from earth, to which electric pulses are
applied by an energizer.
Fence circuit
– All conductive parts or components within an
energizer that are connected or are intended to be connected,
galvanically, to the output terminals.
Earth electrode
– Metal structure that is driven into the ground
near an energizer and connected electrically to the fence earth
terminal of the energizer, and that is independent of other
earthing arrangements.
Connecting lead
– An electric conductor, used to connect the
energizer to the electric fence or the earth electrode.
Electric animal fence
– An electric fence used to contain
animals within or exclude animals from a particular area.
Requirements for electric animal
fences
In accordance with Annex BB Section BB.1 of IEC
60335-2-76
Electric animal fences and their ancillary equipment shall be
installed, operated and maintained in a manner that minimises
danger to persons, animals or their surroundings.
Electric animal fence constructions that are likely to lead to the
entanglement of animals or persons shall be avoided.
WARNING!
Avoid contacting electric fence wires especially
with the head, neck or torso. Do not climb over, through or
under a multi-wire electric fence. Use a gate or a specially
designed crossing point.
An electric animal fence shall not be supplied from two
separate energizers or from independent fence circuits of the
same energizer.
For any two separate electric animal fences, each supplied from
a separate energizer independently timed, the distance
between the wires of the two electric animal fences shall be at
least 2.5 m (8'). If this gap is to be closed, this shall be effected
by means of electrically non-conductive material or an isolated
metal barrier.
Barbed wire or razor wire shall not be electrified by an
energizer.
A non-electrified fence incorporating barbed wire or razor wire
may be used to support one or more off-set electrified wires of
an electric animal fence. The supporting devices for the
electrified wires shall be constructed so as to ensure that these
wires are positioned at a minimum distance of 150 mm (6")
from the vertical plane of the non-electrified wires. The barbed
wire and razor wire shall be earthed at regular intervals.
Follow our recommendations regarding earthing.
A distance of at least 10 m (33') shall be maintained between
the energizer earth electrode and any other earthing system
connected parts such as the power supply system protective
earth or the telecommunication system earth.
Connecting leads that are run inside buildings shall be
effectively insulated from the earthed structural parts of the
building. This may be achieved by using insulated high voltage
cable.
Connecting leads that are run underground shall be run in
conduit of insulating material or else insulated high voltage
cable shall be used. Care must be taken to avoid damage to
the connecting leads due to the effects of animal hooves or
vehicle wheels sinking into the ground.
Connecting leads shall not be installed in the same conduit as
the mains supply wiring, communication cables or data cables.
Connecting leads and electric animal fence wires shall not cross
above overhead power or communication lines.
Crossings with overhead power lines shall be avoided wherever
possible. If such a crossing cannot be avoided it shall be made
underneath the power line and as nearly as possible at right
angles to it.
If connecting leads and electric animal fence wires are installed
near an overhead power line, the clearances shall not be less
than those shown in the table below.
