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
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.
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.
This energizer is not intended for use by persons (including
children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they
have been given supervision or instruction concerning use of
the energizer by a person responsible for their safety.
Children should be supervised to ensure that they do not play
with the energizer.
Electric animal fence constructions that are likely to lead to
the entanglement of animals or persons shall be avoided.
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.
6
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.
Minimum clearances from power lines for electric animal
fences
Power line voltage
1000 V
1000 V to 33,000 V
33,000 V
If connecting leads and electric animal fence wires are
installed near an overhead power line, their height above the
ground shall not exceed 3 m (10'). This height applies to
either side of the orthogonal projection of the outermost
conductors of the power line on the ground surface, for a
distance of:

2 m (6'6‛) for power lines operating at a nominal
voltage not exceeding 1000 V.

15 m (50') for power lines operating at a nominal
voltage exceeding 1000 V.
Electric animal fences intended for deterring birds, household
pet containment or training animals such as cows need only
be supplied from low output energizers to obtain satisfactory
and safe performance.
In electric animal fences intended for deterring birds from
roosting on buildings, no electric fence wire shall be
connected to the energizer earth electrode. A warning sign
shall be fitted to every point where persons may gain ready
access to the conductors.
Where an electric animal fence crosses a public pathway, a
non-electrified gate shall be incorporated in the electric
animal fence at that point or a crossing by means of stiles
shall be provided. At any such crossing, the adjacent
electrified wires shall carry warning signs.
Clearance

4 m (13')
