INSTRUCTIONS FOR INSTALLATION AND CONNECTION OF ELECTRIC FENCES FOR ANIMALS.
The following safety information is part of the Australian standard AS/NZS 60335.2.76:2003 amend-
ment 2. Refer to AS/NZS 3014:2003 for full details on electric fence installation.
>Electric fences must be installed and operated so that they do not cause an electrical ha ard to per-
sons, animals or their surroundings.
>Construction of electric fences that is likely to lead to the entanglement of animals or persons is to be
avoided.
>An electric fence must not be supplied from two separate energi ers of from independent fence cir-
cuits of the same energi er.
>For any two separate electric fences that are each supplied from a separate independently timed ener-
gi er, the distance between the wires of the two fences must be at least 2 metres. If this gap is to be
closer, it must be effected by means of electrically non-conductive (insulating) material or an isolated
metal barrier.
>Barbed wire or ra or wire must not be electrified by an energi er.
>A non-electrified fence incorporating barbed or ra or wire may be used to support one or more off-set
electrified wires of an electric fence. The supporting devices for the electrified wires must be con-
structed so as to ensure that these wires are positioned at a minimum distance of 150mm from the ver-
tical plane of the non-electrified wires. The barb or ra or wire is to be earthed at regular intervals in
accordance with Thunderbird’s earthing recommendations.
>A distance of a least 10 metres must be maintained between the energi er’s earth electrode and any
other earthing system connected parts—for example mains power protective earth or telecommunica-
tion system earth.
>Electric fence connecting leads located inside buildings must be effectively insulated from the
earthed structural parts of the building, for example, use suitable high voltage insulated cable.
Impor an : always ensure metal parts of the building are effectively earthed.
>Electric fence connecting leads located underground must be run in suitable conduit of insulating
material or high voltage cable to be used. Care must be taken to ensure that the effects of animal
hooves or vehicle wheels (e.g. tractor) sinking into ground cannot damage connecting leads.
>Electric fence connecting leads must not be installed in the same conduit as the mains power supply
wiring, communication cables or data cables.
>Crossing with overhead power lines must be avoided wherever possible. If such a crossing cannot be
avoided it must be made underneath the power line and as near as possible at right angles to it.
>If electric fence connecting leads and wires are installed near an overhead power line, the clearances
must not be less than indicated in the table below.
Power line voltage - V Clearances - Metres
Up to 1,000 V 3
1,000 V - 33,000 V 4
Greater than 33,000 V 8
>
If electric fence connecting leads and wires are installed near an overhead power line, their height
above the ground must not exceed 3 metres. This height applies either side of the orthogonal projection

of the outermost conductors of the power line on the ground surface, for a distance of ;-
- 2 metres for power lines operating at nominal voltage not exceeding 1000V.
- 15 metres for power lines operating at a nominal voltage exceeding 1000V.
>Electric fences intended for deterring birds, household pet containment or training animals such as
cows need only be supplied from a low output energi er to obtain satisfactory and safe performance.
>For electric fences intended for deterring birds from roosting on buildings, no electric fence wire shall
be connected to an earth electrode. A warning sign must be fitted to every point where a person or
persons may gain access to the conductors.
>Where an electric fence crosses a public pathway, a non-electrified gate must be incorporated in the
electric fence at that point or a crossing by means of stiles must be provided. At any such crossing, the
adjacent electrified wires must carry warning signs.
>Any part of an electric fence that is installed along a public road or pathway must be identified at
frequent intervals by warning signs securely fastened to the fence posts or firmly clamped to the
fence wires.
>The si e of the warning sign must be at least 100mm x 200mm. The background colour of both sides
of the warning sign is to be yellow. The inscription on the sign is to be black and shall be either the
symbol shown (Fig. 1 ) or the words - “WARNING - ELECTRIC FENCE”
>The lettering must be indelible, be on both sides of the sign and in letters not less than 25mm in
height.
>Ensure at all times that a mains operated, ancillary equipment connected to the electric fence circuit
provides a degree of isolation between the fence circuit and the supply mains equivalent to that pro-
vided by the fence energiser.
>This energiser mus be ins alled in accordance wi h he s andard AS/NZS 3014:2003.
SPECIFICATIONS
Input Voltage 12.7V nominal - Maximum 20.0V
Input Current BD20 - 15mA (nominal) @12.5 volts: 30mA @ 6 volts

nised fencing wire for longer distances.
