The energiser displays the voltage on its terminals. It is a guide as to the condition of the
fence. A circular segment in the top centre of the display flashes with every energiser pulse.
If the battery voltage falls to approximately 11.5V at low battery indication will be dis-
played. Once the battery voltage falls to 11V the energiser will stop and the low battery
segment will be continuously on. If the battery voltage falls below approximately 8V, the
energiser will shut off completely. The energiser will start operating normally again when
the battery voltage exceeds 12V. These cutouts are intended to protect your battery.
These energisers have built in self testing. If there is a problem with the unit you will see an
error code displayed. Return it for repair. If the displayed voltage is low, turn off the unit,
disconnect the fence from the energiser, then turn it back on. If the displayed voltage is
around 8.0kV, there is a problem with the fence. If the displayed voltage is still low, there
may be a problem with the energiser.
INSTRUCTIONS FOR INSTALLATION AND CONNECTION OF ELECTRIC
FENCES FOR ANIMALS.
The following safety information is part of the Australia/New Zealand standard AS/NZS
60335.2.76:2003 amendment 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 hazard 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 energizers or from independent fence cir-
cuits of the same energiser.
>For any two separate electric fences that are each supplied from a separate independently timed
energiser, the distance between the wires of the two fences must be at least 2.5 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 razor wire must not be electrified by an energiser.
>A non-electrified fence incorporating barbed or razor 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
constructed so as to ensure that these wires are positioned at a minimum distance of 150mm from the
vertical plane of the non-electrified wires. The barb or razor 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 energiser’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.
Important: 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 Clearance (metres)
Up to 1,000 3
1,000 V - 33,000 4
Greater than 33,000 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 projec-
tion 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 energizer 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 size of the warning sign must be at least 100mm x 200mm. The background color 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 equiva-
lent to that provided by the fence energiser.
>This energiser must be installed in accordance with the
standard AS/NZS 3014:2003.
