ground at the full extent of the lead, and clip the other lead to the
last earth rod. The voltmeter should not read more than 0.8 kV.
Anything higher than this indicates that better earthing is required.
Either add more earth rods or find a better ground area to drive in
the earth rods.
Note:
When earthing energizers located in dairies, earth at least 20 m
(65') away from the dairy using double-insulated lead-out wire to avoid
touching the dairy building or equipment.
Temporary electric fencing
A temporary fence can be quickly erected and easily moved allowing the
farmer to:
Make smaller paddocks (fields)

 Keep herds of animals separated
 Ration feed
Note:
Use more wires for smaller animals and wild animals. Politape
should be used when greater visibility is required (e.g. horses).
An example of a temporary fence is shown below.

Safety considerations

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.
Insert the voltmeter's earth probe into the 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. See
an earth system on page 8.
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.
