than 0.5 kV. Anything higher than this indicates that better earthing is required. Either add
more earth stakes or find a better ground area to drive in the earth stakes. A voltage of
below 0.2 kV would be best.
Note:
When earthing energisers located in dairies, earth at least 20 m (65') away from the
dairy using double­insulated wire to avoid touching the dairy building or equipment.

Safety Considerations

Safety considerations according to European Security Standard EN 60335-2-76
Definition of special terms
Energiser – 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 conduc­
tors such as metal wires, stakes or rails.
Electric fence – A barrier which includes one or more electric conductors, insulated from earth,
to which electric pulses are applied by an energiser.
Fence circuit – All conductive parts or components within an energiser that are connected or
are intended to be connected, galvanically, to the output terminals.
Earth stake – Metal structure that is driven into the ground near an energiser and connected
electrically to the output earth terminal of the energiser, and that is independent of other eart­
hing arrangements.
Connecting lead – An electric conductor, used to connect the energiser to the electric fence or
the earth stake.
Electric animal fence – An electric fence used to contain animals within or exclude animals
from a particular area.
Pulsed conductors – Conductors which are subjected to high voltage pulses by the energiser.
Requirements for electric fences
Electric fences and their ancillary equipment shall be installed, operated and maintained in a
manner that minimises danger to persons, animals or their surroundings.
