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 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 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 earthing arrangements.
Connecting lead– An electric conductor, used to connect
the energiser to the electric fence or the earth stake.
Electric 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 sur-
roundings. Electric fence con-structions that are likely to
lead to the entanglement of animals or persons shall
be avoided.
This energiser is not intended for use by young children
or infirm persons unless they have been adequately
supervised by a responsible person to ensure that they
can use the energiser safely. Young children should
be supervised to ensure that they do not play with the
energiser. An electric fence shall not be supplied from
two or more separate energisers.
22
For any two separate electric fences, each supplied from
a separate energiser independently timed, the distance
between the wires of the two electric fences shall be at
least 2 m (6'6"). 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
energiser.
A non-electrified fence incorporating barbed wire or
razor wire may be used to support one or more offset
electrified wires of an electric fence. The supporting de-
vices 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. For safety reasons
we recommend for offset fences only to use energisers
with a maximum of 5 joules output energy.
Follow our recommendations regarding earthing. See
"Installing and testing an earth system" on page 42.
A distance of at least 10 m (33') shall be maintained
between the energiser earth stake and any other earth-
ing 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 fence wires shall not cross
above overhead power or communication lines.
