Electric fence constructions 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 animal fence shall not be supplied from two or more separate energisers.
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 nonconductive material
or an isolated metal barrier.
Barbed wire or razor wire shall not be electrified by an energiser.
A nonelectrified fence incorporating barbed wire or razor wire may be used to support one
or more offset electrified wires of an electric animal fence. The supporting devices for the elec
trified 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 nonelectrified wires. The barbed wire
and razor wire shall be earthed at regular intervals. For safety reasons we recommend on off
set 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 53.
A distance of at least 10 m (33') shall be maintained between the energiser earth stake 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, com
munication cables or data cables.
Connecting leads and electric fence wires shall not cross above overhead power or communi
cation 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 fence wires are installed near an overhead power line, the
clearances shall not be less than those shown in the table below.
