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.
Electric fence constructions that are likely to lead to the entanglement of animals or persons
shall be avoided.
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 energiser 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 energiser by a person responsible for
their safety. 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 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 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 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 bar-
bed 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 58.
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.
