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. 
Electric security fence 
– A fence used for security purposes 
which comprises an electric fence and a physical barrier 
electrically isolated from the electric fence. 
Physical barrier 
– A barrier not less than 1.5 m (5') high 
intended to prevent inadvertent contact with the pulsed 
conductors of the electric fence. Physical barriers are 
typically constructed from vertical sheeting, rigid vertical 
bars, rigid mesh, rods or chainwire mesh. 
Public access area 
– Any area where persons are 
protected from inadvertent contact with pulsed 
conductors by a physical barrier. 
Pulsed conductors 
– Conductors which are subjected to 
high voltage pulses by the energizer. 
Secure area 
– The side of an electric security fence where 
a person may come into contact with the electric fence, 
without the protection of a physical barrier. 
 
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 young children or 
by infirm persons without supervision. 
Young 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 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 barbed wire and razor wire shall 
be earthed at regular intervals. 
Follow our recommendations regarding earthing. See 
Installing and testing 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.
