
Inspect the battery regularly to ensure that the
electrolyte level does not fall below the surface of the
battery plates.

Top up the battery using distilled water. Do not
overfill. Refer to the battery manufacturer's
recommendations for more information.
Battery safety

Ensure that the battery is well ventilated when
recharging.

Avoid temperatures greater than 50 °C (120 °F).

Ensure that the battery is not exposed to a naked
flame or sparks.

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.
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 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 energizer by a person responsible for their safety.
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 off-set 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.
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.
