How does an electric fence work?
An electric fence system comprises an energiser and an insulated fence. The energiser puts
very short pulses of electricity onto the fence line. These pulses have a high voltage, but are
of very short duration (less than 3/10,000ths of a second). However, a shock from an electric
fence pulse is very uncomfortable and animals quickly learn to respect electric fences. An
electric fence is not only a physical barrier, but is also a strong psychological barrier.
What are the benefits of an electric fence?
An electric fence has many benefits over conventional fencing:
• Requires less labour and material to construct than conventional fencing.
• Flexibility to change or add paddocks when required. The use of strip grazing techniques
can allow temporary fencing to be quickly and easily erected or removed.
• Controls a broader range of animals.
• Minimises damage to expensive livestock when compared with other fencing mechanisms,
for example barbed wire.
Installation
To set up the energiser for use, install the battery and connect the energiser to an electric fence
and an earthing system.
Installing the battery
1. Place the energiser on a flat surface.
2. Open the battery compartment by pressing
the latches firmly.
3. Connect the positive (red/black) lead to the
positive (+) terminal on the battery.
4. Connect the negative (black ) lead to the
negative () terminal on the battery.
5. Close the battery compartment
Positioning the energiser
Install the energiser:
• adjacent to the electric fence.
• preferably in the middle of the electric fence.
• where it will receive the most daily sun throughout the season.
• where a good earth can be obtained.
