Building an electric fence and an earth system
For a complete guide to building an electric fence and an earth system, visit the
website (see energizer packaging for details).
Note:
For this energizer, we recommend using at least nine 2 m (6'6") earth rods in
the earth system.
Bi-polar installation
In areas with poor earthing conditions, a 'bi-polar' installation may be used to
enhance the performance of the fence. With a bi-polar installation, all fence wires are
insulated. Alternate fence wires are interconnected to form one negatively charged
circuit and one positively charged circuit. The energizer passes half the output voltage
to the negatively charged wires and half the output voltage to the positively charged
wires. The animal gets a shock from touching a positive wire or a negative wire OR, if
touching both a positive and negative wire simultaneously it gets a stronger shock.
To construct a bi-polar fence:
1
Interconnect fence wires so that there are two different circuits, as shown in the
diagram.
2
Connect the Fence bi-polar terminal (yellow) to the earth system using insulated
cable.
3
Connect the Fence earth terminal (green) to the negative wires.
4
Connect the Fence output terminal (red) to the positive wires.
