Reducing the fence voltage output
In some areas, it may desirable to have a reduced fence voltage output,
for example where there is a risk of fire or where there is a chance that
people might come into contact with the electric fence (e.g. around a
house or next to a public roadway).
To reduce the fence voltage, use the Fence half voltage terminal
(yellow) instead of the Fence full voltage terminal to connect the
energizer to the fence. See the
Installation section
on page 3.
When the Fence half voltage terminal (yellow) is used, the fence voltage
will not exceed 5 kV, however the output power remains the same.
Fence designs
Fences can be constructed to suit the type of livestock and materials
available. Discuss with your reseller which design best suits your needs.
Some suggested fence configurations are below.
Cattle and horses
10-15 m (33-49’) spacing, posts only
15-20 m (49-65’) spacing with droppers
Sheep, goats, cattle and horses
10 m (33’) spacing, posts only
15 m (49’) spacing with droppers
Wild animals
7 wire, 10 m (33’) spacing with droppers
End assemblies
Angle stay
Suitable for field gate, high-tension strainer.
After firmly setting the footed strainer in the ground, dig in the stay
block just below ground level, at a distance to ensure the angle stay will
be held snugly in position. The stay can be levered into position with a
spade.
All-live system
Fence-return system
Horizontal stay
Suitable for field gate, high-tension strainer.
Very simple to erect and most suitable as a high tension strainer,
excellent in areas where the soil gets very wet or where heavy frost
occurs.
Installing and testing an earth system
Select a suitable site for the earth system. Sites need to be:
•
At least 10 m (33’) from other earth systems (e.g. telephone,
mains power or the earth system of another energizer).
•
Away from stock or other traffic that could interfere with the
installation.
•
At a site that can be easily observed for maintenance.
•
Ideally at a site that has damp soil (e.g. a shaded or swampy
location). Note that the earth does not need to be directly
adjacent to the energizer installation.
Drive four 2 m (6’6”) earth rods into the ground. Use high-voltage,
insulated cable and earth clamps to continuously connect the earth rods
and the energizer’s Fence earth terminal. Make sure the insulation is
stripped back to ensure good contact between the wire and the earth
rod.
Test the earth system, using the following procedure:
1
Turn off the energizer.
