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 the required number of 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. The table below specifies the
minimum number of 2 m (6'6") earth rods
recommended for an earthing system:
Energizer
0.5 J model
Test the earth system, using the following
procedure:
1 Turn off the energizer.
2 At least 100 m (330') away from the
energizer, short circuit the fence by laying
several steel rods or lengths of pipe
against the fence. In dry or sandy
conditions, it may be necessary to drive
the rods up to 300 mm (12") into the
earth.
Note:
It is not acceptable to short-circuit
a fence return system to the earth wire of
the fence.
3 Turn the energizer back on.
4 Using an electric fence voltmeter, ensure
that the fence voltage is below 2 kV.
Check your earth system.
5
voltmeter's earth probe into the ground at
the full extent of the lead, and clip the
other lead to the last earth rod. The
voltmeter should not read more than
0.8 kV. Anything higher than this indicates
that better earthing is required. Either add
more earth rods or find a better ground
area to drive in the earth rods.
Note:
When earthing energizers located in
dairies, earth at least 20 m (65') away from the
dairy using double-insulated lead-out wire to
avoid touching the dairy building or equipment.
