Connecting leads shall not be installed in the same conduit as the
mains supply wiring, communication cables or data cables.
Connecting leads and electric animal fence wires shall not cross above
overhead power or communication lines.
Crossings with overhead power lines shall be avoided wherever
possible. If such a crossing cannot be avoided it shall be made
underneath the power line and as nearly as possible at right angles to
it.
If connecting leads and electric animal fence wires are installed near an
overhead power line, the clearances shall not be less than those shown
in the table below.
Minimum clearances from power lines for electric animal fences
Power line voltage
≤1000 V
>1000 V to ≤33,000 V
>33,000 V
If connecting leads and electric animal fence wires are installed near an
overhead power line, their height above the ground shall not exceed
3 m (10'). This height applies to either side of the orthogonal projection
of the outermost conductors of the power line on the ground surface,
for a distance of:
2 m (6'6") for power lines operating at a nominal voltage not
•
exceeding 1000 V.
15 m (50') for power lines operating at a nominal voltage
•
exceeding 1000 V.
Electric animal fences intended for deterring birds, household pet
containment or training animals such as cows need only be supplied
from low output energizers to obtain satisfactory and safe performance.
In electric animal fences intended for deterring birds from roosting on
buildings, no electric fence wire shall be connected to the energizer
earth electrode. A warning sign shall be fitted to every point where
persons may gain ready access to the conductors.
Where an electric animal fence crosses a public pathway, a non-
electrified gate shall be incorporated in the electric animal fence at that
point or a crossing by means of stiles shall be provided. At any such
crossing, the adjacent electrified wires shall carry warning signs.
Any part of an electric animal fence that is installed along a public road
or pathway shall be identified at frequent intervals by warning signs
securely fastened to the fence posts or firmly clamped to the fence
wires.
The size of the warning sign shall be at least 100x200 mm (4x8").
•
The background colour of both sides of the warning sign shall be
•
yellow. The inscription on the sign shall be black and shall be
either:
or the substance of "CAUTION: Electric fence".
The inscription shall be indelible, inscribed on both sides of the
•
warning sign and have a height of at least 25 mm (1").
Ensure that all mains-operated, ancillary equipment connected to the
electric animal fence circuit provides a degree of isolation between the
fence circuit and the supply mains equivalent to that provided by the
energizer.
Protection from the weather shall be provided for the ancillary
equipment unless this equipment is certified by the manufacturer as
being suitable for use outdoors, and is of a type with a minimum
degree of protection IPX4.

Frequently asked
questions/Troubleshooting
What voltage is required to control animals?
4 kV is widely accepted as the recommended minimum voltage to
control animals. However, you also require a well constructed fence
system to ensure that animals cannot push through electrified wires.
The fence voltage is below 4 kV. How do I increase the voltage?
Check the energizer.
Ensure that the energizer is on and set to operate
at full power. Disconnect the fence wire from the energizer's fence
output terminal. Measure the voltage across the energizer terminals
using a Fault Finder, Digital Voltmeter or a remote control handset. If
the voltage is less than 6 kV, the energizer may require servicing.
Check the energizer earthing.
Use the procedure described in
and testing an earth system
on page 6.
Check your fence system for faults.
voltage is faults on the fence line.
If the fence, earth and energizer are in good condition and the voltage
is still below 4 kV, talk to your nearest reseller. Recent extensions to
your fence, a poor fence layout, or soil conditions may be causing
inadequate voltage.
How do I locate faults?
The recommended tool for locating faults is a Fault Finder or remote
control handset. These have a combined voltage and current meter
which allows you to rapidly locate sources of current leakage.
Alternatively, use a Digital Voltmeter. Use cut-out switches to turn off
the power to different sections of the farm. If the voltage on the fence
increases when a section of the farm is turned off, then investigate that
section for possible faults.
There are no lights flashing on the energizer.
Ensure the power supply is on. Check the fence system for faults (see
above). Check the energizer (see above). If the energizer still does not
operate, it may require servicing.
The energizer does not respond to commands from the Remote
Control Handset.
Ensure that the remote contact on the Remote Control Handset is
•
in contact with the fence wire before pressing
(Holding the button down for an extended period will not make
the remote control work better.) After pressing
for two seconds for the ON or OFF message to disappear from the
display, as the energizer may send out a final pulse after receiving
the signal to deactivate. Similarly, allow two seconds for the
energizer to send out its first pulse after receiving the command to
reactivate.
If the symbol is displayed on the Remote Control Handset,
•
replace the 9 V alkaline battery and try again.
Rusty or oxidised wire can hamper the quality of the signal you
•
receive. To obtain a clear signal, rub the Remote contact against
the fence wire to break through the layer of rust or oxidation.
Ensure that no spring gates or cut-out switches have been left
•
open. Sometimes the remote control will work in spite of minor
breaks in the wire, although reliable operation under such
conditions is not guaranteed.
Check for spark gaps and loose wire joints in the fence. Severe or
•
multiple spark gaps reduce the effectiveness of the remote control.
Use the fault finding function to locate faults in the fence line. See
•
Using the fault finder
on page 3.
Check all connections to the fence and the earth system. Ensure
•
that the energizer is connected to the power supply and the fence
system and that the energizer is switched on.
