such crossing, the adjacent electrified wires shall carry warning signs.
Any part of an electric fence that is installed along a public road or pathway shall be identi-
fied at frequent intervals by warning signs securely fastened to the fence posts or firmly clam-
ped 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 inscripti-
on on the sign shall be black and shall be either like
the illustration to the right or the substance of
"CAUTION: Electric fence".
• The inscription shall be indelible, inscribed on both sides of the war-
ning sign and have a height of at least 25 mm (1").
Ensure that all mains-operated, ancillary equipment connected to the electric fence circuit
provides a degree of isolation between the fence circuit and the supply mains equivalent to
that provided by the energiser.
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 energiser. Ensure that the energiser is not set on half power. Disconnect the
energiser from the fence and earth system. Measure the voltage across the energiser terminals
with a PATURA fence compass, DVM or fence tester. If the voltage is less than 6 kV, request
your PATURA service agent to check the energiser.
Check the energiser earthing. Use the procedure described in "Installing and testing an earth
system" on page 37.
Check your fence system for faults. The most common source of low voltage is faults on the
fence line.
If the fence, earth and energiser are in good condition and the voltage is still below 4 kV, talk
to your PATURA distributor. They will help you identify whether recent extensions to your fence,
a poor fence layout, or soil conditions may be causing inadequate voltage.
