Important Informa on
Minimum clearances from power lines for electric animal fences
Power line Voltage V Clearance m
Less than or equal to 1 000 3
Greater than 1 000 and less than or equal to 33 000 4
Greater than 33 000 8
• If connec ng leads and electric animal fence wires are installed near an overhead power line, their height
above the ground shall not exceed 3 m
This height applies either side of the orthogonal projec on of the outermost conductors of the power line
on the ground surface, for a distance of:-
-
2 m for power lines opera ng at a nominal voltage not exceeding 1 000 V;
-
15 m for power lines opera ng at a nominal voltage exceeding 1 000 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 sa sfactory and safe performance.
• In electric animal fences intended for deterring birds from roos ng on buildings, no electric fence wire
shall be connected to the energizer earth electrode. A warning sign shall be
fi ed to every point where
persons may gain ready access to the conductors.
• Fence wiring should be installed well away from any telephone or telegraph line or radio aerial.
• Where an electric animal fence crosses a public pathway, a non-electri fi ed gate shall be incorporated
in the electric animal fence at that point or a crossing by means of s les shall be provided. At any such
crossing, the adjacent electri
fi ed wires shall carry warning signs.
• Any part of an electric animal fence that is installed along a public road or pathway shall be iden fi ed by
electric fence warning signs (G6020) at regular intervals that are securely fastened to the fence posts or
fi rmly clamped to the fence wires.
• The size of the warning sign shall be at least 100mm x 200mm.
• The background colour of both sides of the warning sign shall
be yellow. The inscrip on on the sign shall be black and shall be
either:
-
the substance of “CAUTION: Electric Animal Fence” or,
-
the symbol shown:
• The inscrip on shall be indelible, inscribed on both sides of the
warning sign and have a height of at least 25mm.
• Ensure that all mains operated, ancillary equipment connected
to the electric animal fence circuit provides a degree of isola on
between the fence circuit and the supply mains equivalent to that
provided by the energizer.
• Protec on from the weather shall be provided for the ancillary equipment unless this equipment is
cer fi ed by the manufacturer as being suitable for use outdoors, and is of a type with a minimum degree
of protec on IPX4.
This energizer complies with interna onal safety regula ons and is manufactured to interna onal standards.

SERVICE OF DOUBLE-INSULATED APPLIANCES
In a double-insulated controller, two systems of insula on are provided instead of grounding. No equipment
grounding means is provided in the supply cord of a double-insulated controller, nor should a means for
equipment grounding be added to the controller. Servicing a double-insulated controller requires extreme care
and knowledge of the system, and should be done only by quali
fi ed service personnel. Replacement parts of a
double insulated controller must be iden cal to the parts they replace. A double insulated controller is marked
with the words “DOUBLE INSULATION” or “DOUBLE INSULATED”. The symbol for double insula on
may also
be marked on the appliance.
