Important Informa on
to the eff ects of animal hooves or tractor wheels sinking into the ground.
• Connec ng leads shall not be installed in the same conduit as the mains supply wiring, communica on
cables or data cables.
• Connec ng leads and electric animal fence wires shall not cross above overhead power or communica on
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 connec ng 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 following.
Minimum clearances from power lines for electric animal fences
Less than or equal to 1 000
Greater than 1 000 and less than or equal to 33 000
Greater than 33 000
• 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.
• Where an electric animal fence crosses a public pathway, a non-electrifi 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 electrifi 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 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.
WARNING: Risk of Electric Shock. Do not connect the energizer simultaneously to a fence and to any
other device such as a ca le trainer or a poultry trainer. Otherwise, lightning striking your fence will
be conducted to all other devices.
This energizer complies with interna onal safety regula ons and is manufactured to interna onal
standards. Gallagher reserves the right to make changes without no ce to any product specifi ca on to
improve reliability, func on or design. E & OE.
