Gallagher M1100 Notice D'installation page 6

Important Informa on
shall be constructed so as to ensure that these wires are posi oned at a minimum distance of 150
mm from the ver cal plane of the non-electrifi ed wires. The barbed wire and razor wire shall be
earthed at regular intervals.
• Follow the energizer manufacturer's recommenda ons regarding earthing.
• A distance of at least 10 m (33 ) shall be be maintaned between the energizer earth electrode and
any other earthing system connected pasrts such as the power suplly system protec ve earth or
telecommunica ons system earth.
• Connec ng leads that are run inside buildings shall be eff ec vely insulated from the earther
structural parts of the building. This may be achieved by using insulated high voltage cable.
• Connec ng leads that are run underground shall be run in conduit of insula ng material or else
insulated high voltage lead-out cable shall be used. Care must be taken to avoid damage to the
connec ng leads due 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.
• 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-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.
