Gallagher PowerPlus B40 Betriebsanleitung Seite 4

• Barbed wire or razor wire shall not be electrified by an energizer.
• A non-electrified fence incorporating barbed wire or razor wire may be used
to support one or more off-set electrified wires of an electric animal fence. The
supporting devices for the electrified wires shall be constructed so as to ensure
that these wires are positioned at a minimum distance of 150mm from the
vertical plane of the non-electrified wires. The barbed wire and razor wire shall
be earthed at regular intervals.
• Follow the energizer manufacturer's recommendations regarding earthing.
• Do not install an earth (ground) system for your electric fence within 10m (33ft)
of any power, telecommunications or other system.
• Except for low output battery operated energizers, the energizer earth
electrode should penetrate the ground to a depth of at least 1m (3ft).
• Use high voltage lead-out cable in buildings to effectively insulate from the
earthed structural parts of the building and where soil could corrode exposed
galvanised wire. Do not use household electrical cable.
• Connecting leads that are run underground shall be run in conduit of
insulating material or else insulated high voltage lead-out cable shall be used.
Care must be taken to avoid damage to the connecting leads due to the effects
of animal hooves or tractor wheels sinking into the ground.
• 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
Less than or equal to 1 000
Greater than 1 000 and less than or equal to 33 000
Greater than 33 000
• 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
This height applies either side of the orthogonal projection of the outermost
conductors of the power line on the ground surface, for a distance of
• m for power lines operating at a nominal voltage not exceeding 1 000V;
• 15m for power lines operating at a nominal voltage exceeding 1 000V.
• 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 (G600) shall be fitted to every point where persons
may gain ready access to the conductors.
