Gallagher BA20 Instrucciones página 6

• A non-electrifi ed fence incorpora ng barbed wire or razor wire may be used to support one or more off -set electrifi ed
wires of an electric animal fence. The suppor ng devices for the electrifi ed wires 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.
• Do not install an earth (ground) system for your electric fence within 10 m (33 ) of any power, telecommunica ons or
other system.
• Use high voltage lead-out cable in buildings to eff ec vely insulate from the earthed structural parts of the building and
where soil could corrode exposed galvanized wire. Do not use household electrical 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 below.
Minimum clearances from power lines for electric animal fences
Power line Voltage V
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 an earth stake. 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.
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.
