- Ensure that the appliance is installed at a safe distance from people and animals to avoid hazards.
- If connecting leads and electric fence wires are installed near an overhead power line, their height above the ground shall not exceed 3m. If connecting leads and electric fence wires are installed near a telecommunication line or a telecommunication cable, their distance to the line or the cable shall not exceed 2m.
- If you are using an electric fence to deter birds from roosting on buildings, do not connect the electric fence wire to the energizer earth electrode. Instead, fit a warning plate to every point where persons may gain ready access to the conductors.
- If you are using a non-electrified fence incorporating barbed wire or razor wire to support one or more off-set electrified wires of an electric fence, ensure that the supporting devices for the electrified wires are 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 should also be earthed at regular intervals.
- If the connecting cable of the device is damaged, do not attempt to repair it yourself. Contact the manufacturer or an authorized expert for assistance.
- Children are not allowed to play with the device.
- Do not climb on, over or through the fence. A gate or other type of passage must be used to pass through the fence.
- If contact with electrified fences cannot be avoided, especially with the head, neck or upper body, seek medical attention immediately.

Safety instructions
Please follow this instruction exactly and store it well when not in use. If the connecting cable of this device is damaged, the manufacturer, his after- sales service or a similarly qualified person must replace it in order to avoid hazard. Services and repairs only by authorized experts! Children are not allowed to play with the device!
Electric fences shall be installed and operated so that they cause no electrical hazard to persons, animals or their surroundings. This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance. (A2:06)
Contact with electrified fences must be avoided, especially with the head, neck or upper body. Do not climb on, over or through the fence. A gate or other type of passage must be used to pass through the fence.
Electric fence constructions, which are likely to lead to the entanglement of
animals or persons, shall be avoided. An electric fence shall not be supplied
from two (or more) different energizers or from independent fence circuits of
the same energizer. For any two (or more) different electric fences, each
supplied from a different energizer independently timed, the distance between
the wires of the two electric fences shall be at
least 2.5 m. If this gap is to be closed, this shall be effected by means of
electrically non-conductive material or an isolated metal barrier. An
energizer shall not electrify barbed wire or razor wire.
Any part of an electric fence which is installed along a public road or public
thoroughfare shall be identified at frequent intervals by warning plates
securely fastened to the fence
posts or firmly clamped to the fence wires. The background colour of both
sides of the warning plate shall be yellow. The inscription on both sides of
the warning plate shall be black and shall be the substance of TAKE CARE –
ELECTRIC FENCE or the symbol .
The size of the warning plates shall be at least 200 mm 100 mm. A distance of at least 10 m shall be maintained between the energizer earth electrode and any other earthing system such as the power supply system protective earth or the telecommunication system earth. Except for low output battery-operated energizers, the energizer earth electrode shall penetrate the ground to a depth of at least 1 m. Care shall be taken to avoid any damage to cables or pipelines.
Connecting leads that run inside buildings shall be effectively insulated from the earthed structural parts of the building. This may be achieved by using insulated high voltage cable. Connecting leads that run underground shall be run in a conduit of insulating material or else insulated high voltage cable shall be used. Care shall be taken to avoid animal or mechanical damage to the connecting leads.
Connecting leads shall not be installed in the same conduit as the mains supply wiring, communication cables or data cables. Connecting leads and electric 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 near as possible at right angles to it. If connecting leads and electric fence wires are installed near an overhead power line, the clearances shall be not less than those shown in below-mentioned table.
Power line voltage /Clearance
- ≤ 1.000 volts: 3 meter
- > 1.000 ≤ 33.000 volts: 4 meter
- > 33.000 volts: 8 meter
If connecting leads and electric 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
- 2 m for power lines operating at a nominal voltage not exceeding 1 000 V;
- 15 m for power lines operating at a nominal voltage exceeding 1 000 V.
If connecting leads and electric fence wires are installed near a
telecommunication line or a telecommunication cable, their distance to the
line or the cable shall not exceed 2 m.
Electric 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 fences intended for
deterring birds from roosting on buildings, no electric fence wire shall be
connected to the energizer earth electrode. A warning plate, as described
above, shall be fitted to every point where persons may gain ready access to
the conductors. 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 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 150 mm from the vertical plane of the non-electrified wires. The barbed wire and razor wire shall be earthed at regular intervals. Where an electric fence crosses a public pathway, a non-electrified gate shall be incorporated in the electric fence at that point or a crossing by means of a stile shall be provided. At any such crossing, the adjacent electrified wires shall carry warning plates as described above. Electric fence-appliances have to be driven in accordance with the position described in the instruction manual.
Install the energizer preferably in a location not exposed to direct sunlight and rain. All cables and wires for line and fence connection must be kept distant from any inflammable material. The mounting surface itself must consist of non-inflammable material. The installation of the electric fence- appliance has to be done onto inflammable floor. To avoid any lightning damages, the fence wire at the building has to be taken over an overvoltage protection equipment with a thrush and a spark plug gap which has to be mounted on incombustible material on the outside wall of the building. This has to be done before any connection to the electric fence-appliance. This applies also to combi devices, if these are powered by a mains adaptor.
Don’t connect to existing earth wires of the power supply-network. Any user of electric fence systems is legally indebted to control the fence appliance and the fence system regularly, in accordance with the conditions of use, at least once per day.
- visual check of the appliance and the fence system
- measurement of the minimum voltage of 2500V at each point of the fence
For using an electric fence-appliance in a barn, only specially constructed appliances may be used. Power surges triggered by thunderstorms can damage the insulation on electric fence devices. In such cases, mains voltage can get through to the electric fence and thereby seriously endanger humans and animals. In general we therefore recommend connecting mains-operated electronic fence devices only to a public power supply protected by a residual current circuit breaker with a maximum 30mA trip current. It is also sensible during thunderstorms to disconnect mains-operated electric fence devices from the electricity grid, and also, if possible, from the fence.
If no mains supply with circuit breaker protection is available, and if the device was connected to the fence system during a thunderstorm, it must be properly checked before being put back into service. That requires at least a mains connection with a residual current circuit breaker. For testing, the earthing connection on the device is connected to the protective earth of the mains supply grid, and then the power plug of the device is connected to the socket with residual current protection. If the device clocks correctly, and shows no deviation from normal behaviour, the device can again be connected to the fence. If however the circuit breaker trips again when the device is connected, the device must not be used any more, and must be repaired in a specialist workshop.
