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

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 (except solar devices) 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.
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!
