circuits of the same energizer.

Avoid contacting electric fence wires especially with the head, neck or torso. Do not climb over, through
or under an electric fence. Use a gate or a specially designed crossing point.

For any two separate electric animal fences, each supplied from a separate energizer independently
timed, the distance between the wires of the two electric animal fences shall be at least 2,5 m. If this gap
is to be closed, this shall be effected by means of electrically nonconductive material or an isolated metal
barrier.

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 150 mm 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.

A distance of at least 10 m shall be maintained between the energizer earth electrode and any other
earthing system connected parts such as the power supply system protective earth or the
telecommunication system earth.

Connecting leads that are 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 are run underground shall be run in conduit of insulating material or else
insulated high voltage 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 Table 1.
Power line voltage, V
≤ 1 000
> 1 000 and ≤ 33 000
> 33 000
Table 1 – Minimum clearances from power lines for electric animal fences

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 to 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.
