• WARNING: Read all instructions.
• Electric fences should be installed and operated so that
they cause no electrical hazard to persons, animals or their
surroundings.
• Electric fence constructions which are likely to lead to the
entanglement of animals or persons should be avoided.
• In areas of public access, use an electric fence warning sign
(G6020) every 10m (33ft) to identify the electrifi ed wire(s).
• Check your local ordinance for specifi c regulations.
• Crossing with overhead powerlines should be avoided
wherever possible. If such a crossing cannot be avoid ed, it
should be made underneath the powerline and as nearly as
possible to right angles.
• If connecting leads and electric fence wires are in stalled near
an overhead power line, the clearances should be not less than
those shown below:
• If connecting leads and electric fence wires are in stalled near
an overhead power line, their height above the ground should
not exceed 2m.
• This height applies either side of the orthogonal pro jection
of the outermost conductors of the power line on the ground
surface, for a distance of:
• 2m for power lines operating at a nominal voltage not
exceeding 1 000 V;
• 15m for power lines operating at a nominal voltage
exceeding 1 000 V.
• Fence wiring should be installed well away from any
telephone or telegraph line or radio aerial.
• An electric fence should not be supplied from two different
energizers or from independent fence circuits of the same
energizer.
• For any two different electric fences, each supplied from
a different energizer independently timed, the distance
between the wires of the two electric fences should be at least
2m. If this gap is to be closed, this should be effected by means
of electrically non-conductive material or an isolated metal
barrier.
• Do not electrify barbed or razor wire in an electric fence.
