2 IMPORTANT NOTES
2.1 ELECTRIC FENCES
1. Electric fences are not toys; do not let children play with them.
2. Electric fences should only be installed with regard to the relevant
standards and work place health and safety requirements.
3. Electric fences must have an ‘earth’. An electric fence earth or ground
is one or more pieces of metal (e.g. earth rods) driven into the earth.
2.2 ENERGIZERS
1. The energizer places a very fast, very high voltage pulse on the fence
live wires approximately once every second. The fence is ‘safe’ in that
the pulse is too short to cause electrocution. Please be advised that
there is always a risk associated with any device designed to impart an
electric shock. Do not allow children or elderly persons to touch the
energizer or fence live wires.
2. The maximum length of fence able to be energized depends on many
factors, for example the earth resistance, number and spacing of wires
on the fence, type/quality of insulators, resistance of wire etc. The
amount of grass or bushes touching the wires also alters the perfor -
mance. Fence circuit layout is very important. Another factor to con -
sider is acceptable fence voltage, for some stock situations this is 3kV,
others may require more, or less. Therefore the rated kilometres (dis -
tance) of fence that the energizer will power effectively is a guide only.
2.3 POWER SUPPLY OPTIONS
1. The JMB electric fence energizers can be powered from a number of
power sources.
a. 12V external rechargeable battery (not supplied)
b. 12V external battery with solar panel (not supplied)
