If you have to connect the energizer to a fence further away from energizer or you
need pull the cable under the driveway, please use Olli earth cable to connect the
fence to the device. Olli earth cable has a thick insulation that isolates the high
voltage that the fence energiser produces. You can use this cable to take the
fence wire through a wall and you can also install it under ground if this is
necessary.
Please never use any low voltage cables or ordinary electrical installation cables
as these can not to completely isolate the high voltage pulse that has a voltage of
up to 10 000 volts. Any leakages diminish the effect of the energiser and may
cause disturbances in telephones, TV-picture or radio.
5. Earthing
Earthing refers to fence earthing in use. When an animal touches the fence
conductor and the ground at the same time it completes the electric circuit and
suffers a shock. Therefore a proper earthing is necessary for the function of the
fence.
Earthing can be done either by using the ground as the electric earth or by using
a separate earth wire in the fence. In traditional earthing the animals gets a shock
when it touches the fence wire and the ground at the same time. In the two wire
system the animal gets a shock when it touches the electric wire and the ground
wire at the same time.
Earthing must be done even when a separate return wire is used. Never use
any fixed structures such as pipelines or buildings for earthing a fence
energiser.
6. Disturbances in electrical devices
The radio frequency of the pulse of a fence energiser is so low that a correctly
installed electric fence does not cause any visible or audible disturbances in radio
devices. The main reason for disturbances (typically a snapping noise in
loudspeakers) is an inadequate or incorrectly implemented earthing of the fence.
Check and fix the earthing of the fence according toe the chapter 4 in this guide.
The other typical reason for disturbances is sparking. A spark spreads a wire
spectrum electromagnetic radiation that can be heard as snapping in
loudspeakers of as horizontal disturbance stripes in TV picture.
Visible sparks on fence wires are signs of poor connections. They cause
disturbances and add resistance to the fence thus reducing its effect. Always use
proper connectors when connecting the energiser to the fence or connecting
wires to each other.
7. Starting and using the energizer
When the energizer is connected to both power source and fence according to all
instructions, you may start the energizer. There are two different power ranges in
