6.2 Connecting the fence energiser to the fence
Connect the fence energiser to the fence using the fence connector wire supplied
with it. Attach the fence connector wire’s connector to the fence wire or fence tape,
tightening the screws properly to ensure good electrical connection.
Connect the stripped end of the wire to the fence energiser’s red fence terminal
marked with the lightning symbol: Depress the connector button when pushing
the wire into the connector’s receptacle (a). Do not force the wire in. Release the button
and make sure the connection is secure by gently pulling on the wire. Connect the
earthing wire in a similar manner to the black earth terminal (b) marked with the earthing symbol:
If the fence is located far from the fence energiser, use Olli high voltage cable for connecting the energiser to the
fence. If necessary, the high voltage cable can be buried underground or used when passing through walls.
Do not
use ordinary electrical installation cable, for its insulation is not adequate for electric fence use, in which
voltage can exceed 10,000 volts.
6.3 Earthing
Earthing is essential for the electric fence to work, as the electricity returning to theenergiser through soil makes up
one-half of the energiser impulse circuit.
Inadequate earthing is the most common cause of poor fence operation (and of interference with radio equipment).
Inadequate earthing is commonly caused by dry soil, insufficient burying depth of earthing rods, insufficient number
of earthing rods, or wrong earthing rod material (e.g. rebars which, when rusted, conduct electricity poorly). Fixing
earthing by following these instructions will often eliminate many problems related to weak fence impulses.
6.3.1 Earthing rods
Adequate earthing of the fence energiser requires a sufficient number of earthing rods. Depending on the length
of the fence and the power of the energiser, 1–6 earthing rods are usually needed. At least 1 to 3 earthing rods are
recommended for Olli 450B+. In dry conditions and in case of long fences, even more earthing rods may be required.
There cannot be too many earthing rods; it is better to have some extra than too few.
Bury the earthing rods
completely underground, at a distance of at least 1 m from each other. The best place for an earthing rod is moist soil
or clay – for example, a ditch bank. If the soil is quite dry, regular watering of the earthing location improves earthing.
The current in the electric fence flows from the energiser to the fence wires and from the fence through the soil to
6. Fence energiser installation
6.1 Wall or post mounting
Fix the device to a reliable surface or post by screws. Mount it in a vertical position, so that the fence connectors are
at the bottom edge of the device. Protection against splashing water is effective only if installed in the vertical posi-
tion. Do not install the device upside down. Do not overtighten the mounting screws. Do not submerge the device
in water or leave it lying on the ground. The warranty does not cover moisture damage resulting from improper
installation.
