How many lines to build?
At what height?
General idea of the electric fence
This is how an electric fence works under normal conditions
Principles of an electric fence Farmcomp Oy
The animal touches the fence and the ground at the same time
= gets a light electric shock.
Principles of an Electric Fence Farmcomp Oy
Electric fence energiser produces the high voltage impulses every second and sends them to wires /
tapes / ropes. When an animal touches the fence, electricity goes through the body of an animal to the
ground. The animal gets a light electrical shock and goes away from the fence. The electric shock is not
dangerous for an animal but teaches the animal not to approach the fence any more.
Power suply options of an electric fence energiser:
Mains 220 V Battery 9 V or Rechargeable battery 12 V Solar panel
Basic rules on choosing a suitable model of an electric fence energiser.
If possible always choose a mains supply energiser – Cheaper to use
Use a powerful energiser when:
- Fencing animals with long or thick fur
- The first strand of a fence is too low
(risk: grass/bushes might touch the
fence which would cause the
electricity to leak)
- Building a long fence
- There are male animals in the herd

Basic models:
Measuring and marking the territory Installing posts for building gates:
1. Make a decision on how long a fence you want, where and
how many gates you want, then where the energiser will be.
2. Install posts for the gates. A gate should allow animals,
humans and machines to easily pass in and out of the gate.
3. Install posts for the whole length of the fence (on the whole
perimeter of the fence).
4.4. The height of the posts should be the same on the whole
length of the fence (relative to the terrain). The distance
between posts should be determined according to the terrain.
The more height differences, uneven surface , ditches there are
on the land, the shorter the distance between the posts.
Maximum distance between the posts: 8 meters.
5. The Corner Posts need to be strengthened to support the
stress put on them by the ropes and tapes.
Size of the gate
Size of the gate may vary between 2,5 m an d4,5 m.
Spring gate: 4,5 m
Rope gate: 3,2 or 4,5 m.
When you build a gate using only gate handles and gate
insulators, distance between the posts in the gate should be
from 2,5 to 3,5 m.
Spring Gate Rope Gate
Building the spring gate
Assembling the gate:
1. OLLI-spring gate consists of a spring, isolated
gate handle and gate insulators. Isolated gate
handles allow you to open and close the gate
without switching off the fence energiser.
2. Determine the appropriate height of the lines in
the fence. Height and quantity of lines in the
fence is determined according to the specific
recomendations for different kinds of animals.
Order of the assembling:
1. Install posts for the gate
2. Screw gate insulators into the posts
3. Attach the gate handle to the spring
4. Attach the spring gate to the gate insulators
1,2- ~ 2,5 m
3,2-3,5 m

Gate closed
Installing the insulators
Installing the insulators
in the electric fence:
1. Place the posts to the whole length of the
fence.
2. Determine the height of the lines.
3. Height of the lines is determined according to
the specific recomendations for each kind of
animal.
4. Screw the insulators to the posts using a
special tool.
5. Check that all the insulators are installed with
the place for the wire upwards.
Important! When using wooden
posts it is necessary to use the
insulators because wet wood causes
the electricity to leak out of the fence.
Wires and Tapes should not touch the
uninsulated elements of the fence.
This can cause serious damage to
the energiser.
Installing Tapes or Wires
Installing tapes or wires:
1. Attach a wire to a gate insulator using a special
connector, Make several turns over the gate
insulator hook so that the wire is tightly attached
to the insulator.
2. Tighten the connector to ensure good electrical
contact.
3.Connect lines of the fence with each other.
Make connections between the lines each 200-
300 meters to ensure electricity flow in the whole
length of the fence.
4. Check the connections.
Building the fence
Connect lines of the
fence to each other
Continue building the lines
under the gate with the OLLI-
undergate cable. This will
ensure good electricity flow
under the gate.
Wire / Rope fence
Installing the connectors
Connecting wires
To ensure good electrical connection, use
special OLLI-connectors. Usual connectors
easily rust and stop electricity flow in the
fence.
Order of assembling:
1. Place the wire to the connector
2. Tighten the connector to ensure good
electrical contact
Choose high quality wires
and connectors
Important! Don’t connect the wires with a knot! Knots do not
ensure good contact and as a result cause sparking.
Sparking heats the wires and cause damage to it. Sparking
can also cause interferences to radio and TV frequences.
Don’t do this!!! Any vegetation – Grass, Bushes, Trees, or wood and metal directly
on the fence wires will cause the fence to leak electricity.
It reduces the power going through the fence, when it has been
raining the electricity can also ”jump” (Sparking) to a post if the
insulator is broken or poor quality.
We recommend checking the fence every week or after a storm.
←The high quality Olli connector
- Stainless Steel
- Allows connection to be tight
- Crosses all wires
Installing tensioners
Tensioning wires
Tensioners are used to tighten the
whole length of the fence. When wires
are well tightened, it keeps them more
protected from winds and allows a
longer life of a wire.
Order of installation:
1. Put a wire to the tensioner
2. Tighten the wire until it’s straight and
tight.
3. Tie off the rope.
Installing the energiser
Installing the energiser:
1. Attach the energiser to the post with the screws
included in the delivery
2. Place the Olli earth stake near the energiser. 80 cm of the
earth stake should be put into the ground. For dry/sandy
ground use several earth stakes.
Order of installing:
1. Attach the energiser to the post
2. Put the earth stake 80 cm to the ground.
3. Connect the energiser to the power supply.
IMPORTANT:
Use only OLLI-zinc covered earth stakes. Low-quality earth
stakes rust easily and stop the normal functioning of the
fence. You will need 1-3 earthing stakes depending on how
powerful energiser you choose, how long fence you are
building and how dry the ground is nearby. Place the earth
stakes at the distance of 1 m away from each other.
Earthing of an energiser should not be connected to the
earthing of buildings, general earthing or water pipe.
According the safety instructions, electric fence energiser
should be earthed a safe distance (at least 10 m) away
from the earthing of buildings (or water pipes).
That’s why it is highly recommended to use OLLI-undergate
cable for making good earthing, It is most important when the
energiser is situated in the building and the earthing should be
made out of the building.
If the earthing of an energiser is connected to the water pipe,
it can cause light electrical shock e.g. in the shower. If
connected to the earth of a building or general earthing of the
electric network, it can cause interferences in the functioning
of electrical and radio devices e.g. phone,
The best place for the earthing stake
is near any water (for example near
the swamp, lake or river).
Never put an earthing stake under the
roof or under the buildings because
dry ground is a very poor electrical
conductor!
Make Sure the earthing is good !
Connecting the energiser
Connecting the energiser:
1. Install lightining protector, it prevents damage
to an energiser if it is struck by lightning.
Connect the lightning protector to the fence.
2. Connect the energiser to the earth stake and to
the lightning protector.
3. Connect the energiser to the power supply.
Note;
”+” = Positive
”-” = Negative/Earth
Order of connecting:
1. Install lightning protector.
2. Connect lightning protector to
the fence,
3. Connect the energiser to the
earthing stake and to the
lightning protector.
4. Connect the energiser to the
power supply.
Optional lightning protector
installation
Testing the fence
Measuring voltage in the fence:
Switch the energiser on and check the voltage
on wires and connectors using the tester.
There shouldn’t be sparkling in any part of the
fence. If you can hear clicks at the places of
connection, this is a sign of a bad connection
and sparkling. Sparkling warms the wires and
causes serious damages to the fence.
Order of testing:
1.Earth the tester
2.Check the voltage at the
places of connections.
3.Check voltage on the
wires.
Minimum voltage in fence
should be 4,0 kV (4000V)
depending on the model of
the energiser.
Testing the energiser
Test your energiser with Olli Digitester or
Supertester
Disconnect the energiser from the fence and check
the voltage between the buttons of the energiser
Switch the energiser on and touch the earth button
(Black) of the energiser marked with the earth
probe on the tester.
With the tester touch the Positive button (Red)
marked with the pin on the tester.
Depending on the energiser the tester
should show voltage 4000-10 000 V
(Digitester: 1 kV = 1000 V).

There are 3 levels of checking – Happy – Be Careful – Sad
• Happy – Do Nothing
• Be careful - Check the fence there is a power loss
• Sad - There is a real problem
A normal electric fence in winter
ATTENTION ! Snow/Ice insulates the ground and does not allow the electricity to go
to the earth stake, so the animal does not get a shock !
No Shock !
There are 2 options to build a winter fence:
1. “Double contact” fence • Two lines one positive one negative
• Problem is to stop them touching each other
• Not recommended
2. Fence using winter tape or a “thick board” 100 mm tape • Recommended
