Introducon
Welcome to the shocking world of JVA electric fencing and thank you for placing your
faith in our product range. In doing so you have joined the worldwide body of sasfied
JVA users who are benefing from our products. Please note: This booklet is an
abridged version of the full JVA Electric Fence Installaon and User Manual which can
be found on our web domain and is intended just to assist you to www.jva-fence.com,
install your unit. For full informaon on your unit please consult our website.
Before commencing with your installaon please also note that an electric fence is a
psychological fear barrier that works on the principle of giving an animal a very short
duraon, powerful, yet safe shock that will discourage the animal from making contact
with the fence again. It is therefore important that an animal gets a good shock the
first me it makes contact with the fence. So, do not rush animals at the fence and
make sure the fence is operang at full capacity when introducing new animals to
electric fences.
Installaon Instrucons
For SV2, SV5, SV10 Integrated Solar Energizers and RSG1 Baery Unit
1. Opening up and geng ready
ØOn opening the box and removing your solar energizer, make sure that your solar
panel is plugged into the energizer. The internal baery will have already been
connected at the factory. (Only applicable to solar powered energizers.)
ØCheck that you have a mounng bracket in the box.
ØHave your mounng post ready. This can be a wooden pole or metal standard.
ØThe unit needs to be le in full, direct sunlight for a day to ensure that the
baeries are fully charged before use.
2. Posioning the energizer
ØIf the unit is to be used on a permanent electric fence layout, try to posion the
unit as centrally as possible. This will reduce the load on the unit.
ØIf the unit is to be used for strip grazing, it is generally placed at the end of the
line where the poliwire reels are located.
ØSolar energizers must be placed in direct sunlight facing towards the equator.
(North in the southern hemisphere and south in the northern hemisphere).
ØKeep solar panels clean. 1

3. Basic Electric Fence Circuits
It is important to understand the basic circuits applicable to electric fencing. An
electric fence comprises three components: the energizer, the earthing system and
the fence itself. Connect the three together and you have your basic circuit. An animal
touching the fence closes this circuit which allows the electricity to flow through the
circuit and thus shock the animal.
Basic Circuit for Moist Condions
The Earthing System: DOs and DON’Ts of Earthing
Basic Circuit for Dry Land Condions
Parallel vs Series Wired Circuits
The circuit is closed between
the live wire and the ground
when the animal makes
contact with live wires.
The circuit relies on good
current flow through the
moist ground.
Earth Stakes
The animal closes
the circuit between
the live and earth
return wire.
Earth Stakes
Dry Ground
Moist Ground
Moist ground is a good conductor of electricity, so in this circuit the electricity
will flow from the Energizer, along the wire, through the animal closing the
circuit, back through the ground to earth electrodes and on up into the
energizer, thereby compleng the circuit and delivering the shock.
Parallel wiring reduces the resistance of the fence line, thereby enabling it to
deliver a more powerful shock but it is less sensive to shorng. This makes it
more suitable for livestock control but less suitable for security fences.
DO
ØInsert at least three 1,2m long earth stakes at the energizer
ØPlace the earth stakes 1,2m apart
ØConnect the earth stakes together by using a single length of
underground cable
ØKeep earth stakes at least 2m away from any mains power
ØIn an urban area, install addional earth stakes every 30m
ØIn rural areas, install addional earth stakes every 100m
We cannot stress enough the importance of good earthing. A poor earth system will greatly reduce the effecveness of your electric fence. For strip grazing
fences on irrigated pastures a galvanized earth stake at the energizer should suffice. For permanent electric fences see below.
Dry ground is a poor conductor of electricity. In this circuit one adds an earth
return wire (B) to the fence. The animal now closes the circuit between the
live wire (A) and earth return wire (B) and so one does not rely on the poorly
conducve, dry ground to close the circuit.
Series wiring results in one long wire, thereby increasing the resistance of the
fence. This circuit is generally used for security fencing. Short out any wire and
the monitor will trigger an alarm.
DON’T
ØConnect more than one energizer to an earth stake
ØConnect your energizer earth to ESKOM or TELKOM’s earth stakes
ØAllow the earth system to touch any part of a building
ØConnect the earthing system to water pipes
ØInsert earth stakes where they can be tripped over
ØUse unlike metals e.g copper to galvanized, as this will cause electrolysis

1. Power Buon
ØIf the energizer is off, push the power buon to turn on
ØIf the beeper is giving an audible warning, push the buon to silence the
beeper for 10 minutes.
ØIf the energizer is on, push the buon to switch off.
2. Status Red LED – This LED has mulple funcons:
ØSlow flash (once per pulse) – fence overload
ØFlashes twice (two per pulse) – Baery low
ØFlashes an error code if internal error causes the energizer to shut down.
3. Energizer O.K. Green LED – Flashes with each pulse to show the energizer is
operang correctly.
4. Kilovolts Display – Shows the voltage on the output terminals. The higher the
voltage the more effecve the fence.
5. Joules Display – Shows how much energy the energizer is storing for each
fence pulse.
6. Power Supply Voltage – When the energizer is switched off, it will display the
power supply voltage. This is useful for quickly checking what the baery
voltage is.
Lightning
All JVA energizers are fied with surge protecon to protect them from lightning.
However, nature is extremely powerful so, we strongly recommend that lightning
diverters be installed on a permanent electric fence line. Regreably even these will
not protect the unit from a direct strike. (See installaon instrucons that come with a
JVA lightning diverter or www.jva-fence.com/videos/jvalightningdiverter.)

Warranes
The warranes on JVA products are product related and range from three months to
ten years. For example, porcelain and GFT insulators are ten years whereas the
manufacturer's warranty on 7amp Hr baeries is only three months.
JVA energizers carry a two-year warranty against faulty workmanship or component
failure operang under normal condions. Acts of Nature such as lightning, flooding,
fire or damage caused by inappropriate usage, repairs conducted by non-JVA cerfied
technicians or malicious damage to the energizers will nullify the warranty.

1. Disconnect the energizer from the fence and check:
ØThe energizer – If it works, the fault is on the fence line.
ØIf not, check that the energizer is plugged in and the mains is on;
ØThat the baery is charged and the charger is working;
ØThat solar panels are clean and are charging.
If all these are correct then the energizer is faulty and may require repairing.
2. Reconnect the energizer and check the earthing system.
(See Earthing on web site)
3. Check the lightning diverter – may be blown.
4. Check the feed-out to the fence-line – may be damaged.
5. Using your cut-out switches and volt meter isolate the secon of fence
where the fault is located.
6. Walk this secon of fence to locate the fault. It could be:
ØBroken or twisted wire
ØExcessive compeon from vegetaon
ØA broken or cracked insulator
ØA tree branch fallen on the fence
ØA cut-out switch le open.
Fault finding is greatly facilitated by using a JVA Direconal Volt Meter.
Basic Fault Finding
If the voltage on the fence line drops below an acceptable level, follow these steps:
Law and Safety
The laws and safety regulaons vary from country to country and we recommend that
you check the regulaons applicable to your country. Below are some general
regulaons applicable to countries that have adopted the IEC 60335-2-76 standards.
ØEnsure that the energizer has a Cerficate of Compliance (COC)
ØAn electric fence must not be powered from two different energizers.
ØPlace the energizer out of the reach of children.
ØDo not electrify barbed or razor wire.
ØEnsure that the design of the fence cannot lead to entrapment.
ØWarning signs must be aached and prominently displayed, on the fence.
ØSome countries require barrier fences where the general public may inadvertently
Ø make contact with the fence. (Check local bylaws.)
ØAll joints must be securely clamped with line-clamps or solder.
ØLead-out, return and communicaon cables must not be in the same channelling.
ØFollow manufacturers’ recommendaons or local specificaons re: earthing.
ØOnly qualified or competent persons should operate the electric fence.
ØDo not remove the energizer casing with the mains power connected.
ØIf in doubt consult IEC 60335-2-76 or local bylaws concerning electric fencing.
