1 Important notes –PLEASE READ
1.1 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 should be signed. Warning signs that comply to IEC
standards should be prominently displayed on electric fences at
distances specified by the country in which they are installed.
4. Electric fences must have an ‘earth’. An electric fence ground is one
or more pieces of metal (eg. 1.8m Galvanized earth rods) driven into
the earth to a depth of at least 1.2m. Three earthing rods are
recommended for customers purchasing the MB8, MB12, or MB16.
Additional earth connections may be required at the energizer or
along the fence in poor soil conditions.
1.2 Energizers
1. The energizer places a very short, safe, high voltage pulse on the
fence live wires approximately once every second. 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 energised depends on many
factors, for example the earth resistance, number and spacing of
wires on the fence, type/quality of insulators, resistance of wire,
whether the wiring configuration is series or parallel etc. The amount
of grass or shrubbery touching the wires also alters the performance.
Fence circuit layout is very important. Another factor to consider is
acceptable fence voltage, for some stock situations this is 3kV others
require more or less. Therefore the rated mileage of fence that the
energizer will power effectively is a guide only.
3. DANGER! The Energizer should never be operated with the cover
removed as high voltages exist inside the enclosure while operating.
High voltage may remain on some internal parts long after the unit has
been switched off.
1.3 Power Supply Options
The JVA MB series of electric fence energizers can be powered from a
range of power sources.
•12 or 24V external battery (not supplied)
•12 or 24V external battery with solar panel (not supplied)
•110/240Vac via power pack (supplied with MB models only)
The JVA SV series of electric fence energizers are fully self contained
solar powered energizers. Each energizer in the SV series comes with an
internal battery, integrated battery charger, solar panel bracket and solar
panel.

1.3.1 IMPORTANT NOTES
•Always ensure adequate ventilation is given to the external 12 volt
battery. Lead Acid batteries may emit explosive gases while
charging!
•Always mount the power supply either indoors or undercover.
1.4 Auto-SyncTM
Auto-SyncTM is a new method of synchronising electric fence energizers
patented by Pakton Developments Pty Ltd.
Auto-sync detects when something or someone touches the wires from
two different electric fences, and synchronises the output pulses so that
the potentially dangerous condition of receiving more than one pulse per
second is avoided.
The magnitude and frequency of the electric fence pulse is restricted by
safety standards such as IEC60335.2.76. This limitation is specifically
intended to ensure that a shock received from the energizer (and hence
the fence) is safe for humans. An important part of the safety requirement
is that the person receives no more than one shock per second. When
the pulses are one second or more apart, the human body treats them as
separate events and the heart is unaffected. Receiving more than one
pulse per second can interrupt the natural rhythm of the heart.
Although international safety standards require a 2.5 metre gap between
live wires powered from two different unsynchronised energizers, through
neglect or ignorance this is often not adhered to. For example live wires
running down both sides of farm dividing fences are a common site in
rural Australia.
An energizer running our patented Auto-SyncTM technology can
synchronise with any brand of energizer provided that energizer conforms
to international standards regarding pulse timing.
If synchronisation cannot be achieved or is lost, the energizer will not shut
down. It will continue to operate as though no foreign signal were present
on the fence (i.e. its regular pulse frequency and energy output).
1.5 Solar Panels
1. Mount solar powered energizers so that the solar panel is facing
the noon sun (due north in the Southern hemisphere, due south in
the Northern hemisphere, and at an angle of degree latitude plus
10 degrees). If in doubt, confirm with an online solar panel angle
calculator.
2. Solar panels need as much direct sunlight as possible, preferably
full sun all day. Unlike small solar powered items such as

6
calculators, all JVA solar-powered energizers need direct
sunlight to generate enough electricity to charge the battery.
3. The solar panel also needs to be clean to operate properly. Clean
off any dust or dirt using a damp cloth.
1.6 Rechargeable Batteries
1. The SV5/SV10 contains a rechargeable sealed lead acid (SLA)
battery, while other JVA MB energizers are compatible with lead
acid batteries. SLA battery life is shortened considerably if it is
a) left in a discharged state or;
b) exposed to high temperatures.
2. When not in use store the solar energizer in such a way as to allow
the panel to get as much light as possible, say on a window sill
with the panel facing out. Take the unit out into sunlight for a few
hours once every month to keep the battery from self discharging.
3. WARNING
SLA batteries can produce hydrogen. The energizer case is
designed to release hydrogen gas to prevent an explosion. Do not
take steps to further seal the case. Return the unit for repair if the
O-ring seal has become damaged.
1.7 Other
1. Keep the SV5/SV10 from being immersed in water and out of
extreme heat.
2. Be aware that thieves target solar powered items, so a padlock
may be useful in securing the SV5/SV10 to a fence post.

•Battery life maximization works by slowing the frequency of high voltage pulses just before the
battery dies to keep the energizer going for as long as possible without damaging the battery.
•The over discharge battery protection will stop the energizer when the battery is flat and flash the
status LED twice each second. This stops too much charge being pulled from the battery and
prevents permanent damage. The energizer will automatically restart once the battery voltage
returns to a normal level.
•The reverse battery protection protects the energizer from damage in the event you are having a
bad day and connect the external battery the wrong way around.
•The MB series of energizers seals the electronics inside a durable UV Stable case to protect
from ants, moisture and dust to maximise reliability.
•Overload indication warns you if your fence is heavily loaded by flashing a warning LED and
alerting you with a short audible beep.
•The MB series utilizes the latest digital microcontroller technology to extend battery life, provide
useful feedback on the energizer status, and increase reliability and performance.
•The audible alarm will sound in the event of a serious error for 30 seconds and then shut down for 7
minutes before sounding again.
•The Auto Recover feature will attempt to recover the energizer from severe errors which causes the
energizer to stop working. This automatic recovery process will occur at 7 minute intervals.
•Our patented Auto-SyncTM technology to help keep your fences safe.
•Power on demand automatically increases the power to heavy fence loads.
^To use with a solar panel, an external 12 volt sealed lead acid battery, solar panel and solar
regulator are required (not supplied with this kit).

3.2 Energizer LED and LCD Display
This feature is included on all units.
Status red LED –This LED has multiple functions. These are listed
below.
•Flashes slowly (once per pulse) when the load exceeds an
acceptable level indicating that the fence probably has a fault.
Operating in the overloaded condition for extended periods of
time will NOT harm the energizer. See Common Energizer
Problems below.
•Flashes twice in quick succession (2 flashes per pulse) to
indicate the battery is low. Arrange to change or recharge the
battery. See Common Energizer Problems below.
•Flashes an error code if an internal error causes the energizer
to shut down. See Common Energizer Problems below.
Energizer OK green LED –Flashes with each pulse to show the unit is
on and operating correctly.
Kilovolts display –Shows the voltage on the output terminals of the
energizer. The higher the voltage the more effective the fence will be.
Joules display –This new feature allows you to see how much energy
the energizer is storing for each fence pulse. On smaller fences the
voltage will be high but the energy may be low. On larger fences as the
voltage starts to drop, the energizer will ramp up how much energy it is
storing between high voltage pulses to try and maintain a good fence
voltage.
Power Supply Voltage display –When the energizer is turned off it will
display the power supply voltage. This is useful for quickly checking what
the battery voltage is.
3.3 Power Button
The power button turns the energizer on or off, and silences the beeper.
•If the energizer is off, push the power button to turn it on.
•If the beeper is giving an audible warning, push the power button
to silence the beeper for 10 minutes.

4 Installation
4.1 Mounting the energizer
If possible keep the energizer in a cool and dry environment (either
indoors or at least well covered) to maximise reliability. When mounting it
there are a number of options. To deter any water ingress, keep the
energizer upright when located outdoors.
•Wall Mount: The energizer may be mounted from two 12 gauge
screws at 5.5cm centres, OR
•Lay or stand the energizer on a shelf, OR
•Thread wire or string through the keyholes to hang the energizer,
OR
•Hang the energizer from a single nail or hook.
4.2 Connecting to the Fence (Standard)
The electric fence requires a dedicated ground/earth system. Drive at
least three earth spikes into the ground to a depth of at least 1.2m. Attach
a wire from the Green Ground (Earth) Terminal on the front of the
energizer to the earth spikes in the ground.
For full power connect a wire from the Red Fence Terminal on the front of
the energizer to the live wire of the fence. For half power connect a wire
from the Yellow Fence Terminal on the front of the energizer to the live
wire of the fence.
4.3 Connecting to the Fence (Bi-Polar)
The electric fence requires a dedicated ground/earth system. Drive at
least three earth spikes into the ground to a depth of at least 1.2m. Attach
a wire from the Yellow (Half Power) Terminal on the front of the energizer
to the earth spikes in the ground. Connect the Red Fence Terminal to one
of the bi-polar live fence wires, and the Green Earth Terminal to the other
bi-polar live fence wire.
4.4 Connecting to Power
1. Battery Power Source: Attach the energizer to the battery and
connect the red clip to the positive battery terminal and the black
clip to the negative battery terminal. For battery choice see the
specification table.
Mains Power Source: Attach the energizer to the supplied power
pack. Plug the power pack into the mains power outlet and turn on
the switch at the wall.
The mains power pack MUST be kept indoors!
Solar Power Source: It is recommended that a solar regulator is
used in conjunction with a solar panel and a rechargeable battery.
Please refer to instructions provided with the solar regulator for
information regarding its setup. Once the solar regulator, solar
panel and rechargeable battery have been configured, connect the
energizer to the rechargeable battery. Red to positive and black to
negative battery terminals.
2. Turn the energizer ON by pushing the Power button once.

5 Operation
5.1 Electric Fences
Electric fence energizers work by discharging a short, safe, high voltage
pulse onto the fence wires. The animal will not be harmed by a pulse, but
it will remember to avoid contact with the energised fence in future.
The high voltage is discharged from the red positive fence terminal of the
energizer and this is connected to the live wires, or fence tape, of the
fence to make them “live” or “hot” wires. Live wires must be insulated
(e.g. with insulators) from earth or any other conductive material touching
earth (e.g. fence posts).
The green connection on the energizer is the earth (or ground) terminal.
Electric fences need earthing to complete the circuit: When an animal
touches the live wire of the fence a current will flow from the live wire,
through the animal, back through the ground or earth return wires to the
earth spike and back up to the energizer earth terminal.
On touching the earth terminal on the energizer or the earth spikes in the
ground, no shock should be felt. If a shock is felt on either of the above, it
is an indication that the earthing is insufficient. To overcome this problem,
extra earth spikes need to be added to the system. The better the quality
of the earthing system, the more effective and efficient the electric fence
system will be.
You should not feel a shock from the earth connection or earth rod. If you
do, the ‘earth’ is probably not sufficient. An electric fence ‘earth’ is some
metal in contact with the soil. The more metal in the earth and the higher
the moisture content in the soil the better. The larger the energizer and
the longer the fence the more ‘earth’ is required.
In very dry conditions, i.e. sandy soil, it is recommended that a dedicated
earth wire be added to the fence line which in turn should be connected
to the energizer earth and the ground/earth spikes
For best results place the energizer in the middle of long lines of fence. A
cartwheel pattern of farm fences with the energizer positioned centrally is
more effective than a tree arrangement with the energizer at the base of
the trunk with many branches.
The fence and the earth voltages can be measured using an electric
fence digital voltmeter or digital electric fence directional fault finder (the
JVA Electric Fence Fault Finder).

5.2 Benefits of Electric Fences
•An electric fence offers a psychological barrier as well as a physical
barrier.
•The risk of injury to livestock is lower than with barbed wire fences.
•Electric fences cost less to install and maintain than conventional
fencing. Users enjoy low maintenance costs because their stock stays
off the fence.
•Their use is versatile -
-they can be permanent or portable systems,
-they can be arranged in variety of designs to suit needs
-they are quick and easy to erect
•They improve pasture and grazing control.
•They can improve existing fence life due to less physical pressure.
•Easy to set up compared to a traditional fence.
5.3 Earth Return System
The Earth Return (also called Ground Return) configuration is the most
common method for electric fences, particularly smaller fence
applications like “strip grazing”, due to its lower cost and ease of setting
up. The fence live wire(s) are electrified and rely on the dirt to complete
the circuit back to the energizer Earth terminal when an animal touches
the fence.
The electrical
circuit is closed
between the fence
and the ground
when the animal
touches the fence
A good circuit requires adequate current flow
through the ground (through moist soil)
Earth
stake

15
5.4 Fence Return System
The Fence Return configuration for electric fences is used where the soil
could be too dry to complete the circuit, or the animals are likely to try to
force their way through between the fence wires. In this system earth
wire(s) are also run along the fence with the live wire(s) to provide a low
resistance path for the current to return to the energizer. In this system if
the soil is moist enough it will also function as a return path for the current
when the animal touches the live wire, but if the soil is not moist or has
poor conductance, this system will keep your fence effective provided the
animal touches both a live and the earth wire simultaneously.
Due to the dry soil,
there is not adequate
current flow in the
ground, and a good
circuit is not completed
The circuit is closed when the
animal nudges both the live and
Earth wires of a fence
The earthed fence wire provides
the current flow required to
complete the circuit when the
ground can not.

5.5 Bi-Polar System
A Bi-Polar fence is a combination of both the earth return system and the
fence return system. The benefits are that
1) If either the positive OR negative fence wires are loaded with a
fault and have a low voltage, the other wire will not be affected by
the fault and still have good voltage on it.
2) A bi-polar fence will interfere with wireless signals (like digital TV)
less because the electrical noise generated by the fence will
cancel itself out.
3) It is less affected by parasitic elements of the fence, which means
it can power longer fences more effectively.
5.6 Earthing Your Energizer
The best way to earth your energizer is using a 1 meter galvanized earth
stakes. If the earth stake is too rusty it may not work properly. The best
place to locate the earth stake is somewhere close to where the fence
starts and that is kept damp like a garden bed, a water course, or the
overflow from a rain water tank. Do not connect the earth of your
energizer to a metal shed or the same earth your home electricity system
uses. It is also advised not to use any metal water pipes as this could
lead to someone receiving a shock from a tap.
5.7 Semi-Permanent and Permanent Fences
Steel posts are the quickest and easiest way to set up a fence, but timber
and fibreglass posts can also be used. Make sure that the wires are tight
enough that there is no sagging. 2.5mm galvanized fence wire is
recommended as poly tape or rope will degrade and break over time.
Safety signs need to be fitted as per the requirements outlined in the
“General requirements for electric fences” part of this manual.
The electrical circuit is fully
closed when the animal touches
both +ve and -ve wires
Where the ground permits good current flow (moist soil),
current can flow in both directions to complete the circuit

Stake

17
5.8 The Importance of Insulators
If the live wire is not well insulated the fence load will be much higher, this
means for any given length of fence the voltage will be lower. Pieces of
wood and garden hose are not good insulators. Use the ones made for
the job and you will get a better result.
In a fence return system the earth wire(s) do not need to be insulated, in
fact if you are using steel intermediates the more times the earth wire
touches a metal post the better it is “earthed”.
UV stable poly insulators will last much longer than non-UV stable
plastics. Plastic insulators are not as susceptible to fracture as ceramic
insulators. However, ceramic insulators are better in grass fire prone
areas as they do not melt.
5.9 Maintenance
On permanent fences maintaining the fence is important, especially
during the warmer months when plant growth is at its highest and after
any large weather events.
1. Check the fence voltage using an electric fence volt meter. The
JVA fault finder will also detect faults and direct you towards them.
2. Keep vegetation away from the fence. If it touches the fence it will
reduce its performance. Along permanent fence lines you may
wish to use a weed killer to deter any growth.
3. Check that nothing has fallen against the fence and that the wires
are not broken or have been unclipped from insulators.
The energizer battery must be checked. If the energizer is flashing a low
battery warning it is time to recharge or replace the battery

The intelligent JVA series of energizers will self diagnose and report their
status (See Errors and Error Codes) on the LED and LCD displays.
6.1 Moisture and Ants
Moisture and Ants should not be a significant problem for the JVA range
of energizers as they come in a weatherproof case. Still, where possible,
keep the energizer protected from the weather.
6.2 Lightning
The JVA range of energizers is covered with a three-year warranty that
excludes Lightning. Surge protection components inside the energizer are
fitted to reduce the risk of damage by lightning. However, nature is
capable of performing more extremely than can be tested for in the
laboratory; to ensure the wellbeing of your JVA investment for the longer
term, it is recommended that a Lightning Protection Kit is installed to
prevent lightning damage and possible costly repairs.
6.3 Flat Batteries
The JVA series of energizers require a battery that is in good condition to
run correctly. The energizer will protect the battery by slowing down and
eventually stopping altogether as the battery charge is depleted. For best
results, check on the energizer at regular intervals. If you are not getting
the expected life from the battery consider having it checked by an auto
electrician.
The JVA series of energizers indicate a depleted battery by flashing the
red Error LED twice (see “Parts of the energizer” above).
If the battery fails it should be recycled, not sent to land fill. Return it to
the manufacture if unsure.
6.4 Battery Replacement (SV5/SV10 only)
The JVA SV series of energizers contain a sealed lead-acid (SLA) battery
that is charged by the solar panel. If the unit indicates a depleted battery
is will flash the red error LED twice. The unit should be turned off and
placed in full sun for 2 to 3 days to allow the battery to fully charge.
If after this time the unit still indicates a depleted battery, or the life of the
battery is reduced, the battery may be damaged or at the end of its life
and should be replaced.
