WARNING
Risk of shock!
►High voltages exist inside the electric fence energizer and on the fence terminals.
►High voltages are also retained for a while after switching o󰀨. It is advisable to wait for at least 10
minutes before opening the energizer case.
►Before working on the high voltage wiring of an electric fence, it is recommended that the energizer
be turned o󰀨 and an intentional short circuit be placed from the fence live wires to earth. This is a
precaution against the energizer being turned on while work on the fence is in progress

1. IMPORTANT NOTES – PLEASE READ
1.1 Electric Fences
1. Electric fences must be installed only in accordance with the relevant Standards and
Workplace Health and Safety regulations.
2. Electric fences are designed to deliver a short, safe shock. Do not let children play near them.
3. Electric fences must have warning signs. These must comply with IEC standards and should
be prominently displayed on electric fences at distances specied by the country in which
they are installed.
4. In order to operate e󰀨ectively, electric fences must be well earthed. This involves the use of
galvanized, *steel stakes/spikes/rods/electrodes (various terms are in use) driven into the
earth at a depth of at least 1.2m. A minimum of 3 earth stakes are recommended at the
energizer. Additional earth stakes may be required on higher powered energizers and along
the fence in dry soil conditions. The deeper the earth stakes, the better.
* Hot-dipped galvanized steel earth stakes are recommended because the e󰀨ectiveness
of the earthing is reduced by corrosion at the joints. This is caused by the electrolytic
e󰀨ect resulting from a current owing through unlike metals making contact in a moist
environment.
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 energized depends on many factors, for example the
earth resistance, competition from vegetation, number, spacing and conguration of wires –
series or parallel, type/quality of insulators, resistance of wire type used, etc. Another factor to
consider is acceptable fence voltage: for some livestock situations this is 3kV, others require
more or less. Therefore the rated mileage of fence that the energizer will power e󰀨ectively is
a guide only.
3. WARNING! 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 o󰀨.
1.3 Power Supply Options
• 12V Battery (not supplied)
• 24V Battery (not supplied)
• 12V Battery with Solar panel (not supplied)
• 240Vac (via Power Pack) (13.8V DC Power Pack supplied)
The JVA MB1.5, MB3 and MB4.5 energizers have limited power supply options. For more

N.B.
►Do not connect directly to mains – use the power supply provided.
►When using a battery option, always ensure adequate ventilation is given to the battery. Lead-
acid batteries may emit explosive gases while charging!
►Always mount the power supply either indoors or undercover.
1.4 Rechargeable Batteries
If powered from a rechargeable battery, 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 very high temperatures.
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.

►The MB series of energizers has the electronics enclosed inside a durable UV stable case
to protect against ants, moisture and dust and so maximize reliability.
►The overload indication warns if the fence is heavily loaded by ashing a warning LED and
alerting 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
cause the energizer to stop working. This automatic recovery process will occur at 7-minute
intervals.
►Power on demand automatically increases the power to heavy fence loads.
►To use the MB Range with a solar panel, an external 12 volt sealed lead-acid battery, solar
panel and solar regulator are required.

JVA AgriRange Energizers
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
energized fence in future.
The high voltage is discharged from the red, positive fence terminal of the energizer and this is
connected to the fence wire or electric fence tape to make them live or ‘hot’ wires. Live wires must
be insulated from earth or any conductive material touching the ground, e.g. fence posts).
The green Terminal connector 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 ow from the live wire, through the animal, back through the ground or the earth return wires
to the earth stake and back up to the energizer earth terminal thereby completing the circuit. (See
Fig 1 below)
On touching the earth terminal on the energizer or the earth stakes 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 insu󰀩cient. To
overcome this problem, extra earth stakes need to be added to the system. The better the quality
of the earthing system, the more e󰀨ective and e󰀩cient the electric fence system will be.
The more earth stakes in the ground and the higher the moisture content in the soil, the better
the system will function. The higher powered (higher joule rating) the energizer and the longer the
fence, the more earthing is required.
In very dry conditions and sandy soils, it is recommended that a dedicated earth wire be added
to the fence line. This in turn should be connected to the energizer earth and the ground/earth
stakes. (See Fig 2)
For best results locate the energizer as centrally as possible in a fencing layout.
The fence and the earth voltages can be measured using an electric fence digital voltmeter, or a
digital electric fence directional fault nder, such as the JVA Electric Fence Digital Directional Fault
Finder.
5.2 BenetsofElectricFences
► An electric fence o󰀨ers 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 o󰀨 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 as a result of less physical pressure on the fence
►They are easy to set up compared with traditional fences.

5.3 All-Live Wire, Earth Return System
The Earth Return (also called Ground Return) conguration is the most common method of
conguration for electric fences, particularly smaller fence applications like strip grazing. The
fence live wire(s) are electried and rely on the soil 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
The circuit is closed
when the animal nudges
both the live and Earth wires
of a fence
A good circuit requires adequate current ow through
the ground (through moist soil)
5.4 Live-/Earth-Wire Fence Return System
The live-/earth-wire fence return conguration for electric fences is used where the soil is too dry to
complete the circuit adequately, 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 e󰀨ective
provided the animal touches both a live and the earth wire simultaneously.

5.5 Earthing Your Energizer
The best way to earth an energizer is to use a minimum of 1.2 metre galvanized earth stakes.
If the earth stake is too rusty it will not work properly. The best place to locate the earth stake is
somewhere close to where the fence commences and if possible where the ground is damp such
as a garden bed, a water course, or the overow from a rain water tank. (South African regulations
require a minimum of 3 earth stakes to be located close to the energizer.) Do not connect the earth
of the energizer to a metal shed, metal pipes or utility earthing system as this could lead to shock
from tap, showers etc.
5.6 Semi-Permanent and Permanent Fences
The quickest and easiest way to set up a permanent fence is to use steel posts, but timber and
berglass posts can also be used. Make sure that the wires are tight enough to eliminate sagging.
2.5mm galvanized fence wire is recommended as poly tape or rope will degrade and break over
time. Warning signs need to be tted as per the requirements outlined in the, General Requirements
for Electric Fences section of this manual.
5.7 The Importance of Insulators
If the live wire is not well insulated the fence load will be much higher. This means that, for any
given length of fence, the voltage will be lower. Pieces of wood and garden hose are not good
insulators! For reliable results standard insulators designed for this purpose are recommended.
In a live-/earth-wire fence return system the earth wire(s) do not need to be insulated. In fact,
if using steel intermediates, the more times the earth wire touches a metal post the better it is
earthed/grounded.
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, re prone areas as they do not melt.
5.8 Maintenance
Maintaining permanent fences is important, especially during the warmer months when plant
growth is at its highest and after any disruptive weather events.
1. Check the fence voltage using an electric fence voltmeter. 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.
The judicious use of weed killer may be used if so wished 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.
4. Check the condition of the earthing system for corrosion and loose joints.
5. Check that lightning diverters are all still operational.
6. Check and tighten any loose line clamps along the fence.
7. Check the energizer battery. If the energizer is ashing a low battery warning it is time to
recharge or replace the battery.

6. COMMON ENERGIZER PROBLEMS
The most common problems with electric fence energizers are:
• Flat batteries
• Lightning
• Moisture and ants
• Blown fuses
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 Flat Batteries
The JVA series energizers, to run e󰀨ectively, require a battery that is in good condition. 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 not receiving the
expected life from a battery consider having it checked by an electrician.
6.2 Lightning
The JVA range of energizers is covered with a two-year warranty that excludes lightning. Surge
protection components inside the energizer are tted 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 long term, it is recommended that a Lightning
Protection Kit is installed to prevent lightning damage and possible costly repairs.
6.3 Moisture and Ants
Moisture and ants should not be a signicant problem for the JVA range of energizers as they are
protected in a weatherproof case. However, where possible, keep the energizer protected from
the weather.
6.4 Blown Fuses
The fuse used is a self-resetting type. Disconnect the power for a minute and then reapply the
power. If the unit still does not power up, return it to a service centre.

6.5 Errors and Error Codes
The JVA energizer may stop and display error codes. The error codes are displayed in two places.
The rst of these is on the Status (red) LED, where it will ash rapidly a number of times. The
number of these ashes corresponds to the Error Code. The second place is on the LCD, where
it will display a message.

Errors 2 and 6 indicate the battery voltage is either too low or too high. The energizer will restart as
soon as the voltage returns to the correct range. All other errors indicate an internal malfunction.
Should the error continue to re-occur, please return the unit to a qualied service centre for repair.
There are no user-serviceable parts inside the energizer. All internal fuses will automatically reset
themselves.
7. COMMON FENCE PROBLEMS
The most common problem with electric fences is low voltage on the live wires caused by
• Inadequate earthing/grounding
• Shorts on the fence
For tips on fence construction please refer to an Electric Fencing Manual.
7.1 Testing the Earthing/Grounding System
The earth/ground is essential to all electric fence systems. Larger energizers require more earth
spikes/stakes/rods/electrodes.Additionally, all energizers require a low resistance wired connection
from the energizer earth terminal to the earth stake.
Short the end of your fence to earth by hammering a metal stake into the soil and connecting
this to the live fence wire. Using an electric fence voltmeter or a JVA Electric Fence Fault Finder,
(Do not use a standard multimeter.) check the voltage is at the earth terminal of the energizer. In
general it should be a reading less than 300 volts (0.3kV).
7.2 Testing the Fence, Finding Shorts
To test the performance of the fence or nd faults on the fence, an electric fence voltmeter is
essential, and a JVA Electric Fence Fault Finder is even better. An e󰀨ective fence will have more
than 2 kV (2000 volts).
