2 Important notes –
PLEASE READ
2.1
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 must have an ‘earth’. An electric fence ground is one or more pieces of metal (e.g. 1.8m Galvanized earth rods) driven into the earth to a depth of at least 1.2m.
2.2
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.
2.3
Power Supply Options
The JVA MB series of electric fence energizers can be powered from a range of power sources.
12V Battery
24V Battery
12V Battery with Solar panel

5 Important notes – PLEASE READ
5.1
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.
5.2
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 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.
5.3
Rechargeable Batteries
1. JVA’s MB and SV energizers are compatible with sealed lead acid
(SLA) 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 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 energizer out into sunlight for a few hours once every month to keep the battery from self discharging.
3. WARNING
SLA batteries can produce hydrogen. JVA Energizers that come with internal batteries are 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.
5.4
Other
1. Keep any energizers 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 energizer to a fence post.

JVA Energizer User Manual
6.2
Connecting to the Fence
3. The electric fence requires an ‘earth’. Drive a galvanized earth rod into the earth. Attach a wire from the Green Earth Connector on the front of the energizer to the earth stake.
4. Connect a wire from the Red Fence Connector on the front of the energizer to the live wire of the fence.
5. Powering the Energizer:
Mains Power Source (M1.5, M3, MB1.5, MB3.0, MB4.5) : Plug the mains power cable (M1.5, M3) or the power adapter (MB1.5,
MB3.0, MB4.5) supplied with the energizer into an AC power source and the energizer. Turn the energizer ON at the On/Off switch.
Battery Power Source (MB1.5, MB3.0, MB4.5 & RSG1): Attach the battery, red to positive and black to negative battery terminals.
For battery choice see specification table 3.2
. Turn the energizer
ON at the On/Off switch.
Solar Power Source (MB1.5, MB3.0, MB4.5): It is recommended that a solar regulator is used in conjunction with a solar panel and a rechargeable battery (For battery choice see specification table
3.2). 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. Turn the energizer ON at the On/Off switch.

JVA Energizer User Manual
7 Operation
7.1
Electric Fences
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.
The high voltage comes from the Fence terminal of the energizer and is connected to the fence wire or electric fence tape to make a “live” or “hot” wire. Live wires must be insulated (e.g. with insulators) from earth or any conductive material touching earth (e.g. fence posts).
The other connection on the energizer is the ‘earth’ (or ground). Electric fences need ‘earthing’ to complete the circuit: When anything touches the live wire current will flow from the live wire, through the animal to earth back to the ‘earth’ rod and into the energizer earth terminal.
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 the better, the moister the soil the better. The larger the energizer and the longer the fence the more ‘earth’ is required.
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’ can be measured with an electric fence Digital
Voltmeter or Digital Power Probe.
7.2
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.
11
JVA Energizer User Manual
7.3
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
7.4
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.
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.
Earth
Stake
Due to the dry soil, there is not adequate current flow in the ground, and a good circuit is not completed

8 Common Energizer Problems
The most common problems with electric fence energizers are:
Moisture and Ants
Lightning
Blown Fuses (AC units only)
Flat batteries
8.1
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.
8.2
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 long term, it is recommended that a Lightning Protection Kit is installed to prevent lightning damage and possible costly repairs.
8.3
Flat Batteries (battery units only)
The JVA series 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.
8.4
Changing the Battery (battery units only)
Before you start, s ee “
Important Notes
” on page 3. If the SV2 stops as soon as the sun sets (and it has been getting 8 hours or more sun a day) or if the RSG1 battery charge does not last more than 5 days (a good battery will last 7 days and needs 18 hours to charge), the battery may need replacing. The battery is a sealed, lead acid, 6V, 4.2ah battery.
Open the unit and read the battery ah and part number before ordering a new one. These may be available from the manufacturer or through the store where the SV2 or RSG1 was purchased. This type of battery is also readily available through general electronics stores and hardware stores.
Notes:
The battery must be a rechargeable sealed lead acid battery, never use non rechargeable batteries.
The battery should last up to 5 years depending on average temperature and usage. Are you sure it needs replacing?
Lead acid batteries should be recycled, not sent to land fill.
Send it back to the manufacturer if unsure.

JVA Energizer User Manual
If you don’t feel confident in changing the battery, or can’t find the correct replacement please call us, for a small fee we will be happy to service your unit.
Steps
Attention: Take Care: Risk of electrical shock! Risk of fire (See
“Important Notes” on page 3)
1. Turn the SV2/RSG1 off. Be careful not to press firmly on the front of the case as this can sometimes turn the unit on.
2. Place the SV2/RSG1 face down on a clean working surface.
3. Unscrew the six main case screws.
4. Turn the unit over so that its face is facing up.
5. Pry the front off, note there is an o-ring seal. The seal may be stuck to either or both surfaces. If it comes out of the groove simply press it back in.
6. Disconnect the battery leads. Always disconnect the leads at the battery terminals NOT the PCB. Do not allow the wires from battery terminals to touch each other.
7. Remove the old battery.
8. Place the new battery in and secure it in the same way as the original was secured. Do not short the battery terminals.
9. Reconnect the battery leads.
10. Replace the cover ensuring the o-ring seal is in the groove and cables are NOT pinched between the lid and case.
11. While holding the unit together firmly, turn it back over onto its face and replace the six main case screws.
8.5
Dirty Solar Panels
The solar panel on the SV2 needs to be clean to operate properly and keep the battery charged. Clean off dust etc. using a damp cloth.

9 Common Fence Problems
The most common problem with electric fences is low voltage on the live wires caused by
Insufficient ‘earth’
Shorts on the fence
For tips on fence construction please see an Electric Fencing Manual.
9.1
Testing the ‘Earth’.
The ‘earth’ is essential to all electric fence systems. Larger energizers require more earth rods. Additionally, all energizers require a low resistance wired connection from the energizer earth terminal to the earth rod.
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 volt meter or a JVA Electric Fence Fault Finder (do not use a standard multimeter) check what the voltage is at the earth terminal of the energizer. In general you should see a reading less than 300 volts
(0.3kV).
9.2
Testing the Fence, Finding Shorts
To test the performance of the fence or find faults on the fence an electric fence voltmeter is essential, and a Digital Power Probe is even better. An effective fence will have more than 2 kV (2000 volts).
