Product Usage Instructions

Installation
Mounting the Energizer
To mount the energizer:

1. Choose a suitable location near the fence.
2. Ensure the mounting surface is secure and stable.
3. Use the provided screws or brackets to fix the energizer to the wall or post.

Location of Energizer:

• If possible keep the energiser in a cool and dry environment (either indoors or covered) to maximise reliability.
• When selecting a location for your energiser, be mindful of thieves.

Mounting the Energiser

• It can be hung from a fence on the hook moulded into the back of the case.
• It can be hung from two screws spaced 4 cm apart horizontally.
• To deter any water ingress, keep the energiser upright when located outdoors. Do not allow the pet energizer to be immersed in water.

Connecting to the Fence
To connect the energiser to the fence:

1. Identify the fence connectors on the energiser.
2. Strip the insulation from the fence wire.
3. Connect the fence wire to the appropriate connectors on the energiser.
4. 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 energiser to the earth stake.
5. Connect a wire from the fence connector on the front of the energiser to the live wire of the fence.
6. Powering the Energiser:
   Mains Power Source: Plug the 12 volt power adapter supplied with the energiser into an AC power source and the other end into the DC socket on the side of the energiser. Turn the mains power switch on and then press the power button on the front of the energiser.
   External battery Power Source: For information on selecting a battery see the specification table in section 3.2. Plug the battery power cable into the DC socket on the side of the energiser. Then connect the alligator clips to the battery. Red to positive and black to the negative battery terminals. Press the power button on the front of the energiser. If the battery is low, the red LED will flash as the green LED flashes to indicate it is running in battery maximisation mode. If the battery is flat, the energiser will not start and the red LED will flash twice to indicate the battery requires a recharge.

NB The unit may turn on as soon as power is applied. This is a feature that will ensure the unit will turn itself back on in the case of a power failure. Press the power button and the unit will stay off until you press the power button again.

Testing the Fence, Finding Shorts
To test the fence and find shorts:

1. Ensure the energiser is powered on.
2. Use a fence tester or voltmeter to check for voltage along the fence.
3. If there is a voltage drop or no voltage at certain points, there may be a short in the fence. Inspect and repair the fence as needed.

To test the performance of the fence or find faults on the fence an electric fence voltmeter is essential and a JVA Electric Fence Fault Finder is even better. An effective fence will have more than 2 kV (2000 volts).

Note: For detailed installation and connection instructions specific to electric fences in Australia, please refer to section 8 of the user manual.
This JVA products offers a 12 month warranty against faulty components and workmanship but excludes Acts of God, i.e. lightning, flood damage, etc. or malicious damage to the unit or faulty application. To ensure your eligibility for this warranty program, please retain your proof of purchase.
DANGER: Risk of Shock!
High voltages exist inside the electric fence energiser and on the fence terminals.

Important notes – PLEASE READ

Electric Fences

1. Do not allow children or elderly persons to touch the energiser or fence live wires. Electric fences are not toys.
2. Electric fences should only be installed with regard to the relevant Standards and work place health and safety requirements.
3. Electric fence should be signed: every 10m in areas with public access, every 1 km in rural areas.
4. Electric fences must have an ‘earth’ (Also commonly referred to as ground). An electric fence earth is one or more pieces of metal (e.g. 1.8m Galvanized earth rods) driven into the soil.

Energisers

1. The PET energiser places a very short, very high voltage pulse on the fence live wires approximately once every second. The fence is ‘safe’ in that the pulse is too short to cause electrocution. 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 energiser 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 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 energiser will power effectively is a guide only.
3. DANGER: The Energiser 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.

• 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. When working in this mode the red status LED will flash at the same time as the green Energizer OK LED to warn the battery is getting low.
• The over discharge battery protection will stop the energizer when the battery is flat and flash the status LED twice each second. If too much charge is pulled from the battery it will be permanently damaged and never hold the same amount of charge again. The PET energizer will automatically restart once the battery voltage returns to a normal level.
• The compact design of the PET series makes it easy to move and setup.
• 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 PET series of energizers seals the electronics inside a durable UV Stable case to protect from ants, moisture and dust to maximize reliability.
• The PET series utilizes the latest digital microcontroller technology to extend battery life, provide useful feedback on the energizer status, and increase reliability and performance.
• All energisers in the JVA PET series can be powered from mains via the 12 volt plug pack supplied with each unit, or from a battery.
  ^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).

Parts of the Energizer

1. Power Cable Input (mains 12V plug pack or external 12V battery)
2. On/Off
3. Energizer On and OK – pulse indicator (green LED)
4. Status indicator – service error, low and flat battery warning (red LED)
5. Fence connection terminal
6. Earth connection terminal

Fence Connectors

1. The earth terminal should be connected to a suitable electric fence earth rod.
2. The “Fence” terminal should be connected to the live wires of the fence.

Energiser LED Display
This feature is included on all units.

1. Status red LED – Will flash a service error code in the event there is an internal fault with the PET energizer, or a flat battery warning when the battery is flat. If the Status LED flashes as the Energizer OK LED flashes, this means the battery is getting low and the PET energizer is running in battery maximization mode.
2. Energizer OK green LED – Flashes with each pulse to show the unit is on and operating correctly.

Important Note: If there is a fault the green LED will stop flashing and the red LED will flash an error code. If the red LED flashes twice every second, the battery is low and the energizer has stopped operating to protect the battery. For all other error codes the energizer needs to be returned for servicing.

Operation

Recharging
External 12 volt battery: The external 12 volt battery can be recharged using either a solar panel e.g. a PTE2273 5W Solar Kit, or a 12 volt battery charger. The PET100 does not need to be disconnected or turned off while charging the battery. Always ensure adequate ventilation is given to the external 12 volt battery while charging.

Electric Fences
Electric fence energizers work by placing a short, high voltage pulse on fence wires. Although the voltage is very high (up to 10,000V) the pulse is too short to cause electrocution. The result is a zap similar to a static electricity shock from a car seat. 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 a JVA Electric Fence Fault Finder.

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 a of designs to suit different needs and environments
  • they are quick and easy to erect
• They improve pasture and grazing control.

Applications
Your PET energizer is perfect for strip grazing, temporary yards or horse corals and keeping your pets out of the garden. Please check with your local animal protection society as to whether they allow this. At less than 1 stored Joules the PET is ultra safe, being more than 10 times lower than the limits as set in the relevant Australian and International Standards. The shock from a PET energizer is about the same as you get from static when sliding out of a car seat in winter. It is very light and portable, will run for months from a large 12V battery and even warns you when the battery is getting low.

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 PET energizer Earth terminal when an animal touches the fence.

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 energiser. 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.

Earthing Your PET Energizer
The best way to earth your PET energizer is using a 1 meter galvanized earth stake. 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 PET 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.

Pest Control
The PET energizer is perfect for powering snail control tape. The snail fence is an excellent environmentally friendly alternative to using toxic chemicals to protect your garden from snails and slugs.

Strip Grazing/Pet Control There are many options available when setting up temporary fences, but the most common is a single live wire set at height that the animals cannot step over or crawl under without getting a shock. For posts there are a range of plastic tread-ins, round metal posts with insulated “pig tails” or Y posts with pin lock insulators.
For these short temporary fences, poly tape or rope woven with fine stainless steel conductors is a good choice. It is light, highly visible and can be easily rolled up when not in use. Safety signs need to be fitted as per the requirements outlined in the “General requirements for electric fences” part of this manual.

Semi-Permanent and Permanent Fences
Steel posts are the quickest and easiest way to set up a fence, but timber and fibre glass 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 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.

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 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. 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.
4. The PET energiser battery must be checked. If the PET energiser is flashing a low battery warning it is time to recharge or replace the battery.

Common Energizer Problems

The most common problems with electric fence energisers are:

• Moisture and Ants
• Lightning
• Flat batteries

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. Keeping the energizer off the ground and mounted vertically will minimize both these issues.

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 damage more extreme 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.

Flat Batteries
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. If the battery fails it should be recycled, not sent to land fill. Return it to the manufacture if unsure.

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.

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 pet energizer. In general you should see a reading less than 300 volts (0.3kV).
