Gallagher 3E1164 Power Fence Systems User ManualINTRODUCTIONThe earlier generations of Gallaghers were farmers. And it was a typical farmer’s approachto solving farm problems that helped us lead the world into the electric fencing age. Fromthe 1930’s we developed, on our own family farm, animal control systems to make farmwork easier. Today we are known in over 100 countries.Gallagher Power FenceTM Systems are recognised for decreasing costs and increasingprofits for farmers throughout the world. Our economical and practical fencing providesincreased efficiency in controlled grazing through subdivision. Increased stocking ratesand fodder conservation are the prime contributors to better farm profits and farmershave reaped the benefits of upgrading non electric fences, fencing out wild animals andprotecting both stock and pasture.This manual is designed to help you achieve the best possible results from your GallagherPower FenceTM System. It will help you design your fence system and give suggestions forthe fence materials, hardware, accessories, tools and testers you will need. For maximumpower with minimum maintenance it is important to follow the principles of fenceconstruction and energizer earthing closely. If you’re not prepared to do it properly, beprepared to accept less than optimum performance.Thank you for choosing Gallagher - I’m sure you’ll be satisfied with your decision for yearsto come.W.M.

Gallagher 3E1164 Power Fence Systems User ManualReasons for Using Power Fencing1. REASONS FOR USING POWER FENCINGAnimal Control Keep domestic animals in.Keep wild animals and vermin out.Separate different groups of animals.Allow rationing of crops and pastures.Fence off eroding areas, trees, riversand roads.The Benefits of Power Fencing Affordable. Easily constructed and maintained. Light weight and easily transported. Durable because of low physicalcontact. Easily modified. Less animal hide and pelt damage. Deterrent to trespassers and predators.Profitability Increase milk and meat production withfresh, short, highly palatable pasture. More subdivision ensures animalmanure is spread more evenly over thewhole grazing area.2. HOW DOES POWER FENCING WORK?A power fence is a psychological barrierthat keeps farm animals in and wildanimals and vermin out – even over longdistances.A pulsed electric current is sent along thefence wire, about one pulse per second,from an energizer which is earthed. Whenthe animal touches the fence it completesthe circuit between the fence and theground and receives a short, sharp but safeshock. The shock is sufficiently memorablethat the animal never forgets. If theground is very dry, the fence may requirean earth return wire (see Figure 4.7(b)).A power fence is a psychological barrierso doesn’t need great physical strength.However, it must be well designed andconstructed to absorb some pressure fromanimals, snow and wind. The energizermust have enough power for the length offence and for the animals being controlled.Figure 2.15
Gallagher 3E1164 Power Fence Systems User ManualWhere to Start3. WHERE TO STARTThe question we are asked the most is“where do I start?” This manual is the firststep to choosing the fence that’s right foryour needs and property. The more youknow before you start, the easier andmore economical your fence installationwill be.There are two types of fence, permanentand portable, and three ways to powerthem: mains, battery and solar/battery.Unless you want a temporary or removablefence, a permanent power fence willbe the best choice. Permanent powerfencing is economical and easy to installand operate. Portable power fencing is aneffective temporary barrier for short-termanimal control and rotational grazing. Hereare the basics for permanent and portablefences.3.1 Permanent Power Fence:ACDIEKFHGBLADCHJFigure 3.1(a) - Permanent Cattle FenceFEKIGLBJFigure 3.1(b) - Permanent Cattle Fence with Earth Return WireAEnergizerDPost insulatorGGreenJJoint clampsBEarth stakeEWire tightenerHRedKStrain postCStrain insulatorFWarning signICut out switchLLine postHere’s what you’ll need: Electric fence energizer Earth (ground) system Leadout cableThe fence itself: 6End strain insulatorsLine post insulatorsJoint clampsCut out switches Electrified gatesWire tightenersPosts2.5mm high tensile galvanised wireStaplesOffset brackets (optional)Refer to “4.

Installing a Permanent Power FenceTMGallagher 3E1164 Power Fence Systems User Manual4. INSTALLING A PERMANENT POWER FENCETM4.1 Planning the fence layoutDraw a plan of the fence system youwould eventually like to have. This will helpyou identify the length of new electricfence, the length of existing fence to beelectrified (using offsets) and the length ofleadout from your energizer to the electricfence. On the plan show the power supply,the direction the power flows, gatewaysand cutout switches and electrificationof remote areas. Allow for two or moresections to be electrified by a separateenergizer in the future. You might alsoneed a training paddock for livestock.If your electric fence system is severalkilometres (miles) from the mains powersupply, see “Electrifying Remote Areas”under section 4.4.1 Install the Leadout formore information.Figure 4.1 shows an ideal layout on a flatrectangular farm. Use the same principleon all properties whatever the shape orsize. It is the number of paddocks that isimportant not the size. Plan the number ofpaddocks to allow for controlled grazing,easy conservation of hay/silage and longrotations in times of slow pasture growth.Make a lane, race or roadway down thecentre or side of the area to be subdividedor fenced. This allows stock to be checkedand moved easily. If necessary, waterpipes can be laid down the lane. Paddocksshould be as close to square as possiblefor even grazing. Long narrow paddockscreate footpaths with overgrazing at thefront and undergrazing at the back.Avoid having electric wires running parallelwith telephone and power lines (refer to“8. Safety requirements and regulations”).Figure 4.1 - Ideal fence layoutEnergizerCut-out switch8
Gallagher 3E1164 Power Fence Systems User ManualHANDY HINTInstalling a Permanent Power FenceTMHANDY HINTCut Out Switches (G6076/G6087):These isolate different sections of thefence when looking for faults. Place themat gateways or junctions where eithersingle or multiple fence lines can be turnedoff.Rough, stony or steep areas:With power fencing it is easier and lessexpensive to “zig zag” around rather thango straight over rough, stony or steepareas. These rough areas require moreposts and tie-downs, and possibly moremaintenance in the future.If possible level the area first and re-grassthe area because animals standing on grassget a greater shock than when standing onbare soil. Re-grassing also prevents erosionand weed growth.HANDY HINTIf you farm sheep intensively, you maywant as many as 100 paddocks. Thismeans the sheep can be moved daily ontoa fresh paddock using a three monthrotation during slow or zero growthperiods. When there are lambs and ewesduring spring, two or more flocks can begrazed on a faster rotation.Stock will respect all fences if most of yourfarm fences are electrified. This meansinternal subdividing fences can then havefewer wires so you can build more fencingat a lower cost per metre (yard). Powerfencing also makes fencing dams, rivers,trees and erosion prone areas easier.On dairy farms 30–50 paddocks are usuallyenough. Cattle are easy to strip graze withonly one wire when longer rotations arenecessary during slow growth periods.9

Installing a Permanent Power FenceTM4.2 Selecting the correctenergizerThe energizer is the heart of the fencingsystem so select carefully. Gallagherenergizers guarantee a high-energy pulsethat will effectively control animals evenover long distances. They are identified bytheir stored energy (measured in joules)e.g. M1200 has approx. 12 stored joules,MBX2500 has approx. 25 stored joules.When choosing an energizer, compare thestored energy figure. Stored energy is themost accurate measure of an energizer’scapability because it is constant and notaffected by external conditions like poorearthing.Electric fence systems tend to grow, sopurchase an energizer that will power thefinal fencing system. There is a range ofGallagher energizers (also called units,controllers, chargers or fencers) for allsituations.Mains powered energizers are the bestchoice where you have reliable mainspower. Mains/battery powered energizerslike Gallagher SmartPower MBX energizerscombine the advantages of mains powerwith a battery backup. They are a practicalGallagher 3E1164 Power Fence Systems User Manualchoice for providing guaranteed animalcontrol and a must in regions where mainspower is unreliable.Solar powered battery energizers are thelogical choice for remote areas wherethere is no mains power. A solar panelcharges a deep cycle battery by convertinglight directly into electricity. The batterystores this electricity to operate the batterypowered energizer. This enables theenergizer to operate at night or duringperiods of low sunlight. The brightness,the amount of light and the size of thesolar panel all determine how muchelectricity is produced.Note: Solar systems require individualdesigns for different locations. Contactyour Gallagher dealer for advice.Portable battery powered energizersare generally operated by a 12 voltrechargeable battery or a 9 volt disposabledry cell battery.The B11 battery powered strip grazer isdesigned for single reel systems and canbe operated by 6 “D” size batteries or a 12volt rechargeable battery.ENERGIZER FACTSStored energy versus output energy?Stored energy: Power from either a mainspower source or a battery enters the energizerand is stored in capacitors as stored energy.The higher the stored energy figure the morepowerful the energizer.Output energy: A timing circuit in theenergizer sends the energy down the fenceline approximately once a second through atransformer as output energy. Output energycan vary depending on fence conditions andnational standards.12Batteries: Where a rechargeable battery isused to power the energizer, the battery willneed to be recharged as necessary dependingon the size of the energizer, battery capacityand amount of use. So choose a battery thatwithstands regular charge and dischargecycles without damage – such as a marine ordeep cycle type. We do not recommend usingautomotive batteries because they are designedto supply very high current for only a short time.
Gallagher 3E1164 Power Fence Systems User ManualFor a permanent power fence systemchoose from a mains powered energizer,a mains/battery powered energizer or apermanent solar powered energizer.Energizer selection is determined eitherby acreage to be fenced or the length offence.Installing a Permanent Power FenceTMBoth are estimates because the distanceof fence can vary between two farms ofthe same area because of the number ofpaddocks, terrain or conditions. For drycountry conditions, energizers have provento work effectively over greater distances.Energizer Selection Chart - by Farm SizeSize of PropertyEnergizer 4ha.

Gallagher 3E1164 Power Fence Systems User Manual4.3Installing the Energizer4.3.1 Install the earthing(grounding) systemWhy does the energizer need an earthsystem?The earth is half the circuit of your fencingsystem. Electrons travel from the energizer,along the fence wires and back throughthe ground to the energizer to completethe circuit. Like a radio antenna collectssound waves, the earth system collects theelectrons. The earth must be as conductiveas possible for the fence to give the animalan effective shock. A simple guide is oneearth stake for every five joules of storedenergy with a minimum of three earthstakes e.g. M1200 (12 joules) - three stakes, MR5000 (50 joules) - ten stakes. Insandy or pumice soils more stakes will berequired.Energizer SizeEarth stakesrequiredUp to 15 J3 Stakes minimumUp to 25 J5 Stakes minimumUp to 35 J7 Stakes minimumFigure 4.7 - Earth stakes requiredIt is important to follow therecommendation above to get themaximum benefit. The number of earthstakes will vary depending on the powerof the energizer and the soil type: highpowered energizers need more stakes thanlow powered energizers, dry soils needmore stakes than wet soils.HANDY HINT4-3-2-1 Rule for Earth stakes :4Metres between earth stakes3Earth stakes minimum required2Metres min. length of earth stake1Wire connecting all earth stakesInstalling a Permanent Power FenceTM(reference earth) installed close to theenergizer with a separate wire or cableconnected back to the energizer earthmonitor terminal.

At least 10m (33ft) from an electrical ortelephone earth (the further away thebetter) At least 10m (33ft) from metal pipescarrying domestic or stock water At least 20m (66ft) from any dairy shedpipework Not connected to, or touching steel oriron clad buildings Protected from machinery and stockdamage Away from fertiliser, animal urine andmanure (corrosion)If the earth system has to be somedistance from a high powered energizerthe connecting wire must be highlyconductive e.g. 250 m (820 ft) away use1 x aluminium coated wire (G9290), 500m 1640 ft) away use 2 x G9290 wires inparallel.WARNING:Use galvanised earth stakes. Rusty orcorroded stakes will not work.Do not allow bare wires to touch an ironclad building - use double insulated cable.Note: Some modern energizers with earthmonitors, e.g. SmartPower energizers,require a small independent earth stake17

It should be testedat least once a year or at the height of anydry period to ensure the earthing capacityis sufficient for the joule rating of theenergizer.Note: In drought conditions it may benecessary to water the earthing system.4 wire earth return system10m Figure 4.8 - 4 wire earth return systemMain causes of a poor earth are:Rusty or corroded earth stakesBroken earth wire connecting the stakesNot enough earth stakesStakes too close together or too shortPoor connections at the stakes or in theconnecting wireUsing a Digital Volt Meter (DVM) (G5030or G5035) measure the voltage betweenthe wire connecting through the earthstakes to the energizer earth terminal andan independent earth stake. This stakeshould be a galvanised metal rod, minimum200mm (8”) long, and placed one metre(3ft) away from the earth rods or as faraway as your DVM cable will reach (seeFigure 4.9).Note: If you are using a SmartPowerenergizer the earth monitor/alarm willindicate when the earth system requiresattention (see Figure 4.6).There should be no reading on the DVM,however up to 200V (0.2kV) is acceptable.If the voltage is higher than this, switch offthe energizer, drive in more earth stakes atthe recommended spacings and connectthem to the existing earth system until thevoltage is down to the acceptable level.Meterkv100 m (300 ft)Digital Volt Short the fence out at least 100m (330ft)away from the earth system by usingseveral steel stakes between the live wiresand the ground.
