Electric Fence Equipment Setup


Parmak Mag 12The components of your system should be installed and mounted inside, out of sight and LOCKED out of reach from unauthorized people.


Hang the high voltage charger from the wall and connect it to the battery, placed under the fence charger using the red and black wires that are attached to the fence charger – with the red wire to the positive terminal and the black wire to the negative terminal.

NOTE: Make sure the fence charger switch is turned to the OFF position. Connect the battery charger to the battery and plug the battery charger into the wall voltage of 110 or 220 volts so that the battery is being continuously charged. Make sure that the battery charger is “current limited” or of the type that can be continuously connected to your battery without overcharging the battery.

Now connect your Earth Ground System  and all your ground return wires together, and then make the connection to ground connection on the fence charger. Use a minimum size wire of 14 AWG or larger, in either solid copper or galvanized steel. Make the connections with appropriate connectors. A common cause of failure is a poor connection to the high voltage strands from the high voltage charger.

Make sure you have a good earth-to-ground network. Always use a minimum of two ground rods, three or more meters (10 feet) apart, and additional ground rods at least every 100 meters (300 feet). Do NOT connect the fence energizer ground to any household ground such as water pipes, well casings, etc. This could cause a dangerous condition if there’s a lightning strike on the fence strands.

If the monitor system used is also charged with detecting ground voltage, a separate ground network should be used for grounding the monitoring device.

Finally, make your high voltage connection to the fence using an appropriate connector with high tensile or spark plug wire, with an insulation rating capable of carrying the high voltage with a large enough safety factor.

When you run the high tensile wire to the fence charger make sure the high voltage wire is not laying on the ground, and is not running through water, and is not placed across sharp corners. Many installations use standard (14AWG solid) single strand wire fed through one or more thick wall plastic hoses.

Connect your fence monitor to your battery and connect the end of your high voltage charged loop to the high voltage terminal on the monitor, using the same high tensile wire that you used to connect the charger to the fence.

Connect the Earth Ground System to the ground terminal of the monitor, or if desired connect to a solid earth ground network used only by the monitor.

The fence monitor will continuously monitor the voltage on the fence. If an intruder cuts a wire the fence monitor will sound a siren alarm. On the Fence Hawk, a more sophisticated monitor,  the grass, weeds, or brush, when grown, partially shorts out the fence and lowers the high voltage. A separate warning alarm will be given to alert you that the fence should be checked and cleared.

We strongly recommend a separate battery to power the monitor and siren, bell, or whatever alarm notification is connected to the fence monitor. The small extra cost of a small 12-volt battery that will feed your monitor and devices raises the security rating of your system at least another notch higher on the security rating scale.

A high voltage fence charger/energizer with a voltmeter, that will also continuously monitor the voltage on the fence, is a super backup device. If a frond or foliage is laying across the high tensile wire, and partially shorting it out, the fence voltage will drop and will indicate on the voltmeter on the energizer.

We recommend that you check your fence at least once a week. Plant foliage, or branches or fronds laying across the high tensile wire might not reduce the voltage on the meter when dry, but foliage becomes a conductor when wet and might easily short out your system, completely reducing the fence voltage to almost zero when soaked from rain.
