Instructions/Diagrams:

Common Uses
A 110v AC or 12v DC electric fence energizer used mostly to keep out deer, raccoons and rabbits from garden/orchard areas. It is also used to keep in poultry, cattle, sheep, goats, horses, and guard dogs. Effective at protecting against coyotes, stray dogs, bear and fox.

Specs
IntelliShock 20
  • Peak output: 2 joule
  • Pulses per minute: 38
  • 110 AC draw: 3.3 watt per hour
  • 12v DC draw: 32-196 mA/hr. With this energizer a 12v 100 ampere hour, deep cycle battery will last approximately 13 days* on a weedy fence or 78 days* on a clean fence. *Assumes being drawn down to 40% between recharges.
  • Includes: 12v battery leads, 110v adapter and wiring harness.
  • Impedance type: low
  • Should power 2.5 miles of 3 strand cattle fence, 1 mile of a 6 strand sheep fence, 16 of the 164' sheep/goat nets and 6-8 of the 164' poultry nets. All distances are dependent on amount of grass/weed load on the fence.

Miscellaneous—see under Accessories Tab above

  • Requires 6' of ground rod in the ground (available under accessories tab above).
  • Use a 20-40 watt solar panel.
  • Can be used as a solar energizer.
  • Batteries are sold separately.

Benefits
Versatile. Can be used as a plug-in energizer or as a battery energizer. Adapts from one style to the other in a few seconds. Can be moved around easily. Low cost.

Installation
To use the energizer as a plug-in unit:
The energizer can be mounted either inside or outside of a building, but not where there is risk of fire. The energizer must be mounted vertically. Protect the energizer from direct rainfall.
  1. Connect an insulated cable (stripped back 1 - 2" on ends) to the fence terminal on energizer, run the cable to the fence line and connect, or use the positive part of the wiring harness.
  2. Then run a second length of cable from the ground terminal (with ends stripped again) on the energizer to the ground rod(s), or use the negative part of the wiring harness.
  3. Secure to ground rod(s) with a clamp.
  4. Plug the energizer directly into an outlet and test fence. Do not use an extension cord as it may cause a decrease in voltage and expose the unit to the elements.

To use the energizer as a battery unit:
  1. Attach wiring harness to energizer.
  2. Attach the bare end of the wire with the red clip to the fence terminal of the energizer. Attach the red alligator clip to the fence.
  3. Attach the bare end of the wire with the black clip to the ground terminal of the energizer. Attach black alligator clip to the ground rod(s).
  4. Connect the energizer to the battery.
  5. Insert battery adapter into the energizer. Attach red alligator clip from the adapter to the red “+” terminal of the battery.
  6. Attach black alligator clip from the adapter to the black “–” terminal of the battery.

Unit indicator light should flash and a tic-tac sound will be heard. If the indicator light doesn't flash, then the unit/battery should be checked.

Precautions
Make sure the power is turned off before working on the fence or the energizer.

To Reduce Risk & Liability

  • Never place your head or upper spine near an electrified wire. Accidental head or neck contact can occur when pushing a voltage probe into the soil. Be careful when doing so to avoid head-to-wire contact!
  • Never attempt to step over or climb through an energized fence of any kind.
  • Never encourage anyone to touch an electric fence.

Troubleshooting
To determine if the fault is with the fence or the energizer...
  1. To check—first turn off the energizer.
  2. Then disconnect the wires going to the fence and ground rod system.
  3. Turn the energizer back on.
  4. Then measure the voltage on the energizer between the 2 terminals (fence and earth) with a digital fence voltmeter or other fence testing device. Touch one end to “–” earth terminal and the other end to “+” fence terminal.
  5. If the tester reads under 4000v, the energizer (or possibly the battery if it’s a battery/solar energizer) is the problem.
  6. If the tester reads more than 4000 volts, the energizer is working properly and the fence is the problem.

    7. Most energizers put out between 5000v and 8000v when there is no load (i.e. no fence hooked up).

If the energizer is faulty and you're using it as a 110 volt plug-in unit...
  1. Check that the 110v outlet is "live" by using a plug-in drill or test light.
  2. If the test light works and the energizer does not, call Premier.

If the energizer is faulty and you are using it as a battery unit you need to learn if the battery or the energizer is the problem…

  1. If it's a 12 volt energizer carry the unit to a nearby vehicle and attach the input cords carefully to the vehicle's battery.
  2. If the energizer now works, then your fencer's battery needs to be recharged or replaced.
  3. If the energizer does not work, then you should call Premier re. repairs.

If the fence is at fault, then you must find the fault(s) and fix them. Here's how to start this process: If you have a Fault Finder you can simply touch the fence with the Fault Finder at various points along the electric fence(s). The Fault Finder will tell you at each point which direction to go in to locate the problem. Move in that direction testing as you go and you will arrive at the problem.

If you lack a Fault Finder…

  1. Walk or drive along the fence looking for any point in which the energized wires touch the soil, a steel post or a steel wire. On HT wire fences, check the wires at braces to see if they are touching a hot wire. On netting, look for a hot wire touching the metal stake at the bottom of the plastic posts. Also look for damaged insulators.
  2. If the fence can be separated into several parts (by switches or by disconnecting parts of it), you can locate the problem by beginning at the far end and then progressively turn off or disconnect the sections of fence. When the voltage on the remaining fence rises sharply, you've located the section(s) that's causing the problems.
  3. The alternative to (2.) is to begin at the fencer and progressively turn on sections of the fence. When the voltage suddenly drops you can assume that the problem is in the section most recently connected.

Warranty
2-year warranty for energizers and solar panels cover lightning damage and defective parts or workmanship. Should an energizer fail, we will replace the unit, bill you for the cost to do so, then reimburse you for warranted expenses after we have examined the failed unit. Misuse and flood damage are not covered.

IntelliShock 20 Energizer
★ ★ ★ ★ ★

I wanted to build my own mobile fence charger and in doing so I wanted to be able to upgrade certain aspects and future proof certain aspects. And I can honestly say I am glad I decided to future proof with this! Very reliable, very energy efficient as I am using only solar and batteries to operate it and sometimes I don’t get much sun in some areas I have my charge box. So this unit drawing such little power is very reassuring to me to know I will always have power to the fence.

Needed a unit that could be battery powered for a garden fence, electric netting. This seemed to be the most charger for the money, arrived quickly, was easy to set up. Really neat that it can be used either 12v or 120v, I just have to remember where I put the AC converter.

I bought this energizer about 6 months ago and it has worked great on A/C power. Went to use it on D/C power and one of the clamps that clamp to the battery was broke. Contacted Premier 1 and they sent out a replacement quickly. Thank you Premier 1 for the great customer service. Very Happy with my purchase.

This energizer is built like a TANK. The energizer has been through the elements and keeps on ticking. This unit maintains a excellent voltage over small or large areas. We use ours to keep in sheep, chickens and cows (2500 ft) and is simply an excellent unit. Be sure to have at least 3-6' of ground rod, a longer ground rod 6-8' is better but 3-6' works great too. This is the only energizer I will buy going forward.
