Counter Assault Pentagon User Manual

Lightweight Electric Fence System

Thank you for purchasing the Pentagon™ Electric Fence System. This is the first commercially

available electric mesh fence kit that meets or exceeds the guidelines published in the USDA
Forest Service Recreation Tech Tips (0723 -2305MTDC) in March 2007. Please read the following
instructions carefully to become acquainted with the features, assembly, and safe operability of the
Pentagon™ Electric Fence. This high performance device must be installed and operated properly
in order to achieve the best possible results.

Counter Assault has assembled the highest quality components to provide the optimum perform­ance, battery-operated, lightweight electric mesh fence system available. An electric fencing
system is comprised of three main components: (1) energizer, (2) transmission lines, in this case,
the mesh poly wire which includes the built in fence posts with insulators, and (3) the grounding
path to the earth.
How Does Power Fencing Work? A pulsed electric current is sent along the fence wire from a
properly grounded energizer. When the bear touches the fence it completes the circuit between
the fence and the ground and receives a short, sharp but safe shock. The shock is sufficiently
memorable that the bear should never forget.

The energizer is the heart of the fencing system and Counter Assault has selected the Speedrite
AN90. The portable AN90 is operated by four "D" size batteries, which produces 35-45 pulses per
minute and delivers 8000-9000 volts, which equates to 0.12 joule output rating, with .16 joules of
stored energy, and can last for 30-40 days of continual operation.

Another unique component to this electrical system is the mesh fence. Tests have shown that the
mesh configuration with alternating hot (energized) and ground wires is recommended for bears.
The mesh containing the semi-rigid stays (the larger vertical poly wire) keep the mesh from
drooping, which could allow the hot wires to short out against the ground wires. Additionally, we
have incorporated ¾ inch sturdy double prong posts to keep the fence erect and reduce sagging.
The mesh fence is also quicker and easier to erect and disassemble.

Installation and Assembly Directions

Choose a spot to install the fence where the ground is flat, where no trees or brush will hang over the
fence, and where the fence does not block an established game trail. Unroll the fence and grab the
posts, allowing the loops of mesh to droop between the posts.

To install the fence:

1. Select the spot for the center of the enclosure, each post will be approximately 9 feet from that
center point.

2. Hold the posts and allow the fence mesh to drop.

3. Push the end posts into the ground at your starting point. Do not hammer the posts into the ground.

4. In a pentagon shape, insert each of the remaining poles into the ground to delineate the five sides of
the fence. At the last post, push the post into the ground next to the first post; completing the pentagon
shape. FIGURE 1

5. Use one of the Velcro straps and loop the strap end through the insert hole and strap this to the top of
end post #1. Then take the loose end and wrap around end post #6 to connect the two. Posts #1 and #6
are basically the "opening and closing" of the fence enclosure. The Velcro strap can be unwrapped and
wrapped repeatedly while erecting the fence. FIGURE 1

6. Reposition the individual posts (#2-#5) until you are satisfied with the fence's tension and shape.

7. NOTE: Make sure that the orange wires are on the outside of the post.

8. Place the Energizer on the ground next to the posts just outside the fence. Drive the ground rod into
the ground near the energizer.

9. Clip electrical wires together (both top and bottom) with the metal crimped tabs on the mesh fence
near the end posts. FIGURE 1

10. Turn LED lights on by twisting tight. Then clip the lights to the mesh by any two posts. The lights
will initially flash red, white and blue, then only red, indicating low batteries. Replace with LR41
button batteries.

11. To Energize the Bear Fence connect the Yellow (hot) wire to the prong on the top of the energizer
and clip to the Metal Fence Connector on the mesh fence. Connect the Green wire to the Ground Rod.

FIGURE 2

NOTE: If you do not connect the Yellow (hot) wire from the energizer to the proper metal clips on the
fence and the GREEN (ground) wire to the ground rod, the energizer will not operate properly.

12. If using an external 6/12 volt power source, you will need to use the optional RED & BLACK
power leads as shown in the energizer instructions. Connect RED lead to the + prong on the bottom of
the energizer. Connect the BLACK lead to the - prong on the bottom of the energizer. Connect the Red
to the positive terminal on the battery and connect the BLACK to the negative terminal on the battery,
then refer to # 11 to connect the energizer to the fence.

13. If the soil is very dry, pour water over the ground rod to provide a good earth ground.
