The Agri
and Agri Solar
range of energizers should ideally be operated together with a
AGRI
Foreword
AGRI Solar
Nemtek key-chain remote to gain access to the many energizer settings and
information. The energizer will however operate as a conventional energizer without
the Nemtek remote.
When the energizer settings are changed, using the Nemtek key-chain remote, the
new settings will be retained even when the energizer is disconnected from a power
source for an extended period of time.
This energizer includes a theft deterrent feature. The energizer can be locked to a user
chosen PIN. This PIN is entered and stored within a Nemtek key-chain remote. When
this function is enabled, the energizer is prevented from operating until after a Nemtek
remote, containing the correct PIN, is presented to the energizer. Each time power is
removed and restored to the energizer, the Nemtek remote will need to be presented,
to activate the energizer.
The Agri and Agri Solar range of energizers incorporate our advanced and patented
fence voltage control system, referred to as Adaptive Power Technology or APT. What
this means is the fence energy is maintained at a higher level than would normally be
achievable using a conventional energizer on the same fence, when factors such as
poor or damaged insulators, wet insulators after a rain storm, or salt build up on
insulators (at the coast) prevent the fence from supporting a high voltage. A
conventional energizer will push all available energy through any significant arcing
present on the fence, reducing the fences effectiveness. This energizer, with APT
control active, will detect any significant arcing and attempt to operate the fence at a
voltage just below that at which the arcing occurs, thus maintaining higher energy
levels on the fence and improving the effectiveness of the fence. Nemtek is the
inventor and patent holder of this innovative technology

Operating without
AGRI Solar
Operating the energizer without a Nemtek remote is straightforward. Once the energizer is
connected to the fence, plug the black (-) battery clip into the energizer and clip the other
end of the lead onto the battery negative terminal. Then plug the red (+) battery clip into
the energizer and clip the other end of the lead onto the battery positive terminal. Agri Solar
units have dedicated solar power connectors. If the factory default settings have not been
altered, the energizer will begin operating at 8kV pulsing once per 1.5 seconds. The pulse
rate & warning light should flash once with each fence pulse.
If the pulse rate and warning light (ENERGIZER) changes colour from green to red the
energizer is working harder than 95% of its design capacity. The higher the fence voltage is
set, or the larger the fence, or more foliage touching the fence, the greater the energizer
effort required to energize the fence.
The power status indicator (BATTERY for solar and SUPPLY for mains versions) glows green
if the battery voltage is greater than 11.6V, glows red when the battery voltage falls below
10.5V and glows yellow when the battery voltage is between 10.5V and 11.6V. The
energizer will shutdown when the battery voltage falls below 10V.
Solar regulator status (SOLAR) is green when the battery is charging, unlit when the battery
is discharging and red when the battery is not connected.
As well as the Nemtek remote, a Nemtek tag is available which is used to toggle the
energizer active state (on/off). The Nemtek tag is supplied with the energizer
a key-chain remote

Using the Nemtek
AGRI Solar
The torch can be activated in two ways. By either holding down the button until the torch
activates, or by switching the remote on, navigating through the menu to the item TORCH,
and selecting that function by pressing the button again. With the torch activated, you
can increase brightness by pressing the button. To increase brightness quickly, press and
hold the button. Use the button to decrease brightness.
To activate the Nemtek key-chain remote menu, press the button firmly, and release it.
Don’t press it so long that the torch is activated. To preserve the remote’s batteries, the
button is designed such that very short presses or bumps of the button will not activate the
remote. Additionally, the remote will automatically switch of after 30s of inactivity.
Use the and buttons to navigate back and forth through the remote’s internal menu.
To select the displayed item, press the key briefly. Some items, such as PIN, require the
button to be pressed for an extended period, so as to prevent unintentional changes.
The user PIN is used in the security function of the energizer. To set the user PIN, long
press of the button while the item PIN is displayed. Step through the digits by repeatedly
pressing and releasing the button. The flashing cursor beneath the digit to be edited will
move one digit to the right with each press and release of the button. Increase or
decrease the value of a digit by pressing the or buttons. Once the desired PIN is set by
repeating this process for each digit in the PIN, commit the pin to the remote’s memory by
holding down the button until you are returned to the NEMTEK display. The PIN is stored
in the remote even when the batteries are removed, so the PIN need only be set once.
You need to remember or make a note of this PIN for later referral so that you can re-enter
this same PIN into a new remote, should your existing remote be lost or destroyed. If you
have locked an energizer using a remote, and no longer have access to that remote, and do
not know what PIN was programmed into the remote, then you will have to return with the
energizer to Nemtek or an authorized outlet for unlocking.
To turn the remote off, navigate back to the NEMTEK display and press the button.

Operating with a
key-chain remote
Operating the energizer with a Nemtek key-chain remote is the same as for operating the
energizer without a remote, except that, if the energizer has been locked, then at power on,
the Nemtek key-chain remote will have to be presented to the energizer before it begins
operating.
To present a remote to the energizer, perform these following steps;
• Turn the Nemtek key-chain remote on as discussed in the previous section.
• Be sure you have activated the menu and not the torch.
• Hold the remote such that the symbol near the top right of the remote is over the
Nemtek logo on the front of the energizer (see drawing on page 13).
• Keep the remote in place for a second or two, after which you should hear a short
beep from the energizer indicating successful completion of a transaction. If instead a
long beep is heard, then the energizer has been locked with a different pin to that
contained in the remote you are using. If no beep sound is heard, slowly move the
remote over the face of the energizer in the vicinity of the Nemtek logo.
• On hearing the beep, you can move the remote away from the energizer and a new
energizer menu will appear on the display of the remote, through which you can start
navigating.

Additional information on menu items
Energizer effort or capacity used is useful in determining if your fence condition has changed
since installation. It can also be used to indicate that the energizer is unable to drive the
fence load. To use as a fence condition change indicator, set the WARN AT value above that
of the reported EFFORT value. When the loading on the fence increases and the energizer
starts to work harder, the high intensity warning light will begin to flash and will be seen from
a distance. To use as an energizer maximum capacity reached warning, set the WARN AT
value to 95%. When the high intensity warning light begins to double flash, you will know the
voltage on the fence is about to, or has already, dropped below the set voltage.
V MIN, is the lowest fence voltage recorded since the energizer was last read using a remote.
% MAX, is the maximum energizer effort or capacity used since the energizer was last read
using a remote.
As examples of use for this information, consider the following scenario;
If the fence is being shorted out by faulty insulators during a patch of rain this would be
recorded and reported the next time the remote is presented.
If the fence is being deliberately shorted in order to gain access to your animals at night, then
this would be recorder as a % MAX value of 100% and a low V MIN value.
As this information is reset each time the remote is presented to the energizer, be sure to
remove the remote after the first beep else the recorded values will be lost.
Notes
*Only energizer settings can be altered. Information items such as supply voltage and
energizer effort cannot be altered as they are presented as information only.

AGRI
Installation notes
AGRI Solar
• Keep the fence separate from the battery wiring.
• Do not try and modify the energizer. Any unauthorized modifications will null and void
the warranty and possibly render the unit illegal.
• Use HT (high voltage) wire between the fence and energizer, including the earth wire.
Never run these wires in the same conduit or through the same hole as the low
voltage wiring.
• Always use ferrules or line clamps to connect two high voltage wires together. Avoid
using dissimilar materials for connections, like copper on steel.
• The fence must be earthed properly with three earth electrodes close to the
energizer. The distance between the fence earth electrode and any other earth
systems shall not be less than 2m for a security fence installation (typically a
suburban property installation), and 10m for an agricultural fence installation
(typically a rural property installation).
• Refer to the applicable laws concerning the installation of electric fences in your area.

General requirements for electric fences
AGRI
Appendix
AGRI Solar
Electric fences shall be installed and operated so that they cause no electrical hazard to persons, animals or
their surroundings.
Electric fence constructions which are likely to lead to the entanglement of animals or persons shall be
avoided.
An electric fence shall not be supplied from two different energizers or from independent fence circuits of the
same energizer.
For any two different electric fences, each supplied from a different energizer with independent timing, the
distance between the wires of the two electric fences shall be at least 2.5m. If this gap is to be closed, this
shall be affected by means of electrically nonconductive material or an isolated metal barrier.
Barbed wire or razor wire shall not be electrified by an energizer.
Electric fences and their ancillary equipment shall be installed, operated and maintained in a manner that
minimizes danger to persons, and reduces the risk of persons receiving an electric shock unless they attempt
to penetrate the physical barrier, or are in a secure area without authority. Exposed conductive parts of the
physical barrier shall be effectively earthed.
A spacing of 2.5m shall be maintained between non insulated electric fence conductors or non insulated
connecting leads supplied from different energizers. This spacing may be less where conductors or
connecting leads are covered by insulating sleeving, or consist of insulated cables, rated to at least 10kV.
This requirement need not apply where the separately energized conductors are separated by a physical
barrier, which does not have any openings greater than 50mm.
A vertical separation of not less than 2m shall be maintained between pulsed conductors fed from different
energizers.
Ensure that all ancillary equipment connected to the electric fence circuit provides a degree of isolation
between the fence circuit and the supply mains equivalent to that provided by the energizer. Protection from
the weather shall be provided to the ancillary equipment unless this equipment is certified by the
manufacturer as being suitable for use outdoors, and is of a type with a minimum degree of protection IPx4.
Connecting leads that are run inside buildings shall be effectively insulated from the earthed structural parts
of the building. This may be achieved by using insulated high voltage cable.
Connecting leads that are run underground shall be run in a conduit of insulating material or else insulated
high voltage cable shall be used. Care shall be taken to avoid damage to the connecting leads due to
external factors.
Connecting leads shall not be installed in the same conduit as the mains supply wiring, communication cables
or data cables.
18
AGRI
Appendix
AGRI Solar
Connecting leads and electric fence wires shall not cross above overhead power or communication lines.
Any part of an electric fence which is installed along a public road or pathway shall be identified at frequent
intervals by prominently placed warning signs securely fastened to the fence posts or firmly clamped to the
fence wires. The size of the warning signs shall be at least 100mm x 200mm. The background colour of both
sides of the warning plate shall be yellow. The inscription on the plate shall be in black.
The warning sign shall typically appear as depicted in the figure below. The inscription shall be indelible,
inscribed on both sides of the warning plate, and have a height of at least 25mm.
Warning signs shall be placed at;
• each gate
• each access point
• intervals not exceeding 10m
• adjacent to each sign relating to chemical hazards for the information of emergency services.
Gates in electric fences shall be capable of being opened without the person receiving an electric shock.
Mains supply wiring shall not be installed in the same conduit as signaling leads associated with the electric
fence installation.
Where an electric fence passes below bare power line conductors, the highest metallic element shall be
effectively earthed for a distance of not less than 5m on either side of the crossing point.
Crossings with overhead power lines shall be avoided wherever possible. If such a crossing cannot be
avoided, it shall be made underneath the power line and as nearly as possible at right angles to it.
If connecting leads and electric fence wires are installed near an overhead power line, the clearances shall
not be less than those shown in the table below.
Power Line Voltage Clearance
Equal or less than 1kV 3 meter
Greater than 1kV, but equal or less than 33kV 4 meter
Greater than 33kV 8 meter
If connecting leads and electric fence wires are installed near an overhead power line, their height above the
ground shall not exceed 3m.
This height applies either side of the orthogonal projection of the outermost conductors of the power line on
the ground surface, for a distance of:
• 2m for power lines operating at a nominal voltage not exceeding 1kV
• 15m for power lines operating at a nominal voltage exceeding 1kV
