Present the Nemtek Tag (Supplied with the energizer)
Operating the energizer is straightforward. Once the energizer is turned on,
it will pulse the fence once per 1.5 seconds. The pulse rate & power
indicator (ENERGIZER) should flash once with each fence pulse.
The (ENERGIZER) indicator flashes green to indicate high power mode or
red to indicate low power mode. The power status indicator (BATTERY)
glows green if the battery is above 50% capacity, glows yellow when the
battery capacity falls below 50% and glows red when the battery capacity is
below 5%.
The energizer disconnects the battery when the battery becomes
discharged, and will reconnect the battery automatically when solar power is
available again. 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.
If the energizer is not actively pulsing, it will automatically disconnect the
battery after a short period of time and can be stored away in this state. The
battery will automatically get reconnected when solar power is available or
the Nemtek tag is presented to the energizer.

Using the Nemtek Tag
11
The Nemtek tag is used to toggle the energizer on/off or to toggle the energizer between
the low or high power operating state. Hold the tag over the Nemtek logo on the front of
the energizer and the energizer will emit a short beep upon detecting the tag.
To toggle the energizer on or off, remove the tag after this first beep and the energizer
will emit a further beep when turning on, or a double beep when turning off.
To toggle the low/high power operating state of the energizer, keep presenting the tag
after the initial detection beep. After about 1.5 second has passed, a long beep will be
emitted. The tone of this long beep will be low if the energizer has switched to low
power mode or high if the energizer has switched to high power mode. Once active, the
(ENERGIZER) LED will pulse green if the energizer is in high power mode or red if the
energizer is in low power mode.
In order to extend the battery operating life of the energizer, The BATTERY and SOLAR
indicators will only remain active for 1 minute each time the Nemtek Tag is presented to
the energizer. The indicators do however remain active, should solar power be present
and the energizer is not actively pulsing the fence.
Tag

• 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.

electrode
• Electric animal fence:
An electric fence used to contain animals within or exclude animals from a particular area
• Public Access Area:
Any area where persons are protected from inadvertent contact with pulsed conductors by
a physical barrier
• Pulsed Conductors:
Conductors which are subjected to high voltage pulses by the energizer
• Earth electrode:

General requirements for electric fences
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.
AGRI Solar
Appendix
14

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
