INTRODUCTION

Introduction & Disclaimer

3

The WIZORD 2 is a battery (12V 7AH nominal) operated energizer suitable for connection to

mains (220-240Vac, 50-60Hz).

The batteries to be used are rechargeable lead-acid batteries. Non-rechargeable batteries must

not be used. The lead-acid batteries require venting and it is imperative that the energizer be

situated in a well-ventilated area.

A new fully charged battery will typically provide in excess of 24 hours backup. Backup time will

vary with fence condition though.

Electric fencing can be lethal. Please avoid entanglement\entrapment hazards (See APPENDIX

at the end of this manual) and warn the user to avoid head contact with the fence.

NEMTEK Holdings (Pty) Ltd or any of its subsidiary companies does not guarantee that the

operation of the product will be uninterrupted or totally error free.

Energizer specifications may be altered without prior notification.

The installer is referred to the definitions and general requirements in the Appendix.

The installer must take into consideration the applicable municipal laws concerning the

installation of electric fences. General guidelines are available, or refer to the website:

http://www.nemtek.com. International standards can be viewed at http://www.iec.ch and

South African standards on http://www.sabs.co.za.

removing the two cap screws. Unplug the

battery terminals if connected.

STEP 2: Remove screws and battery bracket

STEP 3: Remove battery

*Dispose of old battery according to legal

requirements. Do not replace with a non-

rechargeable battery!

STEP 4: Use a drilling template and drill 4 x

8mm holes in the wall for mounting the unit.

Insert the plastic sleeve of the nail in anchor

into the wall then hammer the screw in with a

screwdriver and hammer.

NB: Always insert the plastic sleeve from

the inside of the box.

STEP 5: Insert battery with the positive

terminal to the top.

STEP 6: Place the battery bracket back

(with plastic offsets at the top) and fasten

the screws into place.

STEP 7: Connect battery wires. Close the lid

by hooking the top of the lid in first and then

fasten the bottom down with the two cap

screws. Apply mains power to the unit.

Note: Energizer to be mounted vertically against a

flat surface, in a well ventilated area.

Avoid prolonged exposure to direct sunlight.

• Electric Fence:

A barrier which includes one or more electric conductors, insulated from earth, to
which electric pulses are applied by an energizer

• Connecting Lead:

An electric conductor, used to connect the energizer to the electric fence or the
earth electrode

• Electric Security Fence:

barrier electrically isolated from the electric fence

• 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

• Secure Area:

An area where a person is not separated from pulse conductors below 1,5m by a
physical barrier

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, as entrapment can be lethal.

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.

Any part of an electric fence which is installed along a public road or pathway shall be

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 security fences shall be capable of being opened without the person
receiving an electric shock.

The energizer earth electrode shall penetrate the ground to a depth of at least 1m. The
distance between any electric security fence earth electrode and other earth systems shall
not be less than 2m.

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.

Connecting leads and electric fence wires shall not cross above overhead power or
communication lines.

Mains supply wiring shall not be installed in the same conduit as signaling leads associated
with the electric security fence installation.

Crossings with overhead power lines shall be avoided wherever possible. If such a crossing

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.

Where an electric security 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.

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 1 000 Volts

• 15m for power lines operating at a nominal voltage exceeding 1 000 Volts

Electric security 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

secure area without authority. Exposed conductive parts of the physical barrier shall be
effectively earthed.

A spacing of 2.5 m shall be maintained between uninsulated electric fence conductors or
uninsulated 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 security fence circuit provides
a degree of isolation between the fence circuit and the supply mains equivalent to that

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.

• Keep the wires to the fence separate from the keypad, gate, siren, strobe and

mains wiring.

• Never use the energizer battery to power a radio alarm transmitter or alarm panel.

• Always test the fence after installation for correct short and open-circuit alarming at
