INTRODUCTION
Thank you for choosing our product! NEMTEK Electric Fence Energizers are designed and
manufactured to provide many years of reliable use, if installed and maintained correctly. The
guidelines provided in this manual will assist you with the basic operation and maintenance of
your energizer.
Currently this energizer is designed and manufactured in South Africa for the South African and
international markets. More information on our products and general information are available
on our web site at: http://www.nemtek.com.
COMPANY PROFILE
The NEMTEK Group of Companies manufacture and distribute intelligent electronic agricultural
fencing systems, security and perimeter control systems and have been involved in the security
industry since 1990.
We have our own research and development team, designing and manufacturing a full range of
globally competitive electric fence energizers and related products.
NEMTEK is continually updating its products according to South African and international
standards in order to ensure the highest quality products and continuous customer satisfaction.
Electric fencing can be lethal. Avoid head contact with the fence. When installing
please take careful note of the options available for current limiting resistors, the
programmable output energy levels as well as the low-voltage operation of the
energizer.

Introduction & Company Profile

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
