DRUID Installer Notes
INSTALLATION NOTES:
1) Use high voltage insulation 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.
2) Always use ferrules or line clamps to connect two high voltage
wires together. Avoid using different types of material for connections
like copper on steel.
3) The fence must be earthed properly with at least one earth
electrode as close as possible to the energizer. The distance between
the fence earth electrode and other earth systems shall be not less
than 10m.
4) Do not try to modify the unit. Any unauthorized modifications will
null and void the warranty and possibly render the unit illegal.
5) To connect the energizer to a radio alarm transmitter or alarm panel
use an isolation relay between the siren output and the panel.
Never use the energizer battery to power a radio alarm transmitter or
alarm panel (see 4).
6) The siren output can maximum be loaded with a 15W siren (1.25
Amps).
7) The strobe output can maximum be loaded with a strobe which will
draw less than 0.5 Amps.
8) The wires to the gate input can be up to 100m long but must not run
in parallel with the fence wires. The gate input must be connected to a
normally closed contact when the gate is closed.
9) Keep the high voltage wires to the fence separate from the mains,
gate, siren and strobe wiring.
10)When replacing the lid of the energizer hook the top in first while
holding it at an angle and then push it closed at the bottom. Fasten
the lid down with the two cap screws.
11)Always test the fence alarm for a short and open-circuit after
installation at the furthest point on the fence.
12)Do not use the energizer with Non-rechargeable batteries and any
lead-acid batteries must be placed in a well-ventilated area during
charging.
13)The unit contains a sealed lead-acid battery that will vent to the
atmosphere under certain conditions. For this reason it is imperative
that the energizer be installed in a well ventilated area.
14)Refer to the applicable laws concerning the installation of electric
fences.

DRUID Appendix A
BASIC DEFINITIONS:
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: a fence used for security purposes which comprises
an electric fence and a physical 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.
GENERAL REQUIREMENTS FOR ELECTRIC SECURITY 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
independently timed, 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 effected
by means of electrically non-conductive 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 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 black . The warning sign shall typically appear as depicted
in Figure x. The inscription shall be indelible, inscribed on both sides of the
warning plate and have a height of at least 25 mm.

DRUID
Appendix A Cont’d
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 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 Table 1.
Power Line Voltage (V) Clearance(m)
Equal or less than 1 000 3
>1 000 and equal or less than 33 0004
>33 000 8
Table 1

12
DRUID Appendix A Cont’d
If connecting leads and electric fence wires are installed near an overhead
power line, their height above the ground shall not exceed 3m.
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 000V
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 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 2.5 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 2.5m 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 provided by the energizer. Protection from the
weather shall be provided from 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.
