1. YOUR NEW VOSS.farming impuls
Thank you for choosing the VOSS.farming impuls duo. You have purchased a top-quality energiser for building a reliable and secure electric fence. Please read these opera ting instructions thoroughly before using the VOSS.farming impuls duo. This manual
contains important safety instructions, tips and information.
The VOSS.farming impuls duo can be operated via a 12V batter y or via a 230V mains adapter. The energiser constantly checks the voltage on the fence and adjusts the output
automatically. This makes it par ticularly energ y ecient and prolongs the battery life
considerably.
LED lights (3) and (4) on the front of the unit indicate whether the device is in operation,
measure voltage of the fence and also indicate possible faults on the fence.
Mains adapter connection / 12 V batter y connection (1 & 2)
Mains adapters and 12V connec tion cables are connected via sockets on the back of
the device.

• Blinking - 12 V battery operation
• Continuous - 230 V mains operation
• LED blue - power output at 100 %
• LED purple – power output at 50 %
• LED red – low bat tery
When the batter y voltage drops below 11.8 V, the energiser emits a beep and st arts
operating in energ y-saving mode. When the bat tery voltage drops below 11.6 V, the
energizer switches o automatically. The deep discharge protection keeps the battery
from becoming damaged.

2. HOW DOES AN ELEC TRIC FENCE WORK ?
The VOSS.farming impuls duo is the heart of your fence. It generates electrical pulses
at regular intervals. The unit is connected to the ground (“grounding”) and the conducting material of your fence. If a connection is made between the ground and the
fence (shor t circuit) – such as by contact with animals – then the circuit is closed.
The elec tric shock felt by the animal is completely safe, yet ver y unpleasant, and
scares the animal away.
The elec trical circuit is completed
through the ground. It is not necessary to create a closed fence system.
The fence can end at any point.

3. INSTALLATION AND CONNECTION:
Install the energiser vertically on a wall. You can use the included screws for this. A
practical clip-mount bracket (item no.: 41150) is also available as a separate accessory.
Two clips are required for installing the VOSS.farming impuls duo series. This lets you
install the energiser on a conventional DIN rail.
The VOSS.farming impuls duo can withstand all weather conditions such as rain, splash
water, sunshine, high temperatures and frost. However, we recommend that you place
the VOSS.farming impuls duo somewhere that oers protection against the weather,
such as a house wall, (roofed) shelter, stable, box or in an enclosed space such as a
garage, summer house, carport, shed or workshop.
TIP: Before you connect the VOSS.farming impuls duo to your fence, you can test the
energiser. Unscrew the two terminal nuts (6 and 7) and connect the device to a power
source. The control LED (3) will light up, depending on the selected operational mode,
and the LED bar (4) will ash simultaneously with each released impulse.
For further inspection, you require a screwdriver long enough to create a connection
between the terminals. Hold the screwdriver by the insulated handle. !!! Holding the
screwdriver by the shaft or by the damaged or non-insulated handle will result in a
shock. !!! Now place the shaft on one of the terminals and start pushing it in the direction of the other terminal. Just before the tip of the screwdriver touches the second
terminal, you should see a small, harmless spark.
If the control LED (3) or the LED bar (4) do not light up and/or there is no spark, then
check the power supply rst: connection to mains or batter y voltage. If there is no fault
here, the device should be checked by a specialist.
NOTE: A normal electrical voltmeter is not suitable for checking the voltage! Special
fence testers exis t for this purpose!
If your energiser is working properly, turn it o, unplug it, then proceed to connect your
fence system. Connect the ground connection (6, ground symbol, black terminal nut)
with your grounding post. We recommend using cables with M8 connection eyelets.
The grounding posts should be at least 75 cm long. The bet ter the grounding, the more
eective the electrical pulse will be. Connect the fence connection (7, lightning symbol,
red connec tion nut) to the fence using a fence connection cable. When assembling the
ground and fence connec tions, make sure to tighten the connection nuts by hand as
much as possible.
NOTE: To avoid lightning damage, we recommend installing a residual current device
(A) and lightning protection equipment (B), such as item numbers 48015 and 44755.
4. GROUNDING:
It is extremely important that your electric fence is properly grounded! This is essential
for the proper functioning of your energiser and to ensure maximum performance.
The grounding should be installed in a damp area with veget ation. Use galvanised
metal posts for the grounding posts. They must have a minimum length of 75 cm
(such as item no. 44219). Dry soil and long fences require additional grounding
posts at intervals of about 2–3 m to improve the connection with the ground.
We recommend using the cable with item no. 33615 for connec ting the grounding
posts. With optimal grounding, the VOSS.farming impuls duo can operate at its
maximum capacit y and ensure your fence provides the best possible security.
TIP: Where soil conditions are poor with low conductivity, we recommend using an
additional 2 or 3 grounding posts spaced about 2–3 m apart. If the soil is very dry or
stony, this will reduce its conductivity.
DE UK FR IT NL SE

A
Page 6
NOTE: Please choose a suitable location for your grounding system.
Your grounding s ystem must be:
• at least 10 m away from other grounding systems, such as ground connections of
homes, telephone or power lines.
• away from animals or pathways as animals or people may damage the grounding.
• accessible to you at any time for maintenance purposes.
If you run any connection cables through the inside of buildings, you must always use
insulated high-voltage cables.
5. THE IDEAL FENCE
Regardless of the types of conducting material used in your fence, there are a few
things to keep in mind in order to ensure good conductivity.
• Keep your elec tric fence system free from vegetation. Do not run your fence through
hedges and avoid having any branches or bushes complete the circuit.
This will reduce the voltage on your fence and the shock strength of the electrical pulse
may no longer be powerful enough.
• Ensure that the conducting material in your fence does not touch the ground,
e.g. by sag ging.
• Only use fence posts with insulators so as to insulate the conducting material from
the post and the ground. This will prevent any loss of voltage and ensure the desired
current ows through the conduc ting material of the fence.
Suitable accessories are available for using metal posts and industrial fences.
NOTE: It is a legal requirement to place warning signs on the fence in publicly accessible
areas, such as item no. 44735.
6. INITIAL SETUP:
NOTE: The following steps will help you activate the energiser. Your fence will
then be live. Make sure that there are no people or animals near the fence.
When the energiser is connected to the fence it constantly checks for faults. If the LED
bar (4) is red, there is a fault on the fence. Meaning your fence security is compromised.
Check your fence for faults.

7.MAINTENANCE AND CLEANING
Always turn o the VOSS.farming impuls duo and unplug it from the mains when
performing maintenance and cleaning work. The unit does not require regular maintenance, but you should inspect it visually on a regular basis. Check all cables and lines
for damage. Contact a specialist immediately to replace any broken par ts or cables. Do
not operate the energiser if there is any damage. Keep the energiser clean by wiping it
with a slightly damp cloth.
8. SAFE TY TIPS
Carefully read and observe the following before using the energiser:
This device may not be used by persons (including children) with physical, sensory or
mental impairments. Further, it may not be used by persons without sucient experience and specialist knowledge unless supervised or under guidance by another person
who is responsible for their safety. Children must always be super vised to ensure that
they do not play with the device. Electric fences must be installed and operated such
that there is no danger to people, animals and their surroundings.
Observe the following to ensure safe operation:
• Only use weaker energisers or outputs with limited pulse energ y (1 joule) in areas
where unsupervised children may be present and on electric fences with alternating
polarit y (positive/negative fences).
NOTE: Do not touch elec tric fence wires! Do not climb over, through or under fences
with several wires.
• Avoid using electric fences with alternating polarity in places where people may be
able to get between t wo wires of diering polarit y. If you must use such a fence,
then use a weaker energiser (e.g. with a 1 joule limit) – even with non-electried,
grounded wire.
• Provide people with access through the fence to public paths using insulated gates,
gate handles or insulated crossing points (stiles) at all points where access is intended.
Always use a gate or access point that is specically intended for that purpose.
Access points along public paths and any other place where there are people
should be tted with warning signs about every 100 m.
• Keep a minimum distance of 2.5 m between the electric fence and grounded,
metallic objects (such as water pipes and troughs), especially in areas where people
may be present.
• If there is a danger of ooding around the electric fence, stop using the energiser.
• If the pulse interval is less than 1 second, shut down the energiser immediately and
have it repaired if necessary. A pulse inter val of over 1.6 seconds means that the
energiser is no longer providing sucient security and requires inspection.
This device meets the requirements of EC directive 2004/108/EC “Electromagnetic
Compatibility ” (CE mark) and European safety standard EN 60335-2-76 (Electric Fence
Energisers).
Prevent misuse of the energiser by:
• Paying attention to markings on the device
• Securing it against unauthorised access (such as anti-theft protection, child
protection) if necessary in the installed location.
• Special use of electric fences in zoos or wildlife enclosures: Installation of such
systems may only be carried out by qualied electricians. A non-electric fence
must be present to separate visitors from the electric fence.
• If the mains connection lines to the energiser are damaged, then these must be
replaced by the manufacturer, the manufacturer’s customer services or another
similarly qualied person in order to avoid injury. Ser vicing and repairs may only
be carried out by authorised specialists! Only replacement parts authorised by
the manufacturer may be used.
OPERATING PRINCIPLE AND LIMITS OF ELECTRIC FENCES FOR ANIMALS
An electric fence consists of an energiser and an insulated fence. The energiser
supplies the fence with short electrical pulses. The electric fence presents a “physical”
and “psychological” barrier to animals. The short high-voltage pulses are very
unpleasant and animals will quickly learn to respect the electric fence.
A properly installed electric fence can provide a high level of safety and has many
advantages compared to a purely mechanical fence. As a psychological barrier, the
electric shock discourages animals from trying to get over the fence. Less work and
DE UK FR IT NL SE
Page 8
fewer materials are required, alterations are easily made, it is suitable for a ver y wide
range of animals and oers a great deal of protection against injury.
OPERATING PRINCIPLE OF THE ELECTRIC FENCE ENERGISER
The elec tric fence energiser emits an electrical pulse through the fence about once
every second. The pulse gives the animal a short, sharp, yet harmless shock. This is in
no way dangerous for the animal, but is enough that it will remember to avoid the fence
in future.
PRACTICAL TIPS
Check regulations for your local area before building a fence. You may require permission to do so. Regularly check the energiser to ensure that it is still functioning properly
by looking at the ashing indicator LED. Check the fence system regularly. Remove
any fallen branches, weeds or bushes as these may cause a short circuit and reduce
the eec tiveness of the fence. All animals will need time to learn to respect the fence.
Training may take several days and you may need to make some small adjustments to
the fence.
Animals that can jump may be dicult to fence in. You may need to increase the height
of the fence in order to ensure maximum safety. Make sure to use high-quality insulators. Cheap or cracked insulators and plastic tubes are not recommended as these can
cause short circuits.
Use connec ting bolts for all steel wire connections to ensure a good circuit is made.
To ensure correct functionalit y of the electric fence, ground the energiser using
grounding posts made of galvanised metal. Use double-insulated cable inside buildings, under driveways and in places where any galvanised wires lying on the ground
may become corroded. Never use household electrical cables as these are designed
to carry 600 volts at most and a loss of current may occur.
ELECTRIC FENCE REQUIREMENTS
Electric fences and associated equipment must be construc ted, operated and maintained such that there is no danger to people, animals and their surroundings. Elec tric
fences in which people or animals can get caught must be avoided. An electric fence
may not be supplied by two separate energisers or by independent fence circuit s from
the same energiser.
Where there are two separate electric fences, each supplied by a separate energiser,
the distance between the wires of the two fences must be at least 2.5 m. If this gap
between the fences must be closed o, then this must be done using non-conducting
materials or an insulated metal barrier. Barbed wire or sharp-edged wire may not be
electried by an energiser.
Observe the manufacturer’s recommendations for grounding the energiser.
A distance of at least 10 m must be kept bet ween the grounding electrode for the energiser and any other components connected to grounding s ystems (such as the ground
connections for power supply s ystems or telecommunications systems). Connecting
cables that run through buildings must be eectively isolated from grounded parts of
the building. This can be achieved using insulated high-voltage cables.
If connec tion cables and wires that are part of the electric fence must run near to
high-voltage lines, then they may not be installed more than 3 m above the ground.
This height applies to each side of a right-angled projection from the outer conductor
of the high-voltage cable on the area for a distance of
• 2 m for high-voltage lines that operate at a
rated voltage of up to 1000 V;
• 15 m for high-voltage lines that operate at a rated voltage over 1000 V.
Electric fences intended for scaring o birds, for keeping pets or training animals, e.g.
cows (cow trainer), should only be supplied by a low power energiser (which still has a
sucient and secure eect). Where an electric fence is intended to prevent birds from
nesting on buildings, no wire of the electric fence may be grounded if the fence wires
are not connected to metal parts.
If a wire is connected to a metal par t (such as gutter) or a metal structure in the building, then this metal part must be grounded. A warning sign must be attached at all
points where people are able to access the conductors.
Where an electric fence crosses a public footpath, a non-electried gate or stile must
be present. Each of these stiles must be tted with warning signs indicating that the
fence is an electric fence. Each part of an electric fence that runs along public streets
or other public rights of way must have warning signs securely attached to the fence
posts or wires at regular inter vals. Connecting wires that run below the ground must
be placed inside protec tive insulated pipes or insulated high-voltage cables must be
DE UK FR IT NL SE
Page 9
used. It is important to ensure that connec ting cables cannot be damaged by external
inuences (such as animal hooves, tractor wheels, etc.) that sink into the soil. Connecting
lines may not be installed in the same protective pipes as mains and supply cables,
communication or data lines.
Connecting cables and wires belonging to electric fences may not be laid above highvoltage or communications cables. Crossing high-voltage cables should be avoided.
If crossing over a high-voltage cable cannot be avoided, then the cable must be laid
below the high-voltage cable and be as close to a right-angle with it as possible.
Warning signs must be at least 100 x 200 mm in size. The background colour on both
sides of the warning sign must be yellow. The text on the warning sign must be black.
The text must read “ Warning: Electric Fence” or similar. The text on the warning
sign must printed in a durable way and be at least 25 mm in height. Ensure that all
mains-powered supporting equipment connected to the electric fence circuit has a
degree of insulation between the fence circuit and mains supply which corresponds
to that of the energiser.
9. DISPOSAL
If you wish to dispose of the energiser, please contact a local disposal company or
recycling centre. Alternatively, you may contac t VOSS GmbH & Co. KG. All consumers
