Overvoltage protective equipment – lightning diverter
To prevent from damages caused by lightning, we recommend leading a circuit of fence sys-
tem near to building via overvoltage protective equipment – lightning diverter fastened to
outer masonry of the building by means of non-combustible materials before its connec-
ting to energizer. This applied also for combined energizers, if they are used together with
a network adapter.
Overvoltage caused by storm can cause insulation of
electric fence system. In such a case, network voltage
can get into electric fence system, and serious danger to
people or animals can occur.
Avoid direct contact with fencing, especially with head, neck or upper part of body. Do not
creep through the fencing or over it. For passing the fence system, use a gate or another point
in installation designed for this purpose.
Generally, we recommend connecting network powered electric fence system only to such
supply networks that are protected with earth-leakage circuit breaker with maximum actua-
ting current of 30 mA. In addition to that, correct installation of energizer with auxiliary dis-
charger and choking coil is necessary, as described within these instructions. It is suitable to
disconnect network supplied electric fence system from network as well as from fencing (if
possible) during storm.
If a network with earth-leakage circuit-breaker was not used for purposes of supplying ener-
gizer, and the enrgizer was connected to the fence system or the network during storm, it
is necessary to check and test it before putting it into operation again. For this purpose, co-
nnection to network with earth-leakage circuit-breaker must be available. For purposes of
testing, connect earthing output of energizer to protective conductor of the supply network
and connect pin to power socket protected with earth-leakage circuit-breaker then. If ener-
gizer beats correctly and does not show any deviations from normal operation subsequently,
it can be connected to fence system again. If the earth-leakage circuit-breaker however falls
out when energizer is connected, you must not use it and it must be repaired professionally
If connecting lines of this energizer are damaged, they must be replaced by manufacturer or
authorized service or another qualified person so that possibility of danger is excluded. Servi-
ce and repairs of these energizers must be performed by authorized persons only! Each user
of electric fence system is responsible for its operation and should perform regular checks of
energizer and fence system at least once a day, depending on operating conditions!
Procedure of checking:
• Visual control of energizer and fence system
• Measuring of minimum voltage of 2500 V in every place of the fence system
If installation is performed inside a building, energizer may not be operated in a room with
increased risk of fire in any case (barn, shed, cattle shed). In addition to that, no combustible
materials may be stored near to fence system and connectors of energizer. Installation of ener-
gizer must be made on a fire-resistant surface.
For stable using, use only energizers designed for that purpose!
