Overvoltage protective equipment – lightning diverter
To prevent from damages caused by lightning, we recommend leading a circuit of fence
system near to building via overvoltage protective equipment – lightning diverter fastened to
outer masonry of the building by means of non-combustible materials before its connecting
to energizer. This applied also for combined energizers, if they are used together with a
network adapter.
Generally, we recommend connecting network powered electric fence system only to
such supply networks that are protected with earth-leakage circuit breaker with maximum
actuating current of 30 mA. In addition to that, correct installation of energizer with auxiliary
discharger 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
energizer, 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, connection 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 energizer 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.
Service 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
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.
