Connecting output
Connect the
black earthing output
to the earthing rod using earthing cable.
Connect the
red output
to the fence system using the connecting cable.
Yellow output
is intended for connecting fence system where we always require reduced
energy in order that animals receive weaker, approximately half strength impulse; this
relates to fence system for younger and smaller animals (foals, calves). It is also connected
separately to the larger fence system lower wire, where vegetation is expected to be
dense with technical measures to prevent losses, namely voltage leakage to the ground
as it is usual in standard connections thus the energizer power output is not reduced. The
other wires connected to the red output are powered separately at full voltage.
Green output
is intended for measuring the quality of earthing to find out whether the
existing earthing is satisfactory or requires upgrading due to the location, e.g. adding
another earthing rod, irrigate it or repair connections. It is always required to install
measuring electrode located 10 m from the energizer earthing point. Use non-corroding
well conducting rod at least 20 cm long for the measuring electrode. Connect high voltage
cable to the green energizer connection.
Ground voltage shown
on the energizer display
Status
0 to 0,20 kV
OK
0,20 to 0,50 kV
Check earthing; add another earthing
rod as a precaution
> 0,5 kV
Carry out repairs or add earthing rod
It is also important what fence system impedance the energizer measures. If the energizer
shows impedance of 500 Ohm or lower, i.e. long or overgrown fence system then there is no
need to install anything else and the earthing check works automatically. Check the ground
voltage on the energizer according to the below table.
If the fence system impedance is higher than 500 Ohm, i.e. quality fence not subjected to
load, then it is required to short-circuit the fence system to enable the measurement and thus
determine the quality of earthing. To carry out short-circuiting, the overhead fence system
wire is earthed at a location of at least 50 m from the energizer. Use good quality earthing rod,
hammer it into the ground and connect it to the wire, subsequently check the ground voltage
on the energizer according to the following table.
