Frequently asked
questions/Troubleshooting
What voltage is required to control animals?
4 kV is widely accepted as the recommended
minimum voltage to control animals. However,
you also require a well constructed fence system
to ensure that animals cannot push through
electrified wires.
The fence voltage is below 4 kV. How do I
increase the voltage?
Check the energizer.
from the energizer's fence output terminal.
Measure the voltage across the energizer
terminals with a Fault Finder or Digital
Voltmeter. If the voltage is less than 6 kV, the
energizer may require servicing.
Check the energizer earthing.
procedure described in
earth system
on page 74.
Check the fence system for faults.
common source of low voltage is faults on the
fence line.
If the fence, earth and energizer are in good
condition and the voltage is still below 4 kV,
talk to your nearest reseller. Recent extensions
to your fence, a poor fence layout, or soil
conditions may be causing inadequate voltage.
How do I locate faults?
The recommended tool for locating faults is a
Fault Finder. This combined voltage and current
meter allows you to rapidly locate sources of
current leakage. Alternatively, use a Digital
Voltmeter. Use cut-out switches to turn off the
power to different sections of the farm. If the
voltage on the fence increases when a section
of the farm is turned off, then investigate that
section for possible faults.
There are no lights flashing on the energizer.
Ensure the power supply is on. Check the fence
system for faults (see above). Check the
energizer (see above). If the energizer still does
not operate, it may require servicing.

Servicing
This energizer uses Double Insulation, where
two systems of insulation are provided instead
of grounding. No equipment grounding means
is provided in the supply cord of a
double-insulated energizer, nor should a means
for equipment grounding be added to the
energizer. Servicing a double-insulated
energizer requires extreme care and knowledge
of the system and should only be done by
qualified service personnel. Replacement parts
for a double-insulated energizer must be
identical to the parts they replace. A
double-insulated energizer is marked with the
words DOUBLE INSULATION or DOUBLE
INSULATED and/or the symbol below.
