Setting up for earth monitoring
The earth monitoring feature works by comparing the voltage of the
energizer’s earth system with that of a separate earth rod. Ensure the
separate earth rod is at least 10 m (33’) away from any other earth
system including the energizer’s main earth system. Locate the earth
rod in the opposite direction to the lead out wire. Drive one 2 m (6’6”)
earth rod into the ground. Use high-voltage, insulated cable and an
earth clamp to connect the earth rod and the energizer’s Fence earth
monitor terminal. Make sure the insulation is stripped back to ensure
good contact between the wire and the earth rod.
Monitoring the earth
If the first Indicator light is illuminated permanently, this indicates that
the earth voltage is over 0.8 kV and that better earthing may be
beneficial. Either add more earth rods or find a better location for the
energizer earth system. The small digits on the LCD display show the
voltage going to the earth system when the selector switch is set to
,
,
or
. The earth voltage should remain below 0.8 kV
at all times. If the earth monitor voltage numbers flash 3.0 kV, this
indicates the earth voltage is above 3.0 kV. See
Installing and testing
an earth system
on page 9 for information about installing an earth
system effectively.
Testing the battery voltage
The energizer’s Battery Test setting can be used to monitor the battery
voltage.
When the selector switch is set to Battery Test
, the Indicator lights
show the input supply voltage. This can be useful in order to monitor
the battery charge level.
Note:
When the selector switch is set to Battery Test
, the energizer
pulses at slow speed (2.5 seconds between pulses) and the fence is live.

Battery selection and management
This section refers exclusively to 12 V rechargeable batteries.
The batteries you select will depend on whether your installation is a
solar or a battery-only installation. For both types of installation, the
selector switch position you use most frequently will be a factor. Refer
to
Operation
on page 4 for an explanation of the function of the
selector switch.
