HOW TO INSTALL EARTH (GROUND) SYSTEM

Improperly earthed Energizers can cause barns, gates etc to become electrified. Follow earthing instructions carefully.
The most effective place for an earth system is in continuously damp soil (illustration a).

For dry areas with poor earthing conditions, install the fence using illustration b.

Earth stakes, at least 2m (6ft) long, should be spaced 3m (10ft) apart. Use a minimum of 3 earth stakes for the
M1800.

Fence Lead-out
Inadequate fence lead-out is often the reason for poor voltage on the fence. Particularly on either
larger fence systems or fence systems heavily loaded with vegetation.
Lead-out is defined as the wire system that takes the power from the Energizer to the centre of
the fence system – not just from the Energizer to the fence! Basically, the more wires connected in
parallel, the better the voltage at the end of the fence.
If the centre of the fence system is more than 100m (300 ft) from the Energizer, at least 1 x 2.5mm
wire is required. If the centre of the fence system is more than 1km (5/8 mile) from the Energizer,
a minimum of 3 x 2.5mm wires or a single High Conductive 2.5mm "PowerWire" is required. Larger fence
systems or heavily loaded fence systems with large Energizers may require more wires to adequately transfer
the power from the Energizer onto the fence system.
