Step 2. Install the Earth system
Buildings and gates for example, can become electri
fi
ed with fence voltages if the
energizer is improperly earthed.
Follow earthing instruc ons carefully
.
a)
Install at least 3 x 2.1m (7 ) galvanised earth stakes into damp soil where
possible. In dry condi ons or in low mineral content soil more earth stakes
may be required. Earth stakes must be at least 3m (10 ) apart and at least
10m (33 ) away from any mains cabling, telephone cabling, water pipes or
building earth.
Do not
connect the earth terminal to any building metal work or
framing.
b) To
a ach the earth cable:
1.
Using Underground Cable (G627) remove 5cm (2”) of plas c coa ng from
one end of the cable wire and connect to the green (
) terminal on the
energizer.
2. A ach the cable to the earth system by removing 10cm (4”) of insula on
from the cable at each Earth Stake (G879) and then clamp the exposed
wire to each stake using an Earth Clamp (G876).
3.
Tighten the clamp.
Note:
Poor grounding can cause interference on telephone lines, radios and
televisions. This can be recognised by a clicking sound on telephones
.
Reference Earth
An addi onal earth stake is required to measure the earth system performance.
a)
Install a single galvanised stake (G878 / G879) at least 60cm (2 ) long, at least
10m (33 ) from the main energizer earth system and at least 10m (33 ) from
any mains cabling, telephone cabling, water pipes or building earth.
b)
Using Underground Cable (G627) connect the reference earth stake to the
black (ref earth symbol) terminal on the energizer.
