1.4.3
Fastening The Wire To The Ground
It is not necessary to bury the perimeter wire, though you may do so if you wish, up to 10 cm
(4 inches) deep.
Small pegs or stakes are supplied with the Robomow and they are used to fasten and hold the
perimeter wire to the ground, below grass level.
Initially place a minimum number of pegs to fasten the wire down. Remember that you will want to
test the wire set up before you fill in additional pegs and you may find some areas where you will
need to move the wire position slightly.
Upon hammering the peg to its final depth in the ground, pull the wire tight. It is a lot easier to insert
pegs into wet soil. If the soil is dry, water the yard before perimeter wire set up.
WARNING!
Damage to the eye is possible. Use proper eye protection and wear
appropriate work gloves when hammering the pegs. Hard or dry ground
may cause pegs to break when driving them in. In extreme cases,
watering the lawn where the pegs will be driven can be beneficial.
Add pegs in to pull
the perimeter wire down
to the ground surface,
below the grass tips.

Pegs should be driven at distances between one
another that will keep the wire down below the
grass level and prevent it from becoming a tripping
hazard (Figure 1.15).
When properly fastened to the ground, the wire and
pegs will soon disappear under the growth of new
grass and will not be visible.
If additional wire is required in order to complete
the set-up, use the wire connectors provided, which
are water-proof, to connect between the two wire
ends, as explained in chapter 5.6.

Pegging the Perimeter Wire
IMPORTANT INFORMATION!
Screw terminals or twisted cables, insulated with insulation tape is not a satisfactory splice. Soil
moisture will cause the stripped wire ends to oxidize and after a while result in broken circuit.
1.4.4 Completing The Perimeter Wire Setup
Once the perimeter wire is completed and pegged to the ground, the last step to complete is
attaching the perimeter wire ends to the Base Station board and testing the setup.
There are two loose wire ends where the perimeter wire set up was started (Figure 1.16).
Use the same peg to fasten these two perimeter wire ends down to the ground and twist them.
Cut the wire end without the connector so they are of equal length - removing any excess wire.
Strip back 6 mm of insulation from the wire end (Figure 1.17).
Insert the free perimeter wire into hole of connector using a small flat screwdriver; tighten the
screw to secure the perimeter wire into the connector (Figure 1.18).
