INSTALLATION
Proper Installation Of Ground Rod
Machine To Earth
Grounding
good contact with the surrounding soil, making a proper ground.
5. Connect the bare, copper ground wire to the rod with the
proper ground rod clamp.
6. Connect the bare ground wire to control panel with a grounding lug.
7. Ground wire must not have any breaks or splices. Insulated
wire is not recommended for grounding applications.
(Ground rods and wires are not supplied by Manufacturer). It is recom-
mended that the rod not be driven into dry ground. Follow these instruc-
tions for proper installation.
1. Dig a hole large enough to hold 1 to 2 gallons of water.
2. Fill hole with water.
3. Insert rod through water and jab it into the ground.
4. Continue jabing the rod up and down. The water will work its
way down the hole, making it possible to work the rod com-
pletely into the ground. This method of installation assures
Previously Installed Units
It is recommended that previously installed units be checked to see
that a machine to earth ground has been properly installed by an elec-
trician.
Figure 4: Use a #6 or approved
size bare copper ground wire.
Install a 5/8" diameter 8' long
copper-clad ground rod, 2'
away from the foundation and
1' below the surface of the
ground or in accordance with
local requirements.
Dig a hole large enough to hold 1
or 2 gallons of water. Work the
ground rod into the earth until it is
completely in the ground.
It is very important that a
Ma-
chine To Earth Ground Rod
be
installed at the fan. The ground
rod needs to be as close to the fan
as possible, but no more than 8
feet away. The ground rod should
be connected to the fan control
panel with at least a #6 solid, bare,
copper ground wire. The ground-
ing rod located at the power pole
will not provide adequate ground-
ing for the fan. The proper
grounding will provide additional
safety if there is a short and will
ensure long life of all circuit
boards used on control circuits,
and the ignition system. The
ground rod must be in accordance
with local requirements.
