Machine to Earth Grounding
It is very important that a machine to earth ground rod be installed at the dryer. Place the ground rod that
comes standard, within eight feet (8') of the dryer and attach it to the dryer control panel with at least a #6
solid, bare, copper ground wire and the clamp provided. The grounding rod located at the power pole will
not provide adequate grounding for the dryer. The proper grounding will provide additional safety
in case of any short and will ensure long life of all circuit boards, SCR drive, and the ignition system.
The ground rod must be in accordance with local requirements.
Proper Installation of Ground Rod
It is not recommended that the rod be driven into dry ground. Follow these instructions for
proper installation.
1. Dig a hole large enough to hold one (1) to two (2) gallons of water.
2. Fill hole with water.
3. Insert rod through water and jab it into the ground.
4. Continue jabbing the rod up and down. The water will work its way down the hole, making it possible
to work the rod completely into the ground. This method of installation assures good contact with the
surrounding soil, making a proper ground.
5. Connect the bare, copper ground wire to the rod with proper clamp.
6. Connect ground wire to control panel with the ground lug provided in the control box.
7. Ground wire must not have any breaks or splices. Insulated wire is not recommended for
grounding applications.
Connecting Auxiliary Conveyors
The auxiliary load augers or conveyors can be wired directly to the dryer. The maximum horsepower of
auxiliary that can be wired to the dryer is 10 horsepower. If an auxiliary motor is larger than what is
recommended, then it must be powered from a source outside the dryer, and must use a separate
contractor and overload protection device for each motor. However, the operation of the auxiliaries can be
performed by the control panel.
It is recommended that you contact the local power company and have a representative survey the
installation to see that the wiring is compatible with their system and that adequate power is supplied
to the unit. Remember that the only thing connected to the recommended service amps should be the
grain dryer. Standard electrical safety practices and codes should be used. (Refer to National Electrical
Code Standard Handbook by National Fire Protection Association.) A qualified electrician should make all
electrical wiring installations.
