3.1.3 Electrical Grounding of the Controller
Proper electrical grounding is required to ensure safety to you, as well as to protect the controller
electronics in the event of electrical line surges, such as lightning. In areas where lightning is a
common occurrence; it is strongly recommended to use the RME EAGLE model EG-T.
3.1.4 Grounding Instructions
1.
Mount the controller as close as possible to the grounding rod, using 10 AWG grounding wire,
attach one end of the wire to the controller ground lug and the other end to the ground rod. The
wire should be as short as possible. Ensure the grounding wire is free of any nicks or sharp
bends.
2. Use a ground rod clamp to secure the ground wire to the ground rod. Be sure all surfaces are
clean of oxides and dirt, and that all connections are solid and secure.
3. In areas of very dry soil or sand, it may be necessary to "Dope" the grounding rod. Contact your
local Rain Master distributor or Rain Master Irrigation Systems for a pamphlet on grounding
techniques titled “RMIS Grounding”.
4. It is important that the ground rod be a full 8 feet into the ground, with only enough of the rod
exposed to clamp the ground wire. The 8 foot ground rod should completely penetrate the soil
at a right angle, if this is not possible; it is acceptable to put the ground rod into the soil at a
slight angle (slightly less than 90 degrees).
5. Should other grounding installation requirements be necessary, contact your local distributor or
Rain Master Irrigation Systems.
NOTE: It is important to periodically check the ground resistance to ensure it is not
greater than 10 ohms. Contact your local Rain Master Distributor for
details.
