Connecting an Earth Ground Device
Note: In order for the electrical surge components built into your
Rain Dial-R to function properly, the controller must be connected to
an earth ground device, such as a copper-clad ground rod or metal
water pipe, using solid copper wire. This connection is especially
important when the controller is installed in a lightning-prone area .
1 . Connect a 12–16 AWG ( 2mm
the ground device and route into the controller through an access
opening in the base of the cabinet .
2 . Secure the ground wire to the terminal labeled "Earth Ground ."
