Therefore, an important step in the installation process is to properly
connect the controller to an earth ground source, especially if the
controller is located in a lightning-prone area.
Caution: The built-in surge protection components cannot
effectively protect the controller circuitry from power surge
unless properly connected to an earth ground source.
To connect an earth ground:
1. Route a #12 (2mm
2 ) solid copper wire in the shortest and most
direct path from the “Earth Gnd” lug, located on the terminal
board, to an earth ground source such as metal water pipe or
copper-clad ground rod.
2. Clamp the end of the ground wire securely to the pipe or ground
rod. Make sure the wire contact area is free of dirt and corrosion.
