Be sure to follow all applicable local electrical wiring
codes.
DO NOT install the controller on the same line or

Installing and Wiring the Controller
CAUTION:
DO NOT wire 120 volts directly to the PC board
terminals; the transformer supplied with the controller
MUST be used.
3. Connect the green ground wire directly to the terminal
labeled “GND”
In areas where lightning is prevalent or the condition of the third wire
ground is questionable, a ground rod must be installed. Connect the
grounding rod to the controller’s case ground using a
#lO gauge or
heavier stranded copper wire.
The distance from the controller’s case to the earth ground should
be minimized.
