Always turn off the source circuit breaker and check to ensure the power is off to the controller through the
use of a tester prior to working on the wiring terminals.
Never touch the terminals in the rear panel when power is supplied to the controller.
Be sure to turn off the electric power before wiring any terminals.
Bind the wires connected to the controller terminals neatly together in order to
prevent electromagnetic interference.
