IMPORTANT If you use wires without lugs, make sure the wires are securely captured 

by the pressure plate. This is particularly important at the four end 

terminal positions where the pressure plate does not touch the outside 

wall of the controller.

IMPORTANT Be careful when stripping wires. Wire fragments that fall into the 

controller could cause damage. Remove the protective wrap after wiring 

your controller. Failure to remove the wrap may cause the controller to 

overheat.

IMPORTANT This symbol denotes a functional earth ground terminal which 

provides a low impedance path between electrical circuits and 

earth for non-safety purposes, such as noise immunity improvement.

Grounding Your Controller

In solid-state control systems, grounding helps limit the effects of noise due to 

electromagnetic interference (EMI). Run the ground connection from the ground screw of 

the controller (third screw from left on output terminal rung) to the ground bus. Use the 

heaviest wire gauge listed for wiring your controller.
