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.

Inductive load devices such as motor starters and solenoids require the use of some type of surge suppression to protect the controller output contacts. Switching inductive loads without surge suppression can significantly reduce the life expectancy of relay contacts. By adding a suppression device directly across the coil of inductive devices, you prolong the life of the output circuits. You also reduce the effects of radiated voltage transients and prevent electrical noise from radiating into system wiring and facility

The following diagram shows an output with a suppression device. We recommend that you locate the suppression device as close as possible to the load device.

Suitable surge suppression methods for inductive load devices include a varistor, an RC network, or, for dc loads, a diode. These components must be appropriately rated to suppress the switching transient characteristic of the particular inductive device. See the table on page 18 for recommended suppressors.

If you connect a micro controller triac output to control an inductive load, we recommend that you use varistors to suppress noise. Choose a varistor that is appropriate for the application. The suppressors we recommend for triac outputs when switching 120V ac inductive loads are a Harris MOV, part number V175 LA10A, or an Allen-Bradley MOV, catalog number 599-K04 or 599-KA04. Consult the varistor manufacturer's data sheet when selecting a varistor for your application.
