Wiring Your Controller 3-5
Recommended Surge Suppressors
Use the Allen-Bradley surge suppressors shown in the following table
for use with relays, contactors, and starters.
Grounding the Controller
In solid-state control systems, grounding and wire routing helps limit
the effects of noise due to electromagnetic interference (EMI). Run the
ground connection from the ground screw of the controller to the
ground bus prior to connecting any devices. Use AWG #14 wire. For
AC-powered controllers, this connection must be made for safety
purposes.
