FE Contacts One of the roles of the DIN rail is to provide a FE for the modules on the island. FE

provides the island with noise immunity control and RFI/EMI protection. The

contacts on the back of the NIM, shown in (3) below, make the functional ground

connection between the rail and the NIM. See Functional Earth (FE) on the DIN Rail,

p. 73.

5 When the module is pushed completely on to the rail, the clips will snap closed.
