1.5.6 I/O Wiring Requirements
I/O wiring requirements are site and application dependent. Local, state, or NEC requirements
determine the I/O wiring installation methods. Direct burial cable, conduit and cable, or overhead
cables are options for I/O wiring installations. Section 2 contains detailed information on connecting
I/O wiring to the EF-Series Unit.
The Main Electronics Board containing the field wiring terminal connections is accessed by opening
the door after removing the lock (if installed) and releasing the hasp on the right-hand side. The input
terminal wiring is arranged on the lower edge of the Main Electronics Board. The terminal
designations are printed on the circuit board.
