Connecting the binary input and output signals

Auxiliary power and signals are connected using voltage connectors. Signal wires are connected to
a female connector (see Figure 29) which is then plugged into the corresponding male connector
(see Figure 30) located at the rear of the IED. For location of BIM, BOM, SOM and IOM refer to

connectors". Connection diagrams for BIM, BOM, SOM and IOM are shown in
22 and Figure 23.
Do not insert anything else to the female connector but the corresponding male
connector. Inserting anything else (such as a measurement probe) may violate the
female connector and prevent a proper electrical contact between the printed
circuit board and the external wiring connected to the screw terminal block.
