4.3.2. 4.3.2 Connection of binary signals

The general binary signals terminal blocks (shown in the following image) do not present any particular connection technique.

However, it is important to ensure that voltages with difference reference levels must not be mixed within the same connector. The following two images provide connection examples:

DC signals connection

*It must be ensured that the voltage reference (GND) is the same for all the voltages to be monitored

AC signals connection

*It must be ensured that the neutral wire is identical for every voltage to monitor

!DO NOT connect voltages with different reference levels to the same terminal block
