WAC155 has 3 plug-in I/O connectors: X1, X2, and X3. The terminals accept wires with maximum cross-section area of 1.5 mm2.

Figure 2. I/O connectors

For the location of the connectors and the cable routing through the cable glands, see Sensor Wiring.

The following tables show the I/O connector pinouts.
