Connecting Sensor Cables 
Connect the sensor cables to the enclosure after mechanically installing 
the sensors. All sensors, power supplies, and communication devices are 
connected to the system using environmentally-sealed connectors. All the 
connectors are labeled and located on the bottom flange of the electronic 
enclosure. See also Appendix A, Wiring Diagrams, on page 263 for an 
overview of AWS330 wiring. 
NOTE 
Be careful not to bend the connector pins when connecting the cables.

Figure 53  Connector Flange of the Enclosure 
The following numbers refer to Figure 53 above: 
1  =  Maintenance terminal COM0 connector 
2  =  AC (mains) input power connector 
3  =  Static pressure head tube 
4  =  Grounding rail for common grounding point 
5 = Solar panel connector 
 
Static Pressure Head 
Static pressure head (number 3 in Figure 53 above) minimizes field-
induced error in pressure measurement.
