All sensors, power supplies, and communication devices areconnected to the system using environmentally-sealed connectors. All theconnectors are labeled and located on the bottom flange of the electronicenclosure. See also Appendix A, Wiring Diagrams, on page 263 for anoverview of AWS330 wiring.NOTE Be careful not to bend the connector pins when connecting the cables.1012-199Figure 53 Connector Flange of the EnclosureThe following numbers refer to Figure 53 above:1 = Maintenance terminal COM0 connector2 = AC (mains) input power connector3 = Static pressure head tube4 = Grounding rail for common grounding point5 = Solar panel connectorStatic Pressure HeadStatic pressure head (number 3 in Figure 53 above) minimizes field-induced error in pressure measurement.
