1. Aurora H2O has three ¾” NPT conduit inlet ports for power and I/O (see Figure 24 below). These will normally be
shipped plugged from the factory. Follow the applicable wiring code and requirements for wiring the unit.
Figure 24: Conduit Inlet Ports
Note: Use one conduit inlet for power. Use the two other conduit inlets for input/output as needed. All unused
conduit inlet ports should be sealed with suitable blanking elements.
2. Select one conduit for inlet power to the Aurora H2O based on your configuration. The Aurora H2O comes with a
universal power supply, or optionally, as a 24VDC powered unit. Remove the wiring cover to view the wiring
