    For multiple inverters, inverters are “daisy-chained” together using twisted pair signal cable with the first inverter in the chain connected to the Aurora Universal. The Aurora Universal is connected to the internet using CAT-5 or CAT-5 compatible cabling.
  • Page 4 Blue/white Green Brown/white Brown Device Mounting  The exact method of mounting the Aurora Universal enclosure is left to the installer. Here are some tips and best practices: • Ambient temperature around the box should remain between –20 C and 60 (this should be verified) •...
  • Page 5 Preparing Inverters for Connection to Aurora Universal  Inverters must be connected to each other in a daisy chain before being connected to Aurora Universal. The RS-485 serial port uses a three-wire cable, two wires are for signals and a third one for ground connection. RJ12 ports and appropriate cabling can serve as the connection between inverters.
  • Page 6 RJ12 ports depending on the Aurora inverter. An example terminal block from an Aurora inverter is shown below. For easier installation, the inverter typically features two holes so that input and output cables can be separated when multiple units are connected in a daisy chain.
  • Page 7 Terminate the last inverter. Make sure the last inverter is terminated as per the Aurora inverterdocumentation. The DIP switch on the last inverter’s RS-485 terminal block must be set to ON. See the figure in step 4 above for an example of the DIP switch that needs to set to ON for the last inverter.
  • Page 8 Connect the power supply wire to 120, 208, or 240VAC. Connect Instruments  If you have no meter in the Aurora Universal, skip this section. Instruments are attached to Aurora Universal only if you have a revenue grade meter with your system (Aurora Revenue Grade). The Aurora Universal System comes without holes for electrical connections to the enclosure.
  • Page 9 Connect the RS-485 data cable from the Data Logger to the RS-485 terminal block in the first Aurora inverter in the chain using the pin callouts in Table 1. Refer to the diagram and table below to make the proper connections. Refer to the Power-One Aurora Inverter installation documentation for details on the RS-485 terminal block location.
  • Page 10 You now ready to test power and the physical connections. Either a cellular router, LAN switch, or LAN router must be connected through the LAN1 port of the Data Logger. Turn on the power to the Aurora Universal using the breaker on the DIN Rail.
