Communications Wiring for Multiple Inverters

6. Connect the network cable to an empty RJ45 port in Inverter #2.
7. For more than two inverters, continue connecting cable as described above.
8. If not already installed, insert male network terminators into the empty RJ45
ports in the inverters at the beginning and end of the network.
After connecting network cables and inserting terminators, there should be no
empty RJ45 ports in any connected inverter.
9. After completing network cabling, tighten all cable clamps (ensuring there is
adequate slack in the cable tension) and replace the communication ports
covers on all units. See Figure 3-12.
Verifying the Xanbus Network
For long Xanbus networks (greater than 100 m), you must verify network
integrity using a CANbus network analysis tool such as the Maretron N2KMeter
Diagnostic Tool for NMEA 2000 compatible networks. To determine if the
network is healthy, check to see if any bus errors are present on the network. The
presence of bus errors, specifically more than one bus error per second, indicates
that the network is not operating optimally.
CAUTION
For the inverter to meet regulatory requirements, the communication ports cover must be
installed.
