Fig 6.18 Standard cable wiring
CAT5/6 standard cables have eight wires (four twisted pairs), as shown in the diagram
below. Wire colors may differ from one cable to another. You can use either wiring
standard, as long as both sides of the cable have the same pin-out and color-coding.
Insert the conduit into the right side COM drill guide that was opened.
Insert the CAT 5/6cable through the conduit to the inverter wiring box.
Remove the cable's external insulation using a crimping tool or cable cutter and
expose eight wires.
Insert the eight wires into an RJ45 connector, as described in Fig 6.18.
Use a crimping tool to crimp the connector.
Connect the signal cable from the battery to the RJ45 port on the communication
board.
Keep the wiring box clean.
