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.

6. Use a pre-crimped cable to connect via gland #1 to the RJ45 plug on the inverter's
communication board or, if using a spool of cable, connect as follows:
a. Insert the cable through gland #1.
b. Remove the cable's external insulation using a crimping tool or cable cutter and
expose eight wires.
c. Insert the eight wires into an RJ45 connector, as described in Figure 23 .
(1) The inverter connection does not support RX/TX polarity change. Supporting crossover Ethernet cables
depends on the switch capabilities.
