1.Prepare RJ45 connector and a communication cable.
2.Trip the insulation from the communication cable.
3.Let the communication cable pass though the waterproof plug, then insert
it into the RJ45 connector following the PIN definition rule.
4. Crimp the RJ45 connector with the crimping plier.
5.Insert the cable into the DRM port of the inverter, and tighten the
waterproof plug.
RS 485/Meter
This is a communication interface provided for engineer to adjust the inverter.
a. RS 485
b. Meter(optional)
1.Monitor the energy to grid and from grid throughout the whole day.
2.Achieve the export control function with a higher accuracy.
