a. Use the network wire stripper to strip the insulation layer off the communication cable.
Using the standard wire sequence referenced in TIA/EIA 568B, separate the wires in the cable.
Use a network cable tool to trim the wire. Flatten the wire in the order shown in figure 5.29.

Installation
6.1 Start the Inverter
To start up the Inverter, it is important that the following steps are strictly followed:
1. Switch the grid supply main Switch (AC) ON first.
2. Switch the DC switch ON. If the voltage of PV arrays are higher than start up voltage,
the inverter will turn on. The red LED power will light.
3. When both the DC and the AC sides supply to the inverter, it will be ready to generate
power. Initially, the inverter will check both its internal parameters and the parameters
of the AC grid, to ensure that they are within the acceptable limits. At the same time,
the green LED will flash and the LCD displays INITIALIZING.
4. After 30-180 seconds (depending on local requirement), the inverter will start to generate
power. The green LED will be on continually and the LCD displays GENERATING.
WARNING:
Do not touch the surface when the inverter is operating. It may be
hot and cause burns.
6.2 Stop the Inverter
To stop the Inverter, the following steps must be strictly followed:
1. Switch the Supply Main Switch (AC) OFF.
2. Wait 30 seconds. Switch the DC Switch OFF.
Alter approximately one minute, all LEDs will turn off.
3. If removing the inverter, disconnect the input and output cables after 5 minutes.
6. Start & Stop
b. Insert the wire into the RJ45 connector then crimp the connector with the crimping tool.
c. Unscrew the cap nut from the COM2/3 cable glands and remove the plugs.
d. Insert the RJ45 connector into the RJ45 port in the inverter maintenance chamber.
e. Replace the cap nuts for COM2/3 and tighten firmly.
NOTE:
After connecting, check the correctness and firmness of the connection.
After confirmation, seal the connector and cable with a suitable sealant.
