The steps to assemble the DC connectors are listed as follows:
1. Strip off the DC wire for about 7mm, Disassemble the connector cap nut. (see Figure 4.10)
3. Crimp the contact pin to the wire using a proper wire crimper. (see Figure 4.12)
2. Insert the wire into the connector cap nut and contact pin. (see Figure 4.11)
4. Insert the contact pin to the top part of the connector and screw up the cap nut to
the top part of the connector .(see figure 4.13).

Caution:
If DC inputs are accidently reversely connected or inverter is faulty or not
working properly, it is NOT allowed to turn off the DC switch as it will damage
the inverter and even leads to a fire disaster.
The correct actions are:
*Use a clip-on ammeter to measure the DC string current.
*If it is above 0.5A, please wait for the solar irradiance reduces until the
current decreases to below 0.5A.
*Only after the current is below 0.5A, you are allowed to turn off the DC
switches and disconnect the PV strings.
Please note that any damages due to wrong operations are not covered in
the device warranty.
