Step 4 Route the PV input power cable through the conduit and then fitting of the pipe.
Step 5 Connect the PV input power cable to the terminal block. connect positive
pole(+) of connection cable to positive pole(+) of PV input terminal block, connect
negative pole(-) of connection cable to negative pole(-)of PV input terminal block,
please pay attention to PV input voltage and current within permission.
Step 6 Secure the fitting to the conduit.
Step 7 Checks that the cables are connected correctly and securely. Then take
