Step1:

Please connect the wire of DC according to the following steps:

Operation Instruction

Operation Demonstration

1. Connect DC wire and cold terminal

(SC35-8

）

firmly by crimping plier.

Step2:

Through the PV waterproof terminal on the terminal cover, fix the DC wire (PV +,

PV -) on the terminal, pay attention to the positive and negative poles shouldn’t be
connected reversely, and ensure that the circuit breaker at the DC side of the system is
in the off state.
