Step 4: Connect the positive cable of the battery pack to the “DC+” of the DC terminal block
so that the angle between the cable and the terminal block is 90 degrees.
Step 5: Connect the negative cable of the battery pack to the “DC-” of the DC terminal
block so that the angle between the cable and the terminal block is 90 degrees.
Step 6: Confirm wiring firmness and lock of DC cable.
Remark: The angle of 90 degrees between the cable and the terminal is for convenient
installation of the DC side protective case.
DANGER
Turn off AC and DC distribution switches and ensure that there is no
dangerous voltage in the system during wiring.
CAUTION
The positive and negative poles of batteries cannot be connected
inversely. Before wiring, a multi-meter needs to be used for
