4. Align the bracket with the screw and use the inner hexagonal wrench to screw the tapping screw until the expansion bolt bang is heard.
5. Hang the buckle on the inverter to the corresponding position of the backplane.
6. Use the inner hexagonal wrench to tighten the inner hexagonal screw on the right side of the inverter.
7. Strip off the 7mm insulation layer of the wire end using a wire stripper.
8. Pass the cable through the fastening head and alignment plug of the PV connector. Note that the red and black lines correspond to different pairs of plugs.
9. Force the cable into the plug until a click is heard to indicate that the connection is complete.
10. Tighten the fastening head and insert the corresponding positive and negative (PV-/PV+) ports of the inverter.
11. Before inserting the PV terminal, turn on the switch of the PV module, and use a multimeter to measure the positive and negative DC voltage range of 1100V DC.
