Aluminium Cable Requirements
If an aluminium cable is selected, use a copper to aluminium adapter terminal to avoid direct
contact between the copper bar and the aluminium cable.

Ensure that the selected terminal can directly contact with the copper bar. If there
are any problems, contact the terminal manufacturer.
Ensure that the copper bar is not in direct contact with the aluminum wire. Other-
wise, electrochemical corrosion may occur, impairing the reliability of electrical
connection.
5.5 External Protective Grounding Connection
Electric shock!
• Make sure that the ground cable is connected reliably. Otherwise, it may cause
electric shock.
• Since the inverter is not equipped with a transformer, neither the negative elec-
trode nor the positive electrode of the PV string can be grounded. Otherwise,
the inverter will not operate normally.
• Connect the grounding terminal to the external protective grounding point be-
fore AC cable connection, PV string connection, and communication cable
connection.
