3-3 Aluminum cable requirements
If the aluminum cable is selected, in order to ensure a reliable electrical
connection, use the the copper and aluminum conversion terminal to avoid
direct contact between the AC copper bar and the aluminum cable.

Conversion terminal
Directly connecting the aluminum cable to the copper bar will cause
abnormal operation or even device damage.
3-4 Second PE Cable Connection
A second protective earth (PE) terminal is equipped at the side of the PCS. Be
sure to connect this PE terminal to the PE bar for reliable grounding and ensure
that the grounding resistance should be less than 10 Ohm.
In European and Asia-Pacific regions, this secondary protective
grounding connection cannot replace the connection of the terminals
in the AC wiring. Both shall be reliably grounded. Otherwise, Sungrow
will not take any responsibility for the possible consequences.
