Directly connecting an aluminum wiring terminal to the AC terminal block will cause
electro-chemical corrosion and weaken the cable connection reliability.
The copper to aluminum adapter terminal or an aluminum wiring terminal with a copper to
aluminum adapter washer must comply with UL486-A and UL486-B.
Do not mix up the aluminum and copper sides of the copper to aluminum adapter washer.
Ensure that the aluminum side of the washer contacts the aluminum wiring terminal, and
the copper side contacts the AC terminal block.
