5.2 Crimping the OT Terminal
Requirements for the OT Terminal
● If a copper cable is used, use a copper wiring terminal.
● If a copper-clad aluminum cable is used, use a copper wiring terminal.
● If an aluminum alloy cable is used, use a copper to aluminum adapter
terminal or an aluminum wiring terminal with a copper to aluminum adapter
washer.
● 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 IEC61238-1.
● 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.
