A Crimping an OT or DT Terminal
Requirements on an OT or DT Terminal
● If a copper cable is used, use copper wiring terminals.
● If a copper-clad aluminum cable is used, use copper wiring terminals.
● If an aluminum alloy cable is used, use copper-to-aluminum wiring terminals,
or aluminum wiring terminals along with copper-to-aluminum washers.
● Do not connect aluminum wiring terminals to the AC or DC terminal blocks.
Otherwise electrochemical corrosion may occur, aecting the reliability of cable
connections.
● Comply with the IEC 61238-1 requirements when using copper-to-aluminum
wiring terminals, or aluminum wiring terminals along with copper-to-
aluminum washers.
● Do not mix up the aluminum and copper sides of a copper-to-aluminum
washer. Ensure that the aluminum side of the washer contacts the aluminum
wiring terminal, and that the copper side contacts the terminal block.
