NO TICE
● Do not connect aluminum wiring terminals to the AC terminal block. Otherwise
the electrochemical corrosion will occur and affect the reliability of cable
connections.
● Comply with the IEC61238-1 requirements when using copper-aluminum
transition wiring terminals, or aluminum wiring terminals along with copper-
aluminum transition spacers.
● If copper-aluminum transition spacers are used, pay attention to the front and
rear sides. Ensure that the aluminum sides of spacers are in contact with
aluminum wiring terminals, and copper sides of spacers are in contact with the
AC terminal block.
