K3 Contact Data; K62 Contact Data; Efficiency - ABB ACS880-37LC-0390A-7 Hardware Manual

186 Technical data
The contacts of both relays are wired to a terminal block in the drive cubicle; see the
drive-specific circuit diagrams for details. The external voltage switched by the contacts is
to be connected to the same terminal block.
