Technical data Electrical connection and installation The controller consists of the housing and the back panel. The electronics are integrated into the housing. The back panel contains the terminal block. Two wires of 0.75 mm2 may be connected to each terminal. For wall mounting, fasten the back panel with the terminal block to the wall. After installing the connecting lines, attach the housing. For panel mounting, insert the housing into the prepared panel cut-out and secure it. After installing the connecting lines, attach the housing. Ordering text Programmable Logic Controller (PLC)...
