5.2.1 General information
Power supply terminals and Ethernet interfaces are placed on the top of the device (Fig. 2.3. Pos.1). Mating
plug for the power supply is included.
Terminal assignments are given in Fig. 5.3 and Tab. 5.1.
Electrical connections for inputs and outputs are given in Fig. 5.4…5.10.
Maximum conductor cross-section is 1.0 mm².
Plug-in terminal block for power supply and removable terminal block for I/O connections enable quick and
easy replacement of the device (see Fig. 5.2).
When wiring is completed, the wires should be placed in a special recess under the cover so that adjacent
devices can be placed on the DIN rail close to each other.
