3.2.1 Main voltage and stepper motor wiring
The power supply of the controller is 230V AC; +/- 10%. Cable of the power supply should be connected on the
terminals marked with letters “L”, “N” and “PE” (see Figure 15). Cables should be inserted via dedicated cable
entries/glands. After the wiring is performed, remember to re-tighten the cable glands and avoid pulling out or
twisting.
Stepper motor is assembled with the integrated cable and connected to the controller via dedicated extension cable.
Both of them are ended with the 4-pole connectors allowing for quick connection. Locking pawl of terminals will ensure
the firm installation of both cables. Do not shorten the cables.
