Connect the voltage supply 24 VDC. This can be done with the integrated
DIN connector or, alternatively the 2-pole screw clamp (24 V = »+«;
GND = »-«). Pay attention to the correct polarity.
5.
You may now install the delivered software as described in the chapter 8
or 9.
While connecting the DC voltage pay attention to the correct polarity,
otherwise electronics may be damaged.
