2. Click on OK to load all parameters including the communication parameters from the
device into Switch ES Power where they can be changed.
3. In the tree on the left side, select the point "Communication" and select the desired new
address in the drop-down field.
4. In the "Target System" menu, select the entry "Load in Switching Device". This transfers
