Notes:
−
Do not use other settings than the ones mentioned in the table
−
It is recommended to assign increasing addresses starting from the main master
at the left and moving right
−
Assigning the same address to different units in one system will lead to the
system not being able to start up and go in error (Bad Ratings)
When a system consists of more than one unit, attention has to be paid to the proper
termination of the communication bus between the different units. This communication
bus is depicted in the below
by the black lines interconnecting the different
units.

From previous unit (if present)
To next unit (if present)
Figure 81: Communication bus between different units
In order to terminate the bus correctly, the fourth switch (counting from left to right)
from DIP switch 22 (Cf.
) has to be set as follows:
−
High: For the first unit in a system (single unit or first physical unit of a multi-unit
inverter)
−
High: For the last physical unit of a multi-unit inverter
−
Low: For all the other units
