Accordingly one Slave after the other has to be connected to the RS485 bus and be taken
in function. For the Slave_5 module this picture is valid analogously.

MASTER
Here can only be described how to bring the Slave modules in operation for the
measurement of the cell voltages which is the same in each application. We thought it
important to refer to the proper connection between Slave and battery that often showed
difficulties for some first users.
All starting ups happen in the responsibility of the system manufacturer.
