Electrical connection

6.5  Connecting Modbus cable

There is risk of damaging components if you install in the wrong sequence!

► 

First connect the Modbus leads to the power meters and afterwards to 

terminal block X1 in the storage system.

Communication between the power meters and the storage system is implemented
over Modbus. The Modbus cable transmits a data signal (A and B) and provides a 
signal ground (GND).
