5.2.1 MBUS Communication

If MBUS is selected, no RS485 communications cable is required to connect to the
SUN2000, but the AC power cable needs to connect to a SmartLogger that
supports MBUS.
The MBUS communication mode is only applicable to medium-voltage grid
connection scenarios and non-low-voltage public grid connection scenarios
(industrial environment).
