Three-phase installations with more than one switch board
The three-phase installations with ONLY one switchboard should concentrate all the circuits with ONLY protected
with the same RCCB. Like this ONLY a D-BUSDRV is necessary for the installation.
If there are more than one switchboard or ONLY modules are divided by more than one RCCB, it is necessary to
use a floor driver D-FDRV, that provides not ONLY the BUS drive for the floor but also an isolated BUS
connection to another floor.
The electrical diagrams of the switchboards are as follows:
The connections in the switchboards are as follows (note that ONLY the automation part is indicated):
