6.2 Connecting the Generator
You can connect a three-phase generator to the Multicluster-Box, e.g., a diesel generator or
another grid-forming power generator. However, you also have the option of connecting it to the
utility grid. The line conductors L1, L2, and L3 are routed via a fuse switch-disconnector in the
Multicluster-Box. Fuse links with a nominal current of 80 A are factory-installed.
